摘要

Persimmon is a popular food around our country. The nutrient composition profiles and dynamics of gene expression in persimmon are poorly understood till now. Our research found total soluble sugar, fructose and glucose accumulated gradually, and tannin content decreased during the persimmon ripening. Furthermore, we analyzed the temporal transcriptome data and identified the transcriptional changes during persimmon fruit development. Incredibly, 232 WRKY, 143 bHLH, 112 MYB, and 102 C2H2 were explicitly differentially expressed in five typical development stages of persimmon. Specifically, 11 condensed tannins (procyanidins) biosynthesis-related gene expressions analysis, and 13 critical genes, involved in starch and sucrose metabolism were identified. Our results provide insights into gene networks during Persimmon fruit development and generate a valuable resource for further Persimmon breeding studies.
