植物能够感知温度升高几度，并适当地适应其代谢和生长过程。为此，植物产生各种信号分子，在整个植物体内发挥作用。在此，我们报道根源性 GA(12)（生物活性赤霉素的前体）介导拟南芥中的热响应芽生长。我们的数据表明，GA(12) 从根到芽的易位使得生长能够对环境温度变化做出灵活的响应。
Plants are able to sense a rise in temperature of several degrees, and appropriately adapt their metabolic and growth processes. To this end, plants produce various signalling molecules that act throughout the plant body. Here, we report that root-derived GA(12), a precursor of the bioactive gibberellins, mediates thermo-responsive shoot growth in Arabidopsis. Our data suggest that root-to-shoot translocation of GA(12) enables a flexible growth response to ambient temperature changes.
