摘 要:自噬(autophagy) 是一种存在于真核生物中进化保守的分解代谢过程,其最显著的特征是形成双层膜结构的自噬小泡(autophagosome)。细胞质内多余的或者已经损坏的成分被自噬小泡包裹,最终送入溶酶体或液泡进行降解并循环利用。随着自噬在动物和酵母中研究的不断深入,植物自噬得到人们越来越多的关注,其分子调控机理取得了诸多进展。现主要从细胞生物学角度总结近年来植物自噬研究中取得的成果,并对今后的研究方向及待解决的问题进行论述。
 
Cytological advances on plant autophagy

Abstract: Autophagy is a catabolic process that is evolutionarily conserved among eukaryotes. The prominent feature of autophagy is the formation of double membrane-bound vesicles, termed as autophagosomes. Unnecessary or damaged cytoplasmic components are engulfed by autophagosomes, and are finally delivered to lysosomes or vacuoles for breakdown and subsequent recycling. Similar to studies in animals and yeast, autophagy has become one of the hotspots in the field of plant biology and remarkable progress has been made in understanding the molecular mechanisms underlying this process. In this review, we summarize the recent cytological advances on plant autophagy and highlight the open questions and potential research directions.
