Plants and plant-associated microorganisms including phytopathogens have to adapt to drastic changes in environmental conditions. Because of their immobility, plants must cope with various types of environmental stresses such as starvation, oxidative stress, drought stress, and invasion by phytopathogens during their differentiation, development, and aging processes. Here we briefly describe the early studies of plant autophagy, summarize recent studies on the molecular functions of ATG genes, and speculate on the role of autophagy in plants and phytopathogens. Autophagy regulates senescence and pathogen-induced cell death in plants, and autophagy and pexophagy play critical roles in differentiation and the invasion of host cells by phytopathogenic fungi.
植物和植物相关的微生物，包括植物病原体，必须适应环境条件的剧烈变化。由于它们不能移动，植物在其分化、发育和衰老过程中必须应对各种类型的环境胁迫，如饥饿、氧化应激、干旱胁迫和植物病原体的入侵。在这里，我们简要描述了植物自噬的早期研究，总结了最近关于 ATG 基因分子功能的研究，并推测了自噬在植物和植物病原体中的作用。自噬调节植物的衰老和病原体诱导的细胞死亡，自噬和过氧化物酶体自噬在植物病原体真菌的分化和宿主细胞的入侵中起着关键作用。
