Abstract:

Plants continuously produce damaged organelles and proteins in the process of growth and response to environmental stresses，which must be timely and appropriately degraded. Autophagy is a major cellular degradation pathway conserved during evolution in plants. Autophagosomes selectively recognize and target specific compartments and protein complexes through cargo receptor proteins，then deliver them to the vacuole for degradation and recycling，which regulates the critical reactions within the cell. Researches in recent years have revealed the importance of autophagy in many aspects of plant life. In this article，the latest advances of plant cell selective autophagy are reviewed，including autophagosome formation，cargo recognition and types of selective autophagy，and the role in growth and development，immune，and response to abiotic stress.

Key words: selective autophagy, protein degradation, cargo receptor, plant immune, abiotic stress
