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？

刘建祥 生物钟基因调控 环境温度 植物进化 耦合机制
2022/10/12
全球气候变暖和极端高温严重威胁着植物的生长发育以及农作物的产量和品质。为响应外界温度的变化，植物进化出复杂的生物钟系统调控植物的生长发育及新陈代谢，然而生物钟相关基因如何协调环境温度和植物生长发育的分子机制仍知之甚少。2022年8月31日，浙江大学生命科学学院刘建祥课题组在New Phytologist上在线发表了题为A competition-attenuation mechanism modu...
