| 摘 要： | 脱水素是LEA蛋白中的一类,广泛存在于植物的各个组织器官及植物胚胎发育后期.脱水素是植物在受低温、干旱和高盐等非生物逆境胁迫时合成的一类高亲水性保护蛋白,具有保护核酸、胞内蛋白和膜结构免受损害的功能.许多研究已经证实在非生物胁迫下,植物脱水素的表达与积累和植物抗逆性之间存在着紧密的联系.对脱水素的结构、亚细胞定位、基因表达模式及非生物胁迫下脱水素作用的最新研究成果进行了综述.

| Abstract: | Dehydrins, known as a group of late embryogenesis abundant （LEA） proteins, are present in all plant organs and during late embryogenesis. Dehydrins have extremely hydrophilieity and are produced to protect plants from structural and molecular damage caused by abiotie stresses like low temperature, drought and salt stress. The positive correlation between the accumulation of dehydrin and abiotic stress tolerance in plants was reported. This review summarized the current knowledge about the structural characters, subcellular localization and gene expression of dehydrins and the functions in plant stress tolerance. |
