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。

植物花冠和果实的颜色是长期自然选择的结果，受到虫媒、掠食动物以及环境因素的影响。黄色花冠是一种重要的植物信号，在保障虫媒传粉植物的正常繁殖过程中具有举足轻重的作用。许多重要的农作物，包括番茄和油菜等十字花科植物，具有金黄色的花朵，花色主要由类胡萝卜素积累导致，且类胡萝卜素还广泛存在于橙色和黄色的蔬菜和水果中，如南瓜、甜椒、芒果、橙子等。植物通过何种机制保证自己开黄花呢？
