摘　　要：糖在植物中不仅用于能量代谢,也对植物生长发育、代谢调控及抵抗胁迫等具有重要调节作用。文章对植物在低温胁迫中糖积累的作用、影响糖积累的相关酶变化、外源ABA对低温胁迫下糖代谢影响等研究进展进行综述。展望植物抗寒研究,从基因、转录、蛋白及代谢等组学整体水平上探讨糖代谢应答低温胁迫及糖作为信号分子参与调控机制。Sugar in plants had many effects not only on energy metabolism, but also on the growth and development of plants, metabolic regulation and tolerance to stress. Effects of sugar accumulation, changes of related enzymes affecting sugar accumulation and exogenous ABA on sugar metabolism in plants under low temperature stress were reviewed. The mechanism of sugar metabolism response to cold stress and glucose as a signaling molecule could be studied from the genome, transcriptome, proteomics and metabonomics level.
