Abstract: Freezing is a major environmental stress to the plants growing from subtropical regions to frigid areas,and the plants have successfully evolved the strategy to vurvive the low temperature encountered. In recent years,the cold-adaptation strategy of plants has been widely studied at physiological and molecular levels i.e.,there have been certain understandings on the cold signal transduction network,types and fucntions of cold-induced genes. But the physiological characteristics and survival strategies of chloroplasts in overwintering plant during cold stress,still largely remain unknown. In the current review,we collected and compiled the reported information on the cold damages,cold-signal transduction and cold-adaptation strategy of plant chloroplasts,aiming at being conducive to the researches of this field.

Key words: chloroplast, freezing injury, cold acclimation, cold signal transduction
