摘要

摘要植物的生长发育及其对生物和非生物胁迫的反应受复杂的基因和蛋白质调控网络的支配,其中表观遗传修饰酶起着至关重要的作用。组蛋白赖氨酸乙酰化水平受组蛋白乙酰转移酶(HATs)和组蛋白去乙酰化酶(HDACs)的调控,在转录调控领域得到了深入研究。然而,先进的蛋白质组学技术的出现揭示了非组蛋白也会发生乙酰化,其潜在机制也正在被阐明。事实上,非组蛋白乙酰化通过多种途径影响蛋白质的功能,如调节蛋白质稳定性、调整酶活性、引导亚细胞定位、影响与其他翻译后修饰的相互作用,以及管理蛋白质-蛋白质和蛋白质-DNA 之间的相互作用。本综述深入探讨了植物非组蛋白乙酰化功能机制的最新见解。我们还总结了 HATs 和 HDACs 在水稻和拟南芥中的作用,并探讨了它们参与非组蛋白调控的可能性。

Advances in understanding the roles of plant HAT and HDAC in non-histone protein acetylation and deacetylation

Advances in understanding the roles of plant HAT and HDAC in non-histone protein acetylation and deacetylation

Main conclusion

This review focuses on HATs and HDACs that modify non-histone proteins, summarizes functional mechanisms of non-histone acetylation as well as the roles of HATs and HDACs in rice and Arabidopsis.

Abstract

The growth and development of plants, as well as their responses to biotic and abiotic stresses, are governed by intricate gene and protein regulatory networks, in which epigenetic modifying enzymes play a crucial role. Histone lysine acetylation levels, modulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs), are well-studied in the realm of transcriptional regulation. However, the advent of advanced proteomics has unveiled that non-histone proteins also undergo acetylation, with its underlying mechanisms now being clarified. Indeed, non-histone acetylation influences protein functionality through diverse pathways, such as modulating protein stability, adjusting enzymatic activity, steering subcellular localization, influencing interactions with other post-translational modifications, and managing protein–protein and protein–DNA interactions. This review delves into the recent insights into the functional mechanisms of non-histone acetylation in plants. We also provide a summary of the roles of HATs and HDACs in rice and Arabidopsis, and explore their potential involvement in the regulation of non-histone proteins.
