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.

浆果成熟过程中维多利亚和火焰无核葡萄品种的比较表型和转录组学分析

葡萄浆果的发育是一个高度协调和复杂的过程。在此，我们分析了维多利亚 (VT) 和火焰无籽 (FS) 葡萄品种在浆果发育过程中的表型和转录组模式。在四个浆果发育阶段进行生理分析和转录组测序。VT 浆果大小比 FS 品种大。在成熟期，即开花后 80 天 (DPA)，FS 可溶性固体比 VT 高 61.8%。此外，分别从 VT 和 FS 40 DPA 到 80 DPA 发育阶段鉴定了 4889 和 2802 个差异表达基因。VvSWEET15、VvHXK 和 MYB44 基因在花后期间上调，而与葡萄糖代谢相关的 bHLH14 在浆果发育期间逐渐下调。这些基因可能在浆果发育、成熟、
