    Fruit firmness is largely determined by cell wall, cell shape, cell-to-cell adhesion, and tissue anatomy. This study was conducted to investigate cell wall ultrastructural changes and xylan distribution during ripening and softening of ‘Bluecrop’ highbush blueberry (Vaccinium corymbosum) fruits. Fruits at pale-green, reddish purple, and dark-purple stages, which represented large green, turning point, and ripe stages, respectively, were used in this study. Cell walls and middle lamella were degraded, while plasma membranes were separated from primary cell walls at the reddish purple and dark-purple stages. The immunofluorescence labelling of xylan was abundant at the pale-green stage once the fruits were firm. However, the labelling became weaker at the reddish purple and dark-purple stages, and it was not well confined to cell wall areas, implying cell wall alteration at late ripening stages. These results demonstrated that the cell wall, middle lamella, and xylans were extensively degraded during the ripening and softening of ‘Bluecrop’ highbush blueberry fruits. - COLLAPSE

    This study determined the relationship between the leaf-to-fruit ratio (LFR) and carbohydrate translocation in walnut tree. We artificially manipulated the LFR to analyze the specific mass transfer rate (SMTR), physical traits, carbohydrate content, and metabolism-related enzyme activity in the carpopodium of girdled fruit-bearing shoots with different LFRs. Our findings showed that when the same number of leaves was retained on the girdled shoots, the glucose content, acid invertase (AI) and sucrose phosphate synthase (SPS) activity, SMTR, and phloem area (PA) increased significantly with decreasing LFR (p < 0.05), whereas the sucrose and starch content, carpopodium diameter growth rate (CDGR), and carpopodium length growth rate (CLGR) did not change significantly (p > 0.05). When the same number of fruits was retained on the girdled shoots, the glucose, sucrose and starch content, AI and SPS activity, SMTR, CLGR, and CDGR of the carpopodium increased significantly with increasing LFR (p < 0.01), whereas the PA and carpopodium length did not change significantly (p > 0.05). The above results suggested that the carbohydrate translocation was adjusted by regulating the carpopodium AI activity by changing the LFR in walnut shoots, while the amount of carbohydrate allocated to the carpopodium was determined by the availability of carbohydrates from the sources. - COLLAPSE

    Nitrogen is a critical determinant of forest growth and productivity, and root respiration rate and nonstructural carbohydrates are important parameters for evaluating the effects of supplied nutrients. Here, we assessed the effects of nitrogen on walnut seedlings (Juglans regia Linn.) that grew consistently for a year under favorable conditions. Seedlings were potted in seven concentrations of N availability, 0, 1, 2, 4, 8, 12, and 16 mmol·L-1, and the specific root respiration rate and nonstructural carbohydrate content of the root system were determined via the off-body root system and the ketone color ratio methods, respectively. Nitrogen concentration was positively correlated with specific root respiration, and root diameter was the main factor related to specific root respiration and nonstructural carbohydrate content of walnut seedlings. Under the same nitrogen concentrations, the soluble total sugar and starch content of roots increased with increasing root diameter, while the specific root respiration increased with decreasing root diameter. Compared to the 0 mmol·L-1 nitrogen concentration, the content of nonstructural carbohydrates in the root system and the specific root respiration were higher when nitrogen concentration was N16. Our comprehensive analysis showed that a nitrogen concentration of N16 improved the respiration rate of the seedling root system, significantly increased the content of nonstructural carbohydrates in the seedling root system, and effectively promoted the growth and development of the seedling root system of walnut seedlings. - COLLAPSE

    The purpose of this study was to estimate the efficacy of 2% baking soda (sodium bicarbonate) and ultra-sonication on the fungi and bacteria disinfection and germination of organic vegetable seeds. The predominant fungi and bacterium were Altanaria sp. and Pseudomonas sp. in organic vegetable seeds. The treatment of 2% baking soda alone showed low germination rate of organic root, leafy vegetable and cucurbit seeds, but the germination and disinfection efficacy was increased by the combined treatment with 2% baking soda and ultra-sonication. Among the vegetable seeds, Radish, turnip, Chinese cabbage, and cabbage treated with 2% baking soda and ultra-sonication for one minute had the highest disinfection and germination efficacy. Also, beet, melon and watermelon were the highest disinfection and germination efficiency for 2 minutes of the combined treatment with 2% baking soda and ultra-sonication. In the future, the eco-friendly seed disinfection technology using ultra-sonication and baking soda is more effective and economical methods, so we need to expand research on other organic crops.


    본 연구에서는 2% 베이킹 소다와 초음파의 단독 및 혼합 처리가 근채류, 엽채류, 과채류 유기종자의 곰팡이와 세균의 소독 효과와 발아율에 미치는 영향을 검정하고자 하였다. 근채류, 엽채류, 과채류 유기종자에 우점하는 곰팡이와 세균에는 Altanaria sp.와 Pseudomonas sp.이 있었다. 2% 베이킹 소다 단독처리만으로는 근채류, 엽채류, 과채류 유기종자의 살균 효과가 낮았지만, 초음파와 혼합처리를 할 경우 발아율과 소독 효과가 상승하였다. 무, 순무, 배추 및 양배추 유기종자에서는 2% 베이킹 소다에서 초음파를 각각 1분간 처리하는 것이 살균 효과와 발아율에 가장 좋았다. 비트, 참외 및 수박 유기종자는 2% 베이킹 소다에서 초음파를 각각 2분간 처리하는 것이 살균 효과와 발아율에 가장 좋았다. 향후, 초음파와 베이킹 소다를 이용한 친환경 종자소독기술은 다른 기술보다 더 효과적이고 경제적이기 때문 다른 작물에 대한 확대 연구가 필요할 것으로 생각한다.

