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.
当暴露在温暖、非胁迫性的平均温度下时，一些植物器官会以更快的速度生长和发育，而不会影响其最终尺寸。其他植物器官会表现出特定的形态或发育变化，这种反应被称为热形态发生。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改变其丰度、定位和/或内在活性，以介导热形态发生。温度、光照和昼夜节律线索被整合在一起，影响激素（如生长素、油菜素内酯和赤霉素）的水平或信号。光受体光敏色素 B（phyB）是一种温度传感器，phyB-PHYTOCHROME-INTERACTING FACTOR 4（PIF4）-生长素模块只是一个复杂网络中的一个线程，该网络控制着温度敏感性。热形态发生为寻找适应气候变化的智能植物提供了一个途径，以维持作物和牧场在全球气候变化背景下的生产力。
