摘　　要：干旱胁迫严重影响着作物生长发育。主要从作物形态、渗透调节、光合作用、细胞膜及其结构的保护机制、干旱传感和信号转导、转录因子以及干旱诱导蛋白等方面对作物抗旱生理及其分子机制研究进展进行概述。以及对传统抗旱育种和现代分子抗旱育种作一简要概述。以期为我国抗旱农业研究与抗旱育种提供一些思路。Drought stress affects crop growth and development seriously. This paper introduces the research pro- gress of physiological and molecular mechanism of drought resistance in crop morphology, osmotic adjustment, photo- synthesis, cell membrane and its structure protection mechanisms, drought sensing and signal transduction, transcrip- tion factors and drought induced proteins. As well as brief overview of the conventional and modern molecular breed- ing for drought resistance is done, which could supply several new approaches to agricultural research and breeding of drought resistance in China.
