南京农业大学农学院《New Phytologist》发表植物环境适应分子遗传研究课题组“A major gene for chilling tolerance variation in Indica rice codes for a kinase OsCTK1 that phosphorylates multiple substrates under cold”（图）
植物环境 分子遗传
2024/4/29
水稻起源于热带和亚热带，对低温十分敏感，当温度低于15℃时水稻便无法正常生长。有统计显示，每年低温冷害导致我国水稻减产约50亿kg。近年来，因直播稻大面积推广以及水稻种植区域不断由热带、亚热带向高海拔、高纬度地区扩张，水稻遭受低温冷害的频率有增加趋势。低温冷害已成为限制我国水稻生产的一大瓶颈。因此，挖掘调控水稻耐冷性的关键基因，研究其作用机理，对防控水稻低温冷害具有重要意义。
