摘　　要：细胞中存在种类繁多的无膜细胞器,在感知环境信号,基因表达调控,RNA加工等过程中发挥了重要的作用,而生物大分子相分离被证明是无膜细胞器形成的主要方式。文章介绍了生物大分子相分离的概念与特征,总结了有关相分离在植物对环境信号响应中的研究进展,并对相分离在植物中的生物学功能进行了分类,以期解析相分离在植物生长发育和逆境适应中的作用机理,揭示植物无膜细胞器的本质与功能。There are various types of membraneless organelles in cells,which play important roles in sensing environmental signals,regulating gene expression,RNA processing,etc..Biomolecular phase separation has been proven to be the main way of forming membraneless organelles.This article introduces the concept and characteristics of biomolecular phase separation,summarizes research progress of phase separation in plants response to environmental signals,and categorizes the biological functions of phase separation in plants in order to analyze the mechanisms by which phase separation plays a role in plant growth and development and adaptation to adversity,thereby to understand the natures and functions of plant membraneless organelles.
