基因组组织成核小体和更高级的染色质结构对基因表达的调控具有深远的意义。DNA复制与修复染色质的结构可以通过几种机制重塑;其中，核小体组装/拆卸和用组蛋白变体替换典型组蛋白构成重要机制。本文综述了拟南芥中组蛋白分子伴侣参与核小体组装/拆卸和基因突变的研究进展。本文讨论了组蛋白分子伴侣、核小体组装/拆卸和组蛋白变异体在植物非生物胁迫响应中的重要作用。染色质结构重塑可能为植物基因转录调控提供一种灵活、全面和稳定的手段，帮助植物更有效地科普环境胁迫。这篇文章是特刊的一部分，题为：组蛋白伴侣和染色质组装。(C)2011 Elsevier B. V.保留所有权利。
Genome organization into nucleosomes and higher-order chromatin structures has profound implications for the regulation of gene expression. DNA replication and repair. The structure of chromatin can be remodeled by several mechanisms; among others, nucleosome assembly/disassembly and replacement of canonical histones with histone variants constitute important ones. In this review, we provide a brief description on the current knowledge about histone chaperones involved in nucleosome assembly/disassembly and hit tone variants in Arabidopsis thaliana. We discuss recent advances in revealing crucial functions of histone chaperones, nucleosome assembly/disassembly and histone variants in plant response to abiotic stresses. It appears that chromatin structure remodeling may provide a flexible, global and stable means for the regulation of gene transcription to help plants more effectively cope with environmental stresses.
