摘要
干旱是影响农业生产最严重的自然灾害。干旱胁迫下,植物的蛋白激酶(如MAPK)介导的信号途径活化,引起相应的干旱胁迫信号转导,并最终诱导响应干旱基因的表达,使植物产生抗旱性。植物体内响应干旱的基因主要编码早期表达为转录因子和受转录因子调控的抗旱功能蛋白。
Drought stress is the most important abiogenetic factor that affects plant productivity in the world. Drought stress activates several protein kinases including mitogen-activated kinases（MAPK）, which may induce related signal transduction and thus regulate gene expression in response to drought stress .Responsive genes to drought stress include early response transcriptional activators and downstream stress tolerance effector genes.
