小分子热激蛋白参与植物抗逆性方面的研究进展
|
摘要
小分子热激蛋白(sHSPs)是植物面临逆境胁迫时,被激活且表达增强的一类蛋白,属于热激蛋白的一个亚家族。sHSPs作为分子伴侣,在植物抵抗高温热害、低温冷害以及种子发育中具有重要的作用。综述了sHSPs的分类、特点和功能,重点讲述了其参与植物抗逆性方面的研究进展,对目前研究中存在的问题进行了讨论,并对今后的研究方向进行了展望。
sHSPs,a subfamily of heat shock proteins,are activated and highly expressed when plants exposed to adverse stresses.As a molecular chaperone,sHSPs play crucial roles in the resistance of heat,cold and seed development.The classification,characteristics and function were reviewed,especially the role in plant resistance.And related problems in the current study were discussed and the future research fields were prospected.
