| ○ | ○ | Article | Drought Tolerance of 'Fuji' Apple Trees Grafted onto G, CG, or M Series Rootstocks: Growth and Physiology | In this study, we assessed the drought tolerance of 1-year-old apple (Malus domestica Borkh.) trees exposed to extreme water stress, focusing on growth and physiological responses. After grafting 'Fuji' variety onto M26 and M9 rootstocks or Cornell-Geneva rootstocks (G11, G202, G214, G935, CG4814, and CG5087), the grafted plants were planted in 17-L pots and managed in a greenhouse. After irrigation was stopped, soil water potential dropped to about -700 hPa in 12 days. The leaf water potential and tree vertical growth rate of drought-stressed trees decreased dramatically, and the decreased growth rate of the G202, G935, and M26 trees, which generally produced a large leaf area, was considerable. Trunk cross-sectional area and leaf area of all trees under drought stress were reduced by almost 50% or more than 60%, respectively. Drought-stressed trees were subjected to control-level irrigation during the recovery of about 11 days, but their leaf water potential still did not fully recover to the control level. Photosynthesis-related parameters also showed a substantial decrease as the soil water potential changed, but the difference among trees was not noticeable. Fine root (<2 mm diameter) dry weight showed the greatest decrease in the CG5087 tree, whereas the G935 tree was insensitive. The root:shoot biomass ratio of the CG5087 and M26 trees was 0.24 and 0.23, respectively, and 0.38 for the G214 and CG4814 trees. The CG5087 tree was the most sensitive to drought stress, whereas drought tolerance was higher in the G202, G214, and G935 trees than in the M26 tree, which had a comparable drought tolerance to the G11, CG4814, and M9 trees. | Choi, Byeong-Ho; Bhusal, Narayan; Jeong, Woo-Tae; Park, In-Hee; Han, Su-Gon; Yoon, Tae-Myung | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Apple Res Inst, Daegu 41566, South Korea | Bhusal, Narayan/AAE-9086-2019 | 57212379669; 57199327486; 57217307960; 57217313022; 57199650006; 50263701700 | tmyoon@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 5 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.13 | 2025-06-25 | 3 | 3 | apple rootstock; dry matter; photosynthesis; water deficit; water potential | MALUS-DOMESTICA BORKH.; WATER-STRESS; STOMATAL CONDUCTANCE; CITRUS TREES; OLIVE TREES; IRRIGATION; RESPONSES; PHOTOSYNTHESIS; TRANSPIRATION; MORPHOLOGY | Apple rootstock; Dry matter; Photosynthesis; Water deficit; Water potential | English | 2020 | 2020 | 10.7235/hort.20200054 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of 1-Methylcyclopropene Treatments on Fruit Quality Attributes and Cell Wall Metabolism in Cold Stored 'Summer Prince' and 'Summer King' Apples | This study was conducted to investigate the effects of different concentrations (0.5 and 1 mu L.L-1) and application times (0.5, 1, 0.5+0.5 and 1+1 mu L.L-1) of 1-methylcyclopropene (1-MCP, SmartFresh (TM)) treatment on post-harvest quality and cell wall metabolism of 'Summer Prince' and 'Summer King' apple fruit during cold storage. Compared with control fruit, 1-MCP treatments maintained higher flesh firmness and titratable acidity in both apple cultivars. In contrast, the soluble solids content did not show differences in all treatments. The internal ethylene concentration was higher in control fruit, but fruit with 1-MCP treatments expressed lower ethylene concentration. Weight loss in ' Summer Prince' fruit treated with 1-MCP was lower than in control fruit during storage. The starch index did not show differences in all treatments; on the other hand, greasiness or other storage disorders were not detected during storage. Both cultivars showed higher contents of total sugar and uronic acid in both 1-MCP treatments than the control. 