Abstract
Histone chaperones and histone variants play crucial roles in DNA replication, gene transcription, and DNA repair in eukaryotes. Histone chaperones reversibly promote nucleosome assembly and disassembly by incorporating or evicting histones and histone variants to modulate chromatin accessibility, thereby altering the chromatin states and modulating DNA-related biological processes. Cofactors assist histone chaperones to target specific chromatin regions to regulate the exchange of histones and histone variants. In this review, we summarize recent progress in the interplay between histone variants and chaperones in plants. We discuss the structural basis of chaperone–histone complexes and the mechanisms of their cooperation in regulating gene transcription and plant development.
组蛋白伴侣和组蛋白变体在真核生物的 DNA 复制、基因转录和 DNA 修复中发挥着至关重要的作用。组蛋白伴侣通过结合或驱逐组蛋白和组蛋白变体，可逆地促进核小体的组装和解体，从而调节染色质的可及性，改变染色质状态，调节与 DNA 相关的生物过程。辅助因子协助组蛋白伴侣以特定染色质区域为目标，调节组蛋白和组蛋白变体的交换。在这篇综述中，我们总结了植物中组蛋白变体与伴侣蛋白之间相互作用的最新进展。我们讨论了伴侣-组蛋白复合物的结构基础以及它们在调控基因转录和植物发育方面的合作机制。
