Abstract

Histone acetylation regulates gene transcription by chromatin modifications and plays a crucial role in the plant development and response to environment cues. The homeostasis of histone acetylation is controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs) in different plant tissues and development stages. The vigorous knowledge of the function and co-factors about HATs (e.g. GCN5) and HDACs (e.g. HDA19, HDA6) has been obtained from model plant Arabidopsis. However, understanding individual role of other HATs and HDACs require more work, especially in the major food crops such as rice, maize and wheat. Many co-regulators have been recently identified to function as a component of HAT or HDAC complex in some specific developmental processes. The described findings show a distinctive and interesting epigenetic regulation network composed of HATs, HDACs and co-regulators playing crucial roles in the seed performance, flowering time, plant morphogenesis, plant response to stresses etc. In this review, we summarized the recent progresses and suggested the perspective of histone acetylation research, which might provide us a new window to understand the epigenetic code of plant development and to improve the crop production and quality.