'Summer Prince' apple had increased cell wall degrading enzyme activity of beta-Gal, alpha-Gal, beta-Glc, alpha-Man, and alpha-Ara enzymes after 4 months of storage in control fruit. Likewise, 'Summer King' apple had increased activity of beta-Gal, beta-Glc, beta-Xyl, and alpha-Ara enzymes after 2 months of storage in the control fruit. Both cultivars showed lower cell wall degrading enzyme activities in 1-MCP treatments than in the control. In conclusion, 1-MCP treatment of ' Summer Prince' and 'Summer King' apple fruit was effective in maintaining quality by inhibiting internal ethylene and cell wall metabolism. However, the different concentrations and repeated applications of 1-MCP treatment were not different in this study. Therefore, it was suggested that 0.5 mu L.L-1 1-MCP treatment could be considered an economically effective concentration for this study. | Yoo, Jingi; Kim, Seon-Hyang; Kwon, Jung-Geun; Cho, Young-Je; Kang, In-Kyu | Washington State Univ, Tree Fruit Res Extens Ctr, Wenatchee, WA 98801 USA; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | 56818324500; 57219443035; 57211404168; 55265396300; 56577308800 | kangik@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 5 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 1.03 | 2025-06-25 | 5 | 8 | ethylene; flesh firmness; beta-galactosidase; storability; uronic acid | MALUS-DOMESTICA BORKH.; STARCH DEGRADATION; SUPERFICIAL SCALD; 1-MCP; POSTHARVEST; STORAGE; ETHYLENE; TEMPERATURE; PREHARVEST; GREASINESS | Ethylene; Flesh firmness; Storability; Uronic acid; β-galactosidase | Korean | 2020 | 2020 | 10.7235/hort.20200060 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effects of Preharvest Aminoethoxyvinylglycine and Pre- or Postharvest 1-Methylcyclopropene Treatments on Fruit Quality Attributes during Cold Storage in 'Misshong' Peaches | This study was carried out to investigate the effects of preharvest aminoethoxyvinylglycine (AVG, ReTain (R)) and sprayable 1-methylcyclopropene (1-MCP, Harvista (TM)) and postharvest 1-MCP (SmartFresh (TM)) treatments on fruit quality in cold-stored 'Misshong' peaches. Flesh firmness of control fruits was decreased to 2.9 Newton (N) after 3 days of storage. However, a week before harvest (WBH) ReTain (R) and SmartFresh (TM) treatments maintained firmness at 7.9 N and 12.0 N for up to 6 days of storage, respectively. Titratable acidity of control fruits was decreased from 0.33% at harvest to 0.21% after 12 days of storage. However, ReTain (R) and SmartFresh (TM) treatments maintained acidity at 0.26 and 0.30% until 12 days of storage, respectively. Ethylene production of control fruits was highly increased to 45.4 mu L.kg(-1).h(-1) after 12 days of storage, while at 1 WBH ReTain (R) (23.9 mu L.kg(-1).h(-1)) and SmartFresh (TM) (21.6 mu L.kg(-1).h(-1)) treatments resulted in lower ethylene production than control fruits. Soluble solids content of 1 WBH ReTain (R) (10.5 degrees Brix) was slightly lower than control fruits (11.0 degrees Brix) at harvest, and fruit weight loss was not affected during the storage progress. Therefore, this study suggested that 1 WBH ReTain (R) and SmartFresh (TM) treatments help maintain fruit quality in 'Misshong' peaches during cold storage. | Yoo, Jingi; Park, Chulho; Kwon, Jung-Geun; Lee, Dong Hoon; Jung, Hee-Young; Cho, Young-Je; Kang, In-Kyu | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Gyeongsan Agr Technol Ctr, Gyongsan 38443, South Korea; Natl Inst Hort & Herbal Sci, Fruit Res Div, Wonju 55365, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | 56818324500; 57211580127; 57211404168; 55568531225; 7403029383; 55265396300; 56577308800 | kangik@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 3 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0 | 2025-06-25 | 1 | 2 | ethylene; flesh firmness; fruit storability; Harvista (TM); ReTain (R) | CONTROLLED-ATMOSPHERE STORAGE; ETHYLENE BIOSYNTHESIS; 1-MCP TREATMENT; DROP; AVG; MATURITY; METABOLISM; APPLES; NAA | Additional ethylene; Flesh firmness; Fruit storability; Harvista™; ReTain<sup>Ⓡ</sup> | Korean | 2020 | 2020 | 10.7235/hort.20200035 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Functional Properties of Newly-Bred 'Summer King' Apples | In this study, we investigated the various physiological properties of 'Summer King' apples (Malus domestica Borkh) to highlight this fruit as a high value functional food source. The peels of newly-bred 'Summer King' apple were extracted using water and ethanol, and each extract demonstrated relatively high levels of phenolic compounds at 4.41 mg.g(-1) and 7.39 mg.g(-1), respectively. The water and ethanol extracts also showed antioxidant protection factor (PF) levels of 3.37 PF and 2.65 PF, respectively, and the antioxidation effects towards thiobarbituric