细胞自噬在植物碳氮营养中作用的研究进展

Progress on the Involvement of Plant Autophagy in Carbon and Nitrogen Utilization

自噬(autophagy)是真核生物细胞通过形成自噬体,回收利用胞内物质,维持细胞健康的高通量亚细胞降解途径。随着酵母和动物自噬研究的深入,植物自噬也受到越来越多的关注。近期的研究揭示了植物自噬的基本机制及其生理意义,也发现了植物特有的自噬形式与自噬相关基因。该文主要综述了自噬在植物碳、氮营养中的作用。

Autophagy is a bulk degradation pathway of eukaryotic cells that contributes to nutrient recycling and health maintenance. Similar to studies in yeasts and animals, autophagy has become an important topic in plant biology. Recent studies have established the basic mechanism of plant autophagy, and the multi- faceted functions of autophagy in plant life have been revealed. Moreover, unique forms of plant autophagy and new genes have been discovered. This article reviews recent findings on the involvement of autophagy in plant carbon and nitrogen utilization.
