不同植物物种的地上植物体可以有非常不同的形式或结构，这些形式或结构是由一组有限的构建块（具有腋生分生组织的叶子、茎或枝和花）的反复重新部署而产生的。不同植物科和物种中植物花序的独特结构决定了野生和栽培植物的繁殖成功率和产量。花序结构的主要贡献者是腋生分生组织的活动和发育轨迹，这决定了分枝的程度和形成的花的数量。在不同开花植物的遗传和分子分析中，最近的进展揭示了共同的调控原理和独特的参与者和/或调控相互作用，这是花序结构的基础。调节这些监管机构的活动已经导致该领域的产量增加。对潜在的调控相互作用和原理的进一步了解不仅将揭示它们的重新布线如何导致植物形态的改变，而且还将加强以理想方式优化作物物种植物结构的努力。
The above-ground plant body in different plant species can have very distinct forms or architectures that arise by recurrent redeployment of a finite set of building blocks-leaves with axillary meristems, stems or branches, and flowers. The unique architectures of plant inflorescences in different plant families and species, on which this review focuses, determine the reproductive success and yield of wild and cultivated plants. Major contributors to the inflorescence architecture are the activity and developmental trajectories adopted by axillary meristems, which determine the degree of branching and the number of flowers formed. Recent advances in genetic and molecular analyses in diverse flowering plants have uncovered both common regulatory principles and unique players and/or regulatory interactions that underlie inflorescence architecture. Modulating activity of these regulators has already led to yield increases in the field. Additional insight into the underlying regulatory interactions and principles will not only uncover how their rewiring resulted in altered plant form, but will also enhance efforts at optimizing plant architecture in desirable ways in crop species.
