Plants display remarkable developmental flexibility as they continuously sense and respond to changes in their environment. This flexibility allows them to select the optimal timing for critical developmental decisions such as when to flower. Ambient temperature is a major environmental factor that influences flowering; the mechanisms involved in ambient temperature-responsive flowering have attracted particular attention as a consequence of the effects of global climate change on temperature. PHYTOCHROME INTERACTING FACTOR 4 and alternative splicing of FLOWERING LOCUS M affect temperature-responsive flowering; however, the exact temperature-sensing mechanism in plants remains elusive. Further study of these molecular mechanisms will contribute to our understanding of how plants sense ambient temperature and respond via diverse biological signaling cascades.
植物表现出显著的发育灵活性，因为它们不断感知并响应环境变化。这种灵活性使它们能够为关键的发育决策选择最佳时机，比如何时开花。环境温度是影响开花的一个主要环境因素；由于全球气候变化对温度的影响，参与环境温度响应开花的机制受到了特别关注。光敏色素相互作用因子4和开花位点M的可变剪接影响温度响应开花；然而，植物中确切的温度感知机制仍然难以捉摸。对这些分子机制的进一步研究将有助于我们理解植物如何感知环境温度并通过多种生物信号级联反应做出响应。