acid reactive substances were 38% and 30% at 100 mu g.mL(-1) phenolic concentrations. Therefore, extracts of 'Summer King' apple possess substantial properties for anti-aging. The anti-inflammatory effect (hyaluronidase inhibition) of the extracts were 4.97% for the water extract and 20.40% for the ethanol extract, both at a 200 mu g.mL(-1) phenolic concentration. Both the water and ethanol extracts showed low alpha-amylase inhibition effects, but each demonstrated 93.59% and 98.80% alpha-glucosidase inhibition at a 200 mu g.mL(-1) phenolic concentration, respectively. In an anti-wrinkle assay, the water extract showed 14.55% and 67.73% inhibition of elastase and collagenase, respectively, and the ethanol extract had 56.50% and 77.81% inhibition, respectively. These results support the high potential for the use of these extracts in functional food and cosmetics, and the 'Summer King' apple peel was determined to have various functions including anti-oxidation, anti-inflammation, anti-wrinkle, and anti-diabetic effects. | Lee, Eun-Ho; Cho, Eun-Bi; Kim, Byung-Oh; Jung, Hee-Young; Lee, Seung-Yeol; Yoo, Jingi; Kang, In-Kyu; Cho, Young-Je | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea | 56347429100; 57204068582; 7501567571; 7403029383; 56106499600; 56818324500; 56577308800; 55265396300 | yjcho@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 3 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.39 | 2025-06-25 | 5 | 6 | anti-diabetic; anti-inflammation; anti-oxidation; anti-wrinkle; phenolics | ANTIOXIDANT ACTIVITY; PHENOLIC CONTENT; ACID; INHIBITION; HEALTH; TISSUE | Additional anti-diabetic; Anti-inflammation; Anti-oxidation; Anti-wrinkle; Phenolics | English | 2020 | 2020 | 10.7235/hort.20200039 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Induction of Tetraploidy in Watermelon with Oryzalin Treatments | This study evaluated the effect of different concentrations and methods of oryzalin treatment on polyploidization in watermelon (Citrullus lanatus). The first method involved different concentration of oryzalin (0, 5, 10, 15, 20, and 25 mg.L-1) applied to the shoot apex of watermelon seedlings. Polyploidy was not induced by concentrations of 10 mg.L-1 or lower. In contrast, mixoploidy was observed with concentrations of 15 and 20 mg.L-1 and 84% of the plants were tetraploid in the 25 mg.L-1 concentration. The addition of the surfactant tween 20 in oryzalin was less effective for tetraploid induction than oryzalin alone. The second method involved soaking the seeds in different concentrations of oryzalin (0, 30, and 35 mg.L-1). With this method, the 30 mg.L-1 oryzalin concentration did not induce polyploidy and the 35 mg.L-1 concentration only induced tetraploidy in 25% of the plants. The morphological features of the second true leaf of a tetraploid plant showed a small, thick, and wrinkled leaf unlike that of the diploid plant. In addition, the number of stomata per unit area decreased and stomata doubled in size in the tetraploid plants. Tetraploid plants (2n = 4x = 44) were confirmed by counting the number of chromosomes of the treated plants. We concluded that the shoot apex treatment with 25 mg.L-1 oryzalin was the most effective method for inducing tetraploid watermelon. | Bae, Su-Jin; Islam, Md Mazharul; Kim, Hong-Yul; Lim, Ki-Byung | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | Islam, Md Mazharul/AFS-6460-2022; Islam, Mazharul/AFS-6460-2022 | 57209454284; 57219091958; 56941037200; 7403175915 | kblim@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 3 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 1.94 | 2025-06-25 | 15 | 19 | chromosome doubling; leaf shape; seed soaking; shoot apex treatment; stomata size | IN-VITRO INDUCTION; COLCHICINE TREATMENT; POLYPLOIDY; PLANTS; POLYMERIZATION; CULTIVAR; TUBULIN; HYBRIDS | Additional chromosome doubling; Leaf shape; Seed soaking; Shoot apex treatment; Stomata size | English | 2020 | 2020 | 10.7235/hort.20200037 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Phenotype and Ploidy Analysis of the Colchicine-induced M1 Generation of Echeveria Species | Mutation breeding is an important tool for developing new cultivars in horticulture. Among the many methods of mutation breeding, chemical mutation is highly effective and can be performed easily. Compared