摘要: 低温冷冻是亚热带至寒带地区植物要经受的一种主要环境胁迫,而生活于这些地区的越冬植物经过长期进化已经产生了适应低温环境的策略。近年来人们从生理到分子的多个水平对植物适应低温环境的策略进行了研究,对低温的信号转导、冷诱导基因的类别和功能机制都有了一定的认识。但是,对越冬植物细胞中叶绿体这一重要结构在低温下的生理活动特点和生存策略的认识还不多。搜集整理了近年来的研究文献中对叶绿体的低温损伤、低温信号转导和低温适应策略的资料,以期助力于该领域的研究。

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
