Epigenetic activation of auxin signaling: coordinated CHH hypomethylation and histone modifications promote bud dormancy release in tea plants

Sprouting of overwintering buds is an important biological process in tea plants (Camellia sinensis) that determines spring shoot yield and economic benefits. Epigenetic modifications, such as DNA methylation and histone marks, regulate plant growth and development; however, their precise mechanisms in tea dormancy release remain unclear. This study aimed to highlight how epigenetic auxin (IAA) coordination regulates developmental phase transition. To this end, the distinct dormancy phases of te
