Climate change profoundly affects the timing of seasonal activities of organisms, known as phenology. The impact of climate change is not unidirectional; it is also influenced by plant phenology as plants modify atmospheric composition and climatic processes. One important aspect of this interaction is the emission of biogenic volatile organic compounds (BVOCs), which link the Earth's surface, atmosphere, and climate. BVOC emissions exhibit significant diurnal and seasonal variations and are therefore considered essential phenological traits. To understand the dynamic equilibrium arising from the interplay between plant phenology and climate, this review presents recent advances in comprehending the molecular mechanisms underpinning plant phenology and its interaction with climate. We provide an overview of studies investigating molecular phenology, genome-wide gene expression analyses conducted in natural environments, and how these studies revolutionize the concept of phenology, shifting it from observable traits to dynamic molecular responses driven by gene–environment interactions. We explain how this knowledge can be scaled up to encompass plant populations, regions, and even the globe by establishing connections between molecular phenology, changes in plant distribution, species composition, and climate.Expected final online publication date for the Annual Review of Plant Biology, Volume 75 is May 2024.

BVOC 介导的植物分子物候和气候反馈

气候变化深刻影响生物体季节性活动的时间，即物候学。气候变化的影响不是单向的；它还受到植物物候的影响，因为植物改变了大气成分和气候过程。这种相互作用的一个重要方面是生物挥发性有机化合物 (BVOC) 的排放，它将地球表面、大气和气候联系在一起。 BVOC 排放表现出显着的昼夜和季节变化，因此被认为是重要的物候特征。为了理解植物物候与气候之间相互作用产生的动态平衡，本文介绍了理解植物物候及其与气候相互作用的分子机制的最新进展。我们概述了分子物候学、在自然环境中进行的全基因组基因表达分析的研究，以及这些研究如何彻底改变物候学的概念，将其从可观察的性状转变为由基因-环境相互作用驱动的动态分子反应。我们解释了如何通过建立分子物候学、植物分布变化、物种组成和气候之间的联系，将这些知识扩展到植物种群、地区甚至全球。《植物生物学年度评论》的预计最终在线发布日期，第 75 卷为 2024 年 5 月。请参阅 http://www.annualreviews.org/page/journal/pubdates 了解修订后的估计。
