摘　　要：The biosynthesis and signaling of plant hormones play a critical role in almost all biological processes.It is well-documented that phytohormones cross-talk with each other.Epigenetic mechanisms were suggested to regulate expression of downstream targets in hormone signaling pathways that help implement hormone functions.This new layer of complexities that integrate epigenetic information such as DNA methylation,chromatin remodeling,histone modification,microRNAs and siRNAs with plant hormone signaling and regulations of gene expression,has been gradually revealed.In this short review,the author tries to assemble recent progress to establish a molecular linkage between these two large and momentum research fields and also to help readers digest the literature.The biosynthesis and signaling of plant hormones play a critical role in almost all biological processes.
