The black raspberry fruit from the genus Rubus is highly consumed owing its flavor and health benefits, but the genetic basis of its cultivars is very limited with insufficient genetic information available. Therefore, breeding programs must focus on the exploitation of genetic diversity of wild crop relatives. We assessed the genetic diversity, population differentiation, and genetic structure of 11 wild relatives of R. coreanus Miq. using 10 microsatellite markers to collect valuable genetic information and propose enhanced strategies for development of breeding populations. The observed and expected heterozygosity were 0.493 and 0.520, respectively. Genetic differentiation among the populations was 0.109. The Mantel test confirmed that wild R. coreanus populations differentiated following isolation by distance. Moreover, Bayesian clustering analysis showed that R. coreanus populations consisted of three genetic clusters, distribution of those showed a geographical tendency. Based on the genetic diversity, private allele frequency, and genetic structure results, we suggest to preferentially include the Chiak, Hamyang, and Jeju populations for construction of a breeding population of the Korean black raspberry.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139557426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variegation can be divided into structural-type and pigment-type variegation. Foliar variegation was mostly caused by mutations in plastid genes. Even though there are various studies on foliar variegation in other plants, studies on foliar variegation in orchids are quite limited. This study aimed to determine the variegated leaf phenotype characteristics and their cause in P. ‘Sogo Vivien’. This study observed the anatomy of variegated leaves by comparing the green and white parts of the leaf, measured the concentration of chlorophyll pigments, and detected leaf starch content between both parts. In addition, polymorphism analysis was also performed on the VAR2 gene partial sequences. Based on leaf anatomy structure, the difference between variegated zones is only in the number of chloroplasts, the diameter of parenchyma cells, and chloroplasts. The chloroplast diameter within the white part is smaller than the green part. The chloroplasts’ diameters in the green part are two times larger than the white part, with four times more in amount. The two parts were formed due to differences in the distribution pattern of functional chloroplasts in the leaves. The concentration of chlorophyll in the green part is higher than in the white part, a characteristic of the chlorophyll-type variegation. The green parts have more starch grains than the white parts. Stomata distance between variegated zones on the abaxial side is different, and it was suggested as a distinctive character between variegated zones. A thymine insertion in exon 1 contributed to nonsense and missense mutations on the VAR2 gene isolated from the white part. This mutation caused the amino acid motif to change from KAKFQ to KA—Q. This mutation is suggested to cause the variegated leaf phenomenon in P. ‘Sogo Vivien’.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139557304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon observing the metabolic changes, it was found that the pear, sprayed MeJA, could keep higher the content of aroma, ascorbic acid, polyphenol, oleic acid, linoleic acid, and linolenic acid than the control, but stearic acid and H2O2 were decreased. The enzyme activities of lipoxygenase (LOX), alcohol acyl transferase (AAT), and catalase (CAT) were enhanced by MeJA treatment, but the polyphenol oxidase (PPO) was inhibited. Moreover, the gene expression levels of LOX, AAT, CAT, stearoyl-ACP desaturase (SAD), and fatty acid desaturase 2 (FAD2) were promoted by MeJA. It is reasonable that sprayed MeJA was a reliable method for inhibiting aroma loss and triggered unsaturated fatty acid and reactive oxygen metabolisms.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139515501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the interactional effects of water deficit and melatonin application on growth and physio-biochemical characteristics of basil were investigated. The treatments included three levels of irrigation (100, 75 and 50% of field capacity) and three melatonin concentrations (0, 50 and 100 µmol). Drought stress decreased the dry weight of plants but application of 100 µmol melatonin markedly increased dry weight under these conditions. Melatonin profoundly enhanced plant drought tolerance by stimulating the antioxidant enzymes (catalase, phenylalanine ammonia-lyase, ascorbate peroxidase and polyphenol oxidase) activities and secondary metabolites (total phenol, flavonoid and anthocyanin contents). Furthermore, melatonin application reduced lipid peroxidation and increased the relative water content and photosynthetic pigments, resulting in an improvement of plant dry matter. It is concluded that foliar spraying with melatonin induced the pre-adaptive responses to drought stress followed by regulating antioxidant defense mechanisms.","PeriodicalId":13123,"journal":{"name":"Horticulture Environment and Biotechnology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139497267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Z. jujuba cultivation has a long history, resulting in the creation of numerous cultivars, and the economic value of this plant has recently been on the rise. Therefore, there is a need for easy and accurate methods to distinguish the cultivars. We developed insertion or deletion (InDel) markers using chloroplast (CP) DNA to identify Z. jujuba cultivars.

The GA-treated fruits’ L* (lightness), a* (bluish-green/red-purple hue component), b* (yellow-blue hue component), and C* (chroma) values were significantly lower than those of non-GA-treated fruits.

Cracking assays confirmed that ‘Wanhongzhu’ was more susceptible to cracking than ‘Rainier’, with the T50 (the half time of fruit cracking in a given solution) of 5.53 and 22.27 h, respectively. During the storage, respiration rate, soluble solids content, titratable acid content, soluble protein content, ascorbic acid content, and firmness of ‘Wanhongzhu’ were higher than those of ‘Rainier’, but the color change and ethylene production were lower than those of ‘Rainier’. For the expression levels of cell wall metabolism-related genes, the expressions of Paβ-Gal, PaEXA4, PaaqpSIP2.1, and PaaqpPIP2.4 in ‘Wanhongzhu’ were higher than those of ‘Rainier’ during the storage, however, the expressions of PaPME, PaPEL.7, PaXTH, PaPAE.1, PaPOD and PaExp1 were lower than those of ‘Rainier’. Correlation analysis results suggest the expressions of cell wall metabolism-related genes in ‘Wanhongzhu’ had less effect on fruit quality than that in ‘Rainier’. Overall, compared with ‘Rainier’, ‘Wanhongzhu’ had better fruit quality during the low-temperature storage, but it was more likely to produce fruits cracking and rot, which shortens its shelf-life.
