摘　　要：Chloroplasts are unique organelles that not only provide sites for photosynthesis and many metabolic processes,but also are sensitive to various environmental stresses.Chloroplast proteins are encoded by genes from both nuclear and chloroplast genomes.During chloroplast development and responses to stresses,the robust protein quality control systems are essential for regulation of protein homeostasis and the integrity of chloroplast proteome.In this review,we summarize the regulatory mechanisms of chloroplast protein degradation refer to protease system,ubiquitin-proteasome system,and the chloroplast autophagy.These mechanisms symbiotically play a vital role in chloroplast development and photosynthesis under both normal or stress conditions.
