【摘要】 对有关逆境响应基因的最新进展作了一简要的综述．在逆境条件下，脱落酸（ＡＢＡ）浓度增加，诱导许多新的基因表达及蛋白质合成．已克隆到几百种逆境响应基因，其中大多数可受外源ＡＢＡ的诱导．对这些基因及蛋白质的功能已有所了解，认为它们可能与植物的抗逆能力有关．目前认为有多条信号传递途径参与胁迫信号的转导更多还原

【Abstract】 Many new genes and proteins are induced under stress environment, following the increasing concentration of the abscisic acid. Up to now, hundreds of ABAresponsive genes have been cloned and most of them can be induced by exogenous ABA, these genes expression products are deduced to play an important role in the gain of stress tolerance. As to the stress signal transduction, it is considered that there may be multiple pathways and regulation mechanisms to be involved. The recent progress is briefly summarized about the ABAresponsive genes.更多还原
