“…TSS is an important index for the evaluation of taste quality of grape. The sugars (mainly glucose and fructose in grape berry) are essential for maintaining the basic function of the fruit, and contributing to its taste [41,42]. However, phenolic compounds play important roles in the appearance of fruits [1].…”

Low temperature storage is widely used to maintain the postharvest quality of table grape. However, grape clusters easily undergo deterioration without treatment during the storage time. The main goal of this study was to evaluate the effect of postharvest 1-methylcyclopropene (1-MCP), calcium chloride (1%) and ethanol (16%), and the combination of 1-MCP with calcium chloride and ethanol treatments on maintenance of quality of table grapes ‘Kyoho’ (Vitis vinifera × Vitis labrusca) under 5 °C and 0 °C storage. Changes in decay incidence, weight loss, rachis browning and quality indexes of grape clusters were investigated. The results were as follows: all treatments significantly reduced the decay incidence, weight loss, rachis browning at both low temperatures storage; 1-MCP had positive effect for reducing the decay incidence in early stage, but no effect in late stage; there are no significant variations of taste and color quality indexes under two low temperatures storage, regardless of the treatments. Overall findings suggested that the combination of 1-MCP with calcium chloride and ethanol treatment is suitable for short-term 0 °C storage, while for long-term 0 °C storage, calcium chloride (1%) and ethanol (16%) treatment should be selected.

“…As one of the most common physiological disorders that happened in citrus fruit, juice sac granulation had many adverse effects on fruit quality, which had been a concern by the producer and researchers for a long time. The granulated juice sacs have increased firmness ( Chen et al, 2021 ), lower soluble sugars and organic acids contents ( Shomer et al, 1989 ; Sharma et al, 2006 ; Wang et al, 2014 ), while higher cell wall components contents, including pectin, cellulose, and lignin ( Yao et al, 2018 ; Cao et al, 2020 ; Shi et al, 2020 ). In addition, the main volatile compounds, such as limonene and β-myrcene, were dramatically decreased in the granulated juice sac ( Cao et al, 2020 ; Yao et al, 2020 ).…”

Juice sac granulation is a common internal physiological disorder of citrus fruit. In the present study, we compared the physiochemical characteristics and transcriptome profiles of juice sacs in different granulation levels from Huyou fruit (Citrus changshanensis). The accumulation of cell wall components, including the water-soluble pectin, protopectin, cellulose, and lignin, were significantly correlated with the granulation process, resulting in the firmness increase of the juice sac. The in situ labeling of the cell wall components indicated the early accumulation of cellulose and high-methylesterified pectin in the outer layer cells, as well as the late accumulation of lignin in the inner layer cells of the juice sac. Several phytohormones, including auxins, abscisic acids, cytokinins, jasmonic acid, salicylic acid, and/or their metabolites, were positively correlated to the granulation level, indicating an active and complex phytohormones metabolism in the granulation process. Combining the trend analysis by the Mfuzz method and the module-trait correlation analysis by the Weighted Gene Co-expression Network Analysis method, a total of 2940 differentially expressed genes (DEGs) were found to be positively correlated with the granulation level. Gene Ontology (GO) enrichment indicated that the selected DEGs were mainly involved in the cell wall organization and biogenesis, cell wall macromolecule metabolic process, carbohydrate metabolic process, and polysaccharide metabolic process. Among these selected genes, those encoding β-1,4-xylosyltransferase IRX9, cellulose synthase, xyloglucan: xyloglucosyl transferase, xyloglucan galactosyltransferase MUR3, α-1,4-galacturonosyltransferase, expansin, polygalacturonase, pectinesterase, β-glucosidase, β-galactosidase, endo-1,3(4)-β-glucanase, endoglucanase and pectate lyase that required for the biosynthesis or structural modification of cell wall were identified. In addition, NAC, MYB, bHLH, and MADS were the top abundant transcription factors (TFs) families positively correlated with the granulation level, while the LOB was the top abundant TFs family negatively correlated with the granulation level.

Agrobacterium-mediated transformation of epicotyl segment has been used in Citrus transgenic studies. The approach suffers, however, from limitations such as occasionally seed unavailability, the low transformation efficiency of juvenile tissues and the high frequency of chimeric plants. Therefore, a suspension cell culture system was established and used to generate transgenic plants in this study to overcome the shortcomings. The embryonic calli were successfully developed from undeveloped ovules of the three cultivars used in this study, “Sweet orange”-Egyptian cultivar (Citrus sinensis), “Shatangju” (Citrus reticulata) and “W. Murcott” (Citrus reticulata), on three different solid media. Effects of media, genotypes and ages of ovules on the induction of embryonic calli were also investigated. The result showed that the ovules’ age interferes with the callus production more significantly than media and genotypes. The 8 to 10 week-old ovules were found to be the best materials. A cell suspension culture system was established in an H+H liquid medium. Transgenic plants were obtained from Agrobacterium-mediated transformation of cell suspension as long as eight weeks subculture intervals. A high transformation rate (~35%) was achieved by using our systems, confirming BASTA selection and later on by PCR confirmation. The results demonstrated that transformation of cell suspension should be more useful for the generation of non-chimeric transgenic Citrus plants. It was also shown that our cell suspension culture procedure was efficient in maintaining the vigor and regeneration potential of the cells.
