Abstract

Abstract : Grape berry development is a highly coordinated and intricate process. Herein, we analyzed the phenotypic and transcriptomic patterns of Victoria (VT) and Flame Seedless (FS) grape varieties during berry development. Physiological analysis and transcriptomic sequencing were performed at four berry developmental phases. VT berry size was comparatively larger to the FS variety. At maturity, 80 days postanthesis (DPA), the FS soluble solids were 61.8% higher than VT. Further, 4889 and 2802 differentially expressed genes were identified from VT and FS 40 DPA to 80 DPA development stages, respectively. VvSWEET15, VvHXK, and MYB44 genes were up‐regulated during the postanthesis period, while bHLH14, linked to glucose metabolism, was gradually down‐regulated during berry development. These genes may have significant roles in berry development, ripening, and sugar accumulation. Abstract : Grape berry development is a highly coordinated process. Herein, phenotypic and transcriptomic patterns of Victoria and Flame Seedless varieties were analyzed during berry development. Physiologically, VT berry size was larger than the FS variety, but FS contained higher levels of soluble solids at maturity. Furthermore, we examine genes that have significance in berry development, ripening, and sugar accumulation for the two varieties.