to natural breeding methods, higher mutation rates and the faster induction of desirable characteristics have been reported with the use of chemical mutagens. Succulents have recently gained popularity because of their unique geometrical shapes and their ability to survive with minimal watering. Succulents that have peculiar shapes and colors demand higher prices. In this study, we used colchicine, a chemical mutagen, and tested its application on three Echeveria succulent species. A phenotypic evaluation was conducted on the mutant succulents produced from the application of colchicine on propagated leaf cuttings. Phenotypic evaluation included plant parameters and morphological analysis. Ploidy analysis was conducted to confirm the effects of the mutagen treatments. In all selected Echeveria species, the use of colchicine produced mutant species that varied significantly from those of the control; however, treatment concentration and duration varied per species. The phenotypic evaluation revealed that colchicine-mutated plants exhibited compactness, with mutants being generally taller with a thicker but shorter plant diameter compared to that of the control. Mutated plants exhibited prominent changes in color for the a* and b* values. Similarly, changes in leaf shape were observed and were evident at their apexes. These morphological changes are attributed to the change in ploidy level, which was confirmed through stomata and ploidy analysis. Larger stomata size was accompanied by lower stomata density. Based on the flow cytometry analysis, mutated succulents exhibited a 2x-4x complex. | Cabahug, Raisa Aone M.; Ha Tran Thi My Khanh; Lim, Ki-Byung; Hwang, Yoon-Jung | Sahmyook Univ, Chromosome Res Inst, Seoul 01795, South Korea; Sahmyook Univ, Dept Convergence Sci, Seoul 01795, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea | park, jun yeon/GPX-5293-2022 | 57211922965; 57218586992; 7403175915; 50061210800 | hyj@syu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 4 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.26 | 2025-06-25 | 4 | 5 | chemical mutagen; mutation; ornamental; plant breeding; succulents | POLYPLOIDY INDUCTION; INDUCED MUTANTS; RESPONSES; SPP. | Chemical mutagen; Mutation; Ornamental; Plant breeding; Succulents | English | 2020 | 2020 | 10.7235/hort.20200049 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Phenotypic Characteristics and Karyotype Analysis of Hibiscus sabdariffa var. sabdariffa by Fluorescence in Situ Hybridization (FISH) | The aim of this research was to ascertain the chromosome number, karyomorphology, distribution of 5S and 18S rDNA loci, individual chromosome length, total chromosome length, DNA content, genome sizes, and phenotypic characteristics of H. sabdariffa var. sabdariffa . The chromosome number and detailed karyotype were analyzed by fluorescence in situ hybridization (FISH) using 5S and 18S rDNA probes. H. sabdariffa var. sabdariffa was tetraploid, and the chromosome number of somatic cells was 72 (2n = 4x = 72). According to FISH analysis, four 5S rDNA loci and ten 18S rDNA loci were detected. The lengths of the somatic chromosomes ranged from 3.53 to 6.88 mu m, with a total chromosome length of 97.95 mu m, where the total length of short arms and long arms were 37.16 and 60.79 mu m respectively. The somatic cells of this species had twelve pairs of metacentric (m) and six pairs of submetacentric (sm) chromosomes. The karyotype formula was K = (2n) = 4x = 72 = 48m + 24sm. In this experiment, DNA content and genome sizes of H. sabdariffa var. sabdariffa were estimated by flow cytometry. 2C-DNA content and 2C genome size were 4.29 pg and 3338.8 Mbp, respectively. The leaf shape, leaf apex, and leaf margin were ovate, acute, and palmatipartite, respectively. The flower colour was purple and single in type. In addition, the diameter of the flower was 7.2 cm and the length of the flower eye was 1.87 cm. These results will contribute to further breeding and cytogenetic studies of H. sabdariffa var. sabdariffa. | Mohammad, Deepo Deen; Mazharul, Islam; Ann, Tapce Cherry; Kim, Hong-Yul; Lim, Ki-Byung | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | Islam, Md Mazharul/AFS-6460-2022 | 57209270990; 57219091958; 57219449811; 56941037200; 7403175915 | kblim@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 