茶树在生长发育和采后加工过程中受到多重胁迫，影响叶片中次生代谢物的含量，影响茶叶的功能特性和品质。关于茶叶次生代谢的研究大多集中在基因、蛋白质和代谢物水平上，而上游调控机制尚不清楚。本文以DNA甲基化和组蛋白乙酰化为例，总结了表观遗传修饰对植物次生代谢的重要调控作用，并讨论了可行的研究策略，以阐明茶叶次生代谢调控潜在的特定表观遗传机制。这些信息将有助于研究人员研究茶叶次生代谢的表观遗传调控，为未来的茶叶遗传育种提供关键的表观遗传学数据。
Tea plants are subjected to multiple stresses during growth, development, and postharvest processing, which affects levels of secondary metabolites in leaves and influences tea functional properties and quality. Most studies on secondary metabolism in tea have focused on gene, protein, and metabolite levels, whereas upstream regulatory mechanisms remain unclear. In this review, we exemplify DNA methylation and histone acetylation, summarize the important regulatory effects that epigenetic modifications have on plant secondary metabolism, and discuss feasible research strategies to elucidate the underlying specific epigenetic mechanisms of secondary metabolism regulation in tea. This information will help researchers investigate the epigenetic regulation of secondary metabolism in tea, providing key epigenetic data that can be used for future tea genetic breeding.
