摘要
细胞自噬(autophagy)作为植物细胞维系稳态的一种重要代谢机制,主要通过双层膜结构的自噬小泡(autophagosome)包裹需降解物,随后将其传递至液泡进行降解并循环再利用。诸多研究表明,自噬在植物非生物逆境响应中发挥着重要作用。本文以高温胁迫、干旱胁迫为切入口,综述了近年来自噬在这两种逆境应答中的作用以及分子调控机制,以期为植物抗逆研究和分子育种提供参考。
Autophagy is an important catabolic process to maintain cellular homeostasis in plants. Autophagic process in plants initiates with production of double membrane vesicles, termed autophagosomes that engulf the cytoplasmic components and ultimately fuse with vacuoles for cargo degradation and subsequent recycling. Accumulating evidence indicates that autophagy plays a paramount role in plant abiotic stress responses. Here we summarize recent progress on the functions and regulatory mechanisms of autophagy in heat and drought stress responses, thereby providing a collection of references for future research in plant stress biology and molecular breeding.
