Abstract
Heterochromatin is a nuclear area that contains highly condensed and transcriptionally inactive chromatin. Alterations in the organization of heterochromatin are correlated with changes in gene expression and genome stability, which affect various aspects of plant life. Thus, studies of the molecular mechanisms that regulate heterochromatin organization are important for understanding the regulation of plant physiology. Microscopically, heterochromatin can be characterized as chromocenters that are intensely stained with DNA-binding fluorescent dyes. Arabidopsis thaliana exhibits distinctive chromocenters in interphase nuclei, and genetic studies combined with cytological analyses have identified a number of factors that are involved in heterochromatin assembly and organization. In this review, I will summarize the factors involved in the regulation of heterochromatin organization in plants.
异染色质是一个包含高度浓缩且转录不活跃的染色质的核区域。异染色质组织的变化与基因表达和基因组稳定性的变化相关，而基因表达和基因组稳定性的变化会影响植物生命的各个方面。因此，研究调控异染色质组织的分子机制对于了解植物生理调控非常重要。在显微镜下，异染色质的特征是染色中心被 DNA 结合荧光染料强烈染色。遗传学研究结合细胞学分析发现了许多参与异染色质组装和组织的因子。在这篇综述中，我将总结参与植物异染色质组织调控的因子。
期刊介绍：
The Journal of Plant Research is an international publication that gathers and disseminates fundamental knowledge in all areas of plant sciences. Coverage extends to every corner of the field, including such topics as evolutionary biology, phylogeography, phylogeny, taxonomy, genetics, ecology, morphology, physiology, developmental biology, cell biology, molecular biology, biochemistry, biophysics, bioinformatics, and systems biology.
The journal presents full-length research articles that describe original and fundamental findings of significance that contribute to understanding of plants, as well as shorter communications reporting significant new findings, technical notes on new methodology, and invited review articles.
