When exposed to warmer, nonstressful average temperatures, some plant organs grow and develop at a faster rate without affecting their final dimensions. Other plant organs show specific changes in morphology or development in a response termed thermomorphogenesis. Selected coding and noncoding RNA, chromatin features, alternative splicing variants, and signaling proteins change their abundance, localization, and/or intrinsic activity to mediate thermomorphogenesis. Temperature, light, and circadian clock cues are integrated to impinge on the level or signaling of hormones such as auxin, brassinosteroids, and gibberellins. The light receptor phytochrome B (phyB) is a temperature sensor, and the phyB–PHYTOCHROME-INTERACTING FACTOR 4 (PIF4)–auxin module is only one thread in a complex network that governs temperature sensitivity. Thermomorphogenesis offers an avenue to search for climate-smart plants to sustain crop and pasture productivity in the context of global climate change.

热形态发生
当暴露在温暖、无压力的平均温度下时,一些植物器官会以更快的速度生长和发育,而不会影响它们的最终尺寸。其他植物器官在称为热形态发生的反应中表现出形态或发育的特定变化。选定的编码和非编码 RNA、染色质特征、可变剪接变体和信号蛋白会改变它们的丰度、定位和/或内在活性以介导热形态发生。温度、光照和生物钟线索被整合以影响生长素、油菜素类固醇和赤霉素等激素的水平或信号传导。光受体植物色素 B (phyB) 是一种温度传感器,而 phyB-PHYTOCHROME-INTERACTING FACTOR 4 (PIF4)-生长素模块只是控制温度敏感性的复杂网络中的一个线程。
