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.
有证据表明,人为引起的全球变暖加速了许多植物种群的开花。然而,一些植物开花较晚或不受变暖影响这一事实,凸显了物候变化、温度和系统发育之间复杂的关系。在这篇综述中,我们呈现了一个关于植物如何感知温度变化的新观点,然后讨论了古老的开花途径基因如何被独立招募,以进化出对环境、低温和高温调节的生殖发育。除了揭示为了更好地理解过去的热气候如何塑造植物物候变化的全球可塑性模式,我们还考虑了这些物候对气候变化的影响。