5 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.77 | 2025-06-25 | 8 | 9 | breeding; cytogenetics; loci; 5S rDNA; 18S rDNA | LILIUM-RUBELLUM; HYBRIDS; CYTOGENETICS; LONGIFLORUM; CHROMOSOMES; PLANTS; L. | 18S rDNA; 5S rDNA; Breeding; Cytogenetics; Loci | English | 2020 | 2020 | 10.7235/hort.20200063 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Prediction of Strawberry Growth and Fruit Yield based on Environmental and Growth Data in a Greenhouse for Soil Cultivation with Applied Autonomous Facilities | The ability to predict how well crops will grow and how much fruit they will yield is important for farmers, consumers, and researchers. Advances in environmental and plant measurement equipment provide the opportunity for more data to be collected from plant growing operations, which could result in more accurate predictions. The objective of this study was to predict the strawberry growth and fruit yield using environmental and growth data collected with this equipment. The correlation coefficients of the average daily air temperature and soil temperature data for strawberry growth predictions were higher than the relative humidity, soil moisture content, electronic conductivity, CO2 concentration, photosynthetic active radiation, and vapor pressure deficit data. The correlation coefficients of photosynthetic active radiation, vapor pressure deficit, and relative humidity for strawberry yield prediction were higher than the other environmental data and all growth data such as plant height, crown diameter, and leaf length and width. The regression model using environmental data showed high correlation coefficients with the actual yield data (R-2 = 0.99). These results indicate that strawberry growth and fruit yield could be predicted using environmental data. | Sim, Ha Seon; Kim, Dong Sub; Ahn, Min Gyu; Ahn, Su Ran; Kim, Sung Kyeom | Kyungpook Natl Univ, Coll Agr & Sci, Dept Hort Sci, Daegu 41566, South Korea; Univ Calif Davis, Dept Plant Sci, 1636 East Alisal St, Salinas, CA 93905 USA | Kim, Dong/G-7392-2017; Kim, Sung Kyeom/AAD-9230-2019 | 57220890640; 15760138600; 57220893546; 57220895028; 50262290200 | skkim76@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 6 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 2.97 | 2025-06-25 | 29 | 32 | air temperature; forecast; photosynthetic active radiation; relative humidity; smart farming | LEAF SIZE; TOMATO; PHOTOSYNTHESIS; TRANSPIRATION; TEMPERATURE; EXCHANGE; LIGHT; WATER | Additional air temperature; Forecast; Photosynthetic active radiation; Relative humidity; Smart farming | English | 2020 | 2020 | 10.7235/hort.20200076 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Role of Growth Regulators in the Somatic Organogenesis of Haworthia Inflorescences in Vitro | This study investigated the effect of growth regulators on the somatic organogenesis of Haworthia inflorescences. The inflorescences of five Haworthia cultivars and one species were cultured on 1X and 0.5X MS media with/without growth regulators for organogenesis. Shoot and callus induction was observed for three of the five cultivars, whereas only callus induction was observed for the other two cultivars and one species. Of the two growth regulator-free media used, all explants performed better on 1/2 fold MS medium than on 1 fold MS medium in terms of shoot and callus induction. Conversely, among the six media supplemented with kinetin and 6-benzylaminopurine (BA), there was no shoot formation; however, a different response in callus formation was observed for H. splendens and 'White Wolf'. The callus induction of H. splendens was more vigorous than that of 'White Wolf'. In this study, better organogenesis from young upper parts of the inflorescences was observed. The highest shoot and root multiplication was observed on NAA containing medium, and no root formation was observed on BA containing medium. The highest shoot multiplication (20.8 +/- 0.29) was observed for 'Tiffany x Fertenon B Com' on 1.4 mg.L-1 BA containing medium within 18 weeks, whereas, the highest root induction was observed for Haworthia 'Natalie' on medium containing 0.05 mg.L-1 NAA. The results revealed that different parts of Haworthia inflorescences showed different organogenesis responses. Therefore, this study contributes to a better understanding of the organogenesis response of Haworthia cultivars on different media. | Reshma, Yesmin; Mazharul, Islam M.

