摘要：
The plant hormone abscisic acid (ABA) accumulates in tea leaves under dehydration stress during the withering process. However, the mechanism underlying ABA biosynthesis regulation remains largely unclear. In the present study, we found increased expression of ABA biosynthesis genes under dehydration stress during postharvest processing of tea. Furthermore, dehydration stress promoted ABA accumulation by increasing histone acetylation of ABA anabolism genes but by decreasing the levels of histone H3 lysine 9 dimethylation and DNA methylation of ABA biosynthesis genes. We screened candidate regulators of histone deacetylation and DNA methylation under dehydration stress. Taken together, our results indicate a role for epigenetic modifications during postharvest processing of tea.
