| 摘 要： | 干旱、高盐、极端温度等逆境因子是限制作物产量和品质提高的重要因素.挖掘和利用逆境应答基因资源是改良其抗逆性的前提和基础,对于研究植物抗逆机制具有重要意义.蔗糖非发酵相关蛋白激酶家族2（Sucrose non-fermenting-1-related protein kinase 2,SnRK2）是广泛存在于植物中的一类Ser/Thr蛋白激酶,参与植物体内多种信号途径的转导,在植物的抗逆境生理过程中扮演了重要角色.为了促进小麦SnRK2基因家族的研究,该文对SnRK2基因的结构、抗逆功能、互作蛋白,以及小麦SnRK2基因家族的研究现状进行了阐述.

| Abstract: | Drought,salinity and low temperatures are major factors limiting tobacco productivity and quality.To survive adverse stresses,plants have developed complex signaling networks to perceive external stimuli,and then manifest adaptive responses at molecular and physiological levels.Mining and deployment of these genetic resources are the foundations for improving the drought resistance in wheat （Triticum aestivum L.）.Sucrose non-fermenting-1-related protein kinase 2 （SnRK2） is a class of Ser/Thr protein kinase widely existing in plant and involved in a variety of signaling pathways,which play a pivotal role in plant stress physiology.To promote the study of SnRK2 kinase,the current plant and wheat SnRK2s studies,including sequence structure,function of stress resistance,and interacting proteins will be reviewed in this paper. |
