Tóm tắt

Bud dormancy is a crucial mechanism that allows perennial woody plants to withstand adverse environmental conditions, and gibberellin (GA) typically promotes the dormancy release of buds. DELLA protein is the core factor in the GA signaling pathway. This study identified 11 VcDELLA genes from the blueberry genome and performed a comprehensive bioinformatics analysis and prediction of the VcDELLA gene family. GA not only inhibits the dormancy entry of blueberry flower buds under low temperature and short-day conditions but also promotes the dormancy release of flower buds. During the dormancy release process, exogenous GA