    In this study, we used transcriptome analysis of Vitis flexuosa to identify an E3 ubiquitin ligase RING1a gene, VfRING1a, which shows homology with the Arabidopsis PRC1-like core component AtRING1a. The CDS of the VfRING1a gene measures 1443 bp long and encodes 480 amino acids, including an N-terminal conserved RING domain, similar to Arabidopsis RING1a. To compare the structural distinction of VfRING1a from VvRING1a and AtRING1a, the locations of gene motifs were confirmed using a MEME motif search tool, and 3D steric structure of the RING1a genes was analyzed by a SWISS-MODEL protein structure prediction. We identified 12 and 8 conserved motifs dispersed throughout the protein sequences in VfRING1a and AtRING1a, respectively. The expression analysis of VfRING1a showed tissue-specific expression in various tissues, including leaves, flowers in prebloom and full bloom stages, and young and ripe berries. The expression pattern was investigated by inoculating grapevines with Botrytis cinerea, Colletotrichum acutatum, C. gloeosporioides, Elsinoe ampelina, and Rhizobium vitis and subsequent evaluation with quantitative real-time PCR. The VfRING1a gene was expressed differentially, depending on the inoculum used. We believe that these results provide meaningful data for further studies of the structure analysis and function of the VfRING1a gene in grapevines. - COLLAPSE

    This study investigated the growth characteristics and glucosinolate (GSL) levels of Chinese kale (Brassica oleracea var. alboglabra Bailey ‘Jellujon’) cultured within a plant factory using different concentrations of ammonium sulfate [(NH4)2SO4] and four different light-emitting diode (LED) combinations. In total, 16 combinations of the four (NH4)2SO4 concentrations and four LED light sources exerted significantly different effects on plant width, plant height, leaf length, leaf thickness, chlorophyll content, and the number of leaves. For the ratio combination of LED colors using blue light (B), red light (R), and white right (W), B0:R5:W5 showed the best growth characteristics, except for chlorophyll content. The leaf fresh weight (LFW) of Chinese kale did not change significantly with LED treatments, but varied significantly with (NH4)2SO4 treatments. S2 and S3 treatments among the (NH4)2SO4 treatments resulted in the largest increases in LFW under B0:R5:W5. Six major GSLs were identified, including as sinigrin (SIN), glucobrassicin, gluconapin, 4-OH glucobrassicin, 4-methoxy glucobrasscin, and neoglucobrasscin. The highest total GSL content was achieved with the combination of B0:R5:W5 and S4, but no significant difference was found among the (NH4)2SO4 treatments. For LEDs, B0:R5:W5 produced the highest total GSL levels. SIN was the dominant GSL under the combination of B0:R5:W5 and S4. In conclusion, the combination of S4 and B0:R5:W5was the most suitable for increasing total GSLs and SIN. - COLLAPSE

    This study was carried out to investigate the effects of preharvest aminoethoxyvinylglycine (AVG, ReTainⓇ) and sprayable 1-methylcyclopropene (1-MCP, HarvistaTM) and postharvest 1-MCP (SmartFreshTM) 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Ⓡ and SmartFreshTM 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Ⓡ and SmartFreshTM 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 µL·kg-1·h-1 after 12 days of storage, while at 1 WBH ReTainⓇ (23.9 µL·kg-1·h-1) and SmartFreshTM (21.6 µL·kg-1·h-1) treatments resulted in lower ethylene production than control fruits. Soluble solids content of 1 WBH ReTainⓇ (10.5°Brix) was slightly lower than control fruits (11.0°Brix) at harvest, and fruit weight loss was not affected during the storage progress. Therefore, this study suggested that 1 WBH ReTainⓇ and SmartFreshTM treatments help maintain fruit quality in ‘Misshong’ peaches during cold storage.

    More than 30 citrus varieties have been developed in Korea over almost four decades. Despite the economic importance of citrus fruit production, reliable technologies for the identification of citrus varieties bred in Korea have not been established. We developed 53 polymorphic nuclear microsatellite markers fully covering the nine pseudochromosomes of citrus and applied them to the discrimination of the 32 available citrus varieties bred in Korea. Most Korean citrus varieties were clearly discriminated by 245 alleles derived from the polymorphic microsatellite loci. However, nucellar or bud sport mutant varieties originated from Citrus hybrid ‘Shiranuhi’ could not be discriminated from each other because they share identical genotypes on all of the microsatellite loci investigated. The microsatellite markers developed in this study will be an efficient molecular genetic tool to protect breeders’ rights and guarantee the quality of nursery plants in the citrus industry. - COLLAPSE

    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. - COLLAPSE

    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 ½ 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 × 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. - COLLAPSE

    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 µg·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 µg·mL-1 phenolic concentration. Both the water and ethanol extracts showed low α-amylase inhibition effects, but each demonstrated 93.59% and 98.80% α-glucosidase inhibition at a 200 µg·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. - COLLAPSE
