摘要
综述了植物应答干旱胁迫的基因表达调控研究及干旱基因工程方面的研究进展。干旱是植物生长发育过程中经常遇到的最严重的非生物胁迫之一。当植物遭遇干旱逆境时,细胞迅速感知外界信号,通过信号转导进而激活许多干旱胁迫应答基因的表达,在植物体内产生大量的特异蛋白,协同调节植物生理生化以及代谢的变化,从而提高植物对干旱的耐性。
This paper mainly reviewed regulation of gene expression involved in response to drought and genetic engineering of drought tolerant crops. Drought is one of the most severe ahiotic stresses in plant growth and development. The major events of plant response to drought stress are perception and transduction of the stress signals through signaling components, resulting in activation of a large number of stress-related genes and synthesis of diverse functional proteins that coordinately regulate various physiological and metabolic responses.
