玉米Wiltedx突变体的初步研究及基因克隆

【摘 要】
：
植物抗旱性研究是比较老的研究课题,但是,植物受到水分胁迫时会引起一系列的生理生化变化和形态结构的改变,涉及到许多基因的调控,所以,植物抗旱性是一个相当复杂的问题.玉米是旱地作物中需水量最大,对水分胁迫很敏感的作物之一,在其生育期内至少需要2500mm的降水量.在以往的玉米抗旱研究中,人们都是通过干旱处理或高渗培养液模拟干旱条件,很多研究结果都不太一致,这可能是不同研究者干旱处理或高渗培养液模拟干旱

植物抗旱性研究是比较老的研究课题,但是,植物受到水分胁迫时会引起一系列的生理生化变化和形态结构的改变,涉及到许多基因的调控,所以,植物抗旱性是一个相当复杂的问题.玉米是旱地作物中需水量最大,对水分胁迫很敏感的作物之一,在其生育期内至少需要2500mm的降水量.在以往的玉米抗旱研究中,人们都是通过干旱处理或高渗培养液模拟干旱条件,很多研究结果都不太一致,这可能是不同研究者干旱处理或高渗培养液模拟干旱的条件存在很大误差.
