The coordination of the timing of flowering with seasonal and development cues is a critical life-history trait that has been shaped by evolution to maximize reproductive success. Decades of studying many plant species have revealed several of the fascinating systems that plants have evolved to control flowering time: such as the perception of day length in leaves, which leads to the production of a mobile signal, florigen, that promotes flowering at the shoot apical meristem; the vernalization process in which exposure to prolonged cold results in meristem competence to flower; and the juvenile to adult phase transition. Arabidopsis research has contributed greatly to understanding these systems at a molecular level.
开花时间与季节和发育线索的协调是一个关键的生活史特征，它是通过进化来最大限度地提高繁殖成功率的。几十年来，对许多植物物种的研究揭示了植物进化出的几种控制开花时间的迷人系统：例如，叶片对日照长度的感知，导致产生一种可移动的信号，成花素，促进茎尖分生组织开花；春化过程，即长时间低温暴露导致分生组织有开花能力；以及幼年期到成年期的转变。拟南芥的研究极大地促进了我们在分子水平上对这些系统的理解。