| ○ | ○ | Article | The Fusion Transcript of Phytoene Synthase 1 Controls Yellow Fruit in Tomato | Tomato (Solanum lycopersicum) fruit color is an important aspect of quality in terms of appearance and nutrient content. Carotenoids, chlorophyll, and flavonoids are the main components responsible for tomato fruit color. Phytoene synthase (PSY) is the key regulatory enzyme involved in the first committed step of carotenoid biosynthesis. Here, we found that the yellow fruit of S. lycopersicum 'YF2359', which lacks carotenoids, was regulated by a single recessive gene and cosegregated with PSY1 in the F-2 population. Two different PSY1 transcripts, including the wild-type and mutant (fusion-type), were discovered in YF2359. The mutant was generated by the fusion of exons from two different DNA strands, namely, PSY1 and the antisense strand of CoA ligase, by trans-splicing. This yellow flesh phenotype, which was caused by a mutation of PSY1 and was undetected in S. lycopersicum 'LA4044', was predicted to nullify PSY because of amino acid substitutions in the conserved trans-isoprenyl diphosphate synthase domain. Additionally, the trans-splicing of PSY1 reduced wild-type PSY1 expression, suggesting that the metabolic flux in the carotenoid pathway was suppressed in the presence of this mutation. Carotenoid biosynthetic genes were expressed significantly less in 'YF2359' than in the red-fruited wild-type tomato 'M82'. Information on this unusual mutation in PSY1 will improve the understanding of genetic variations in plants and enable novel strategies for improving fruit quality. | Kang, Eun Sol; Lee, Je Min | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea | Lee, Je/AAE-7496-2020; Lee, Je Min/F-9797-2014 | 57219454134; 8885729900 | jemin@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 5 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.26 | 2025-06-25 | 2 | 2 | candidate gene; carotenoid; fruit color; molecular breeding; trans-splicing | PHYTOENE SYNTHASE 1; CAROTENOID BIOSYNTHESIS; COLOR MUTATIONS; BETA-CAROTENE; EXPRESSION; GENE; CLONING; METABOLISM; PATHWAY; GENOME | Candidate gene; Carotenoid; Fruit color; Molecular breeding; Trans-splicing | English | 2020 | 2020 | 10.7235/hort.20200064 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Compact circularly polarized metaresonator-enabled deca-band antenna | In this article, a circularly polarized small-sized deca-band monopole antenna is proposed and investigated. The proposed antenna consists of gun-shaped monopole radiator and split-ring resonator (SRR) array-loaded partial ground plane present on the top and bottom sides of the substrate, respectively. The antenna is excited by a microstrip line feed and in order to get varied multiband operation with circular polarization, several unique configurations of SRRs are employed as metaresonators. Using the approach of combining resonances of metaresonators and monopole radiator, dual-, triple-, hexa-, and deca-band operations can be achieved. The permittivity and permeability of the composite metaresonator structure made of SRRs are extracted to illustrate the working principle of the designed multiband antenna. The proposed multiband antenna covers long-term evolution, WLAN, WiMAX, bluetooth, satellite digital audio radio system (SDARS), radio altimeter, and satellite communication C-band applications, on a single multifunctional device, much needed in the fast-growing wireless industry. The antenna is fabricated on a 40 x 47 x 1.5748 mm(3) RT Duroid 5880 substrate, and simulations were carried out with the help of the tool Ansys HFSS. The simulated and measured results are in good agreement. | Alam, Maksud; Mainuddin; Kanaujia, Binod; Beg, Mirza; Kumar, Sachin | Jamia Millia Islamia, Dept Elect & Commun Engn, Fac Engn & Technol, Delhi 110025, India; Jawaharlal Nehru Univ, Sch Computat & Integrat Sci, New Delhi, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | ; MAINUDDIN, MAINUDDIN/ABA-8702-2022; Kumar, Sachin/W-2211-2019; kanaujia, Binod/L-6484-2019; Kanaujia, Binod/L-6484-2019; Mainuddin, Mainuddin/ABA-8702-2022 | 57204595541; 56490843400; 56962785800; 42261085500; 56907994000 | alam.maksud@gmail.com; | MICROWAVE AND OPTICAL TECHNOLOGY LETTERS | MICROW OPT TECHN LET | 0895-2477 | 1098-2760 | 62 | 2 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;OPTICS | 2020 | 1.392 | 77.1 | 0.08 | 2025-06-25 | 1 | 1 | circularly polarized; metaresonator; monopole; multiband; split ring | MONOPOLE ANTENNA; TEXTILE ANTENNA; ENHANCEMENT; DESIGN | circularly polarized; metaresonator; monopole; multiband; split ring | Antenna arrays; Antenna grounds; Circular polarization; Digital radio; Long Term Evolution (LTE); Monopole antennas; Radiators; Ring gages; Satellite antennas; Satellite communication systems; Slot antennas; Circularly polarized; metaresonator; monopole; Multiband; Split rings; Microwave antennas | English | 2020 | 2020-02 | 10.1002/mop.32058 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Effects of Changes in Analytic Variables and Contrast Material on Measurement of Computed Tomography Glomerular Filtration Rates in Healthy Candidates | Purpose This study aimed to prospectively assess the effects of changes in analytic variables and contrast material (CM) osmolality when measuring glomerular filtration rate using computed tomography (CT-GFR). Methods One hundred healthy participants were included in this analysis. Glomerular filtration rate was measured by technetium-99m diethylene-triamine-penta-acetic acid (Tc-99m-DTPA), and each participant underwent CT-GFR with iodinated CM (iohexol 240 or iobitridol 400) following a crossover study design. Dynamic renal CT scanning was performed. Patlak plot analysis was used to calculate GFR, selecting either the renal cortex or the whole kidney as the region of interest. The renal cortex was analyzed just before time of the second cortical attenuation peak. The whole kidney was analyzed 60, 80, 100, and 120 seconds after the appearance of CM. Automated GFR calculations were performed using perfusion software at 2 noise reduction levels (medium and strong). The CT-GFRs were compared with GFR measured by Tc-99m-DTPA. Results There was no significant difference in CT-GFR with iohexol 240 versus iobitridol 400. The CT-GFR at the renal cortex, for the whole kidney 60 seconds after appearance of CM and calculated by perfusion software with medium noise reduction, did not differ significantly from GFR measured by Tc-99m-DTPA. Whole-kidney CT-GFR at >= 80 seconds after CM appearance and CT-GFR calculated using perfusion CT software with strong noise reduction were lower when compared with GFR measured by Tc-99m-DTPA. Conclusion Results from CT-GFR were most accurate when the kidney cortex was selected as the region of interest or when using 60-second time point for whole-kidney assessment, regardless of CM osmolarity. | Kim, See Hyung | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Radiol, Daegu, South Korea | Kim, Sang-Hyun/J-5402-2012 | 57216511386 | kimseehyung72@outlook.kr; | JOURNAL OF COMPUTER ASSISTED TOMOGRAPHY | J COMPUT ASSIST TOMO | 0363-8715 | 1532-3145 | 44 | 2 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2020 | 1.826 | 77.1 | 0.09 | 2025-06-25 | 2 | 2 | computed tomography; glomerular filtration rate; Patlak plot analysis | BRAIN TRANSFER CONSTANTS; RENAL-FUNCTION; GRAPHICAL EVALUATION; HELICAL CT; HIGH-RISK; VOLUME | computed tomography; glomerular filtration rate; Patlak plot analysis | Adult; Aged; Contrast Media; Cross-Over Studies; Female; Glomerular Filtration Rate; Humans; Kidney; Male; Middle Aged; Osmolar Concentration; Prospective Studies; Radiographic Image Enhancement; Radiopharmaceuticals; Reference Values; Technetium Tc 99m Pentetate; Tomography, X-Ray Computed; Computerized tomography; Contrast media; Image segmentation; contrast medium; pentetate technetium tc 99m; radiopharmaceutical agent; Computed tomography; Contrast material; Glomerular filtration rate; Iohexol; Measurements of; Patlak plot analyse; Plot analysis; Region-of-interest; Regions of interest; Renal cortex; adult; aged; crossover procedure; diagnostic imaging; female; glomerulus filtration rate; human; image enhancement; kidney; male; middle aged; osmolarity; physiology; procedures; prospective study; reference value; x-ray computed tomography; Noise abatement | English | 2020 | 2020 (MAR-APR) | 10.1097/rct.0000000000000979 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | High