中文摘要：

细胞自噬是真核生物中广泛存在的过程，并且在进化上十分保守。在真核生物分化和发育的过程中，它参与胞内细胞器和蛋白质的周转，被认为在细胞的形态建成方面发挥重要作用。现就细胞自噬的分子机制和功能做一介绍，并对稻瘟病菌细胞自噬的研究现状进行了回顾。

英文摘要：

Autophagy is a ubiquitous and evolutionarily conserved process in eukaryotes. It has been presumed to be involved in cellular architectural changes that occur during differentiation and development, presumably via its roles in organelle and protein turnover. Here we review its molecular mechanism and functions. The further concerning research on rice blast fungus M. oryzae were been discussed as well.
