中文摘要：
干旱是造成作物减产的主要逆境之一。本项目通过水稻突变体库和资源的干旱筛选、利用遗传和功能基因组分析等多综合途径，分离了一批干旱胁迫起调控作用的关键基因并进行了深入的功能分析，克隆和功能鉴定10多个参与信号接受和传递的关键基因或对干旱胁迫起调控作用的关键转录因子基因（SNAC1，SNAC2，SN1,SN28,SNTG1，GTalpha-1,OsbZIP23,OsbZIP46, OsbZIP72,OXHS4,TIFY11a, TITY11b）。鉴定出1条通过SNAC1-SNTG1-DST-H2O2的调控气孔关闭的途径，以及一条以ABA-OsbZIP23-BIP4的ABA应答调控途径，均对抗旱起关键作用。通过本项目研究发现至少4个有抗旱育种价值的新基因（SNAC1，OsbZIP23，OsSKIPa，DSM2）。