frequency arbitrary waveform generator using a nonlinear transmission line | In this article, a high-frequency arbitrary waveform generator (AWG) based on Fourier synthesis theory is presented. A key element consists of a nonlinear transmission line (NLTL) that acts as a harmonic generator for large signals and as a phase shifter for small signals. The harmonics generated by the NLTL are separated into four channels using power dividers and each harmonic is bandpass filtered in each channel. The phase and the amplitude are then modulated in each channel by an NLTL phase shifter and a voltage variable attenuator. Finally, vector modulated signals from each channel are combined in Wilkinson power combiners to form any waveform shape. We used 0.5 GHz as a master signal and synthesized waveforms using all four channels. | Kim, Chanwoo; Bae, Jaemin; Han, Heeje; Park, Soonwoo; Kim, Hongjoon | Kyungpook Natl Univ, Coll IT Engn Elect Engn, Daegu, South Korea | 57203871025; 57210559591; 57191519438; 56843830300; 27169635900 | hongjoon@knu.ac.kr; | MICROWAVE AND OPTICAL TECHNOLOGY LETTERS | MICROW OPT TECHN LET | 0895-2477 | 1098-2760 | 62 | 3 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;OPTICS | 2020 | 1.392 | 77.1 | 0.16 | 2025-06-25 | 2 | 2 | arbitrary waveform generator; Fourier synthesis theory; harmonic generator; nonlinear transmission line; phase shifter | arbitrary waveform generator; Fourier synthesis theory; harmonic generator; nonlinear transmission line; phase shifter | Electric lines; Phase shifters; Waveform analysis; Arbitrary waveform generator; Fourier synthesis; Harmonic generators; High frequency HF; Modulated signal; Nonlinear transmission lines; Power combiner; Voltage variable attenuator; Harmonic analysis | English | 2020 | 2020-03 | 10.1002/mop.32182 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Low-profile circularly polarized planar antenna for GPS L1, L2, and L5 bands | In this paper, a circularly polarized (CP) planar antenna covering global positioning system (GPS) L1 (1575.42 MHz), L2 (1227.6 MHz), and L5 (1176.45 MHz) bands is presented. The antenna consists of an elliptical patch excited through the inset feed line. A pair of concentric ring slots is etched on the ground plane to achieve dual-band response that covers L5/L2 and L1 bands. The circular polarization is achieved by integrating a quarter-wavelength arc with the inset feed and loading a pair of slits on the elliptical patch. In addition, the quarter-wavelength arc improves the impedance bandwidth of the lower resonant band to cover the GPS L5 band. The antenna shows right-hand circular polarization (RHCP) in all the three bands. The antenna also satisfies the +/- 1 dBi gain flatness criteria of the GPS antenna. A prototype antenna is fabricated and experimental results are found in a good match with the simulated results. | Mishra, Shailesh; Das, Sushrut; Pattnaik, Shyam Sunder; Kumar, Sachin; Kanaujia, Binod Kumar | Indian Sch Mines, Indian Inst Technol, Dept Elect Engn, Dhanbad 826004, Jharkhand, India; Natl Inst Tech Teachers Training & Res, Dept ETV, Chandigarh, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea; Jawaharlal Nehru Univ, Sch Computat & Integrat Sci, New Delhi, India | Das, sushrut/V-9116-2019; kanaujia, Binod/L-6484-2019; pattnaik, shyam/AAR-4389-2020; Kanaujia, Binod/L-6484-2019; Mishra, Shailesh/LQJ-6460-2024; Kumar, Sachin/W-2211-2019 | 57213026346; 55834414200; 7006422314; 56907994000; 56962785800 | mishrashail1@gmail.com; | MICROWAVE AND OPTICAL TECHNOLOGY LETTERS | MICROW OPT TECHN LET | 0895-2477 | 1098-2760 | 62 | 2 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;OPTICS | 2020 | 1.392 | 77.1 | 0.73 | 2025-06-25 | 12 | 15 | circular polarization; elliptical; GPS; planar antenna; RHCP | STACKED PATCH ANTENNA; MICROSTRIP ANTENNA | circular polarization; elliptical; GPS; planar antenna; RHCP | Antenna feeders; Antenna grounds; Circular polarization; Electric impedance; Global positioning system; Microstrip antennas; Slot antennas; Circularly polarized; Dual band response; elliptical; Impedance bandwidths; Planar antennas; Prototype antennas; RHCP; Right-hand circular polarizations; Satellite antennas | English | 2020 | 2020-02 | 10.1002/mop.32077 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
