植物器官的大小对环境条件有高度的反应。植物的胚胎茎，或下胚轴，表现出表型可塑性，对光和温度的反应。避阴物种的下胚轴会伸长，以超越邻近植物并确保获得阳光。在高温下也发生类似的伸长。然而，人们对环境光和温度如何相互作用影响植物生长知之甚少。我们发现，遮荫结合温暖的温度产生了协同下胚轴生长反应，依赖于植物色素相互作用因子7（PIF 7）和生长素。这种独特但与农业相关的情景几乎完全独立于PIF 4活性。我们表明，温暖的温度是足以促进PIF 7 DNA结合，但不是转录激活，我们证明，额外的，未知的因素/s必须工作下游的phyB-PIF-生长素模块。我们的研究结果将改善植物在高密度生长时如何应对环境温度升高的预测。植物下胚轴伸长对光和温度的响应。在这里，作者表明，遮荫结合温暖的温度协同增强下胚轴的生长反应，通过PIF 7转录因子，生长素，和尚未未知的因素。
The size of plant organs is highly responsive to environmental conditions. The plant’s embryonic stem, or hypocotyl, displays phenotypic plasticity, in response to light and temperature. The hypocotyl of shade avoiding species elongates to outcompete neighboring plants and secure access to sunlight. Similar elongation occurs in high temperature. However, it is poorly understood how environmental light and temperature cues interact to effect plant growth. We found that shade combined with warm temperature produces a synergistic hypocotyl growth response that dependent on PHYTOCHROME-INTERACTING FACTOR 7 (PIF7) and auxin. This unique but agriculturally relevant scenario was almost totally independent on PIF4 activity. We show that warm temperature is sufficient to promote PIF7 DNA binding but not transcriptional activation and we demonstrate that additional, unknown factor/s must be working downstream of the phyB-PIF-auxin module. Our findings will improve the predictions of how plants will respond to increased ambient temperatures when grown at high density. Plant hypocotyl elongation response to light and temperature. Here the authors show that shade combined with warm temperature synergistically enhances the hypocotyl growth response via the PIF7 transcription factor, auxin, and as yet unknown factor.
