摘要

与Set1相关的蛋白质复合物（COMPASS）复合物代表了一组高度保守的多亚基复合物，在真核生物物种中催化组蛋白H3赖氨酸4甲基化。在果蝇和哺乳动物中，COMPASS复合物被分为不同的亚型，其亚基组成决定了其不同的功能。植物也进化出类似的COMPASS组件，它们同样表现出功能多样化，在调节营养生长、开花转变和逆境适应方面发挥多效作用。近年来的研究极大地促进了我们对植物COMPASS的组成、染色质靶向和生物学功能的了解。本文综述了COMPASS在几种植物中保守的核心成分、染色质靶向策略、与其他表观遗传标记的串扰以及COMPASS在逆境适应中的调控作用。我们还讨论了可能为作物改良提供线索的研究。

Complex of Proteins Associated with Set1 complexes and their increasing roles in crop improvement

The Complex of Proteins Associated with Set1 (COMPASS) complexes represent a group of highly conserved, multi-subunit complexes that catalyze histone H3 lysine 4 methylation across eukaryotic species. In Drosophila and mammals, COMPASS complexes are classified into distinct subtypes with diverse functions determined by their subunit composition. Plants have evolved analogous COMPASS assemblies that similarly exhibit functional diversification, playing pleiotropic roles in regulating vegetative growth, flowering transition, and stress adaptation. Recent studies have significantly advanced our understanding of the composition, chromatin targeting, and biological functions of plant COMPASS. In this review, we summarize the conserved core components of COMPASS in several plant species, the chromatin targeting strategies, crosstalk with other epigenetic marks, and regulatory role of COMPASS in stress adaptation. We also talk about the researches that may provide clues for crop improvement.
