盐害是制约全世界作物生长的主要非生物胁迫之一，全球有6%土地和20%灌溉用地受到盐害影响，严重制约了农作物生长发育和产量。水稻作为全球主要粮食作物之一，对盐胁迫敏感。盐胁迫条件下，水稻种子萌发和幼苗形态建成显著受抑制，严重制约了我国水稻直播的推广和盐碱地区耕地利用。因此，挖掘鉴定控制水稻种子萌发的关键基因，阐明其在盐胁迫条件下调控种子活力的分子机制，对培育适合盐碱地生长的种子高活力耐盐水稻品种和保...
团队全面系统论述了植物激素脱落酸（ABA）在种子的成熟、休眠和萌发过程中的最新研究进展，总结了脱落酸通过含量变化和信号转导的调节来参与种子发育不同阶段的分子机制，提出了脱落酸与其他不同的激素、代谢物质等信号分子互作调控种子发育的模式图，对于揭示脱落酸介导的种子发育过程的分子调控网络具有重要意义。
