有证据表明，人为介导的全球变暖导致许多植物种群的开花加速。然而，一些植物开花较晚或不受变暖影响的事实，强调了相变、温度和系统发育之间的复杂关系。在这篇综述中，我们介绍了植物如何感知温度变化的新情况，然后讨论了古代开花途径基因在环境、低温和高温调节生殖发育进化中的独立募集。除了揭示更好地理解过去的热气候如何影响植物相变的全球可塑性模式所需的研究领域外，我们还考虑了气候变化对这些物候热响应的影响。
Evidence suggests that anthropogenically-mediated global warming results in accelerated flowering for many plant populations. However, the fact that some plants are late flowering or unaffected by warming, underscores the complex relationship between phase change, temperature, and phylogeny. In this review, we present an emerging picture of how plants sense temperature changes, and then discuss the independent recruitment of ancient flowering pathway genes for the evolution of ambient, low, and high temperature-regulated reproductive development. As well as revealing areas of research required for a better understanding of how past thermal climates have shaped global patterns of plasticity in plant phase change, we consider the implications for these phenological thermal responses in light of climate change.
