We all appreciate the fantastic diversity of flowers. How flowers diversified, however, remains largely enigmatic. The mechanisms underlying the diversification of flowers are complex because the overall appearance of a flower is determined by many factors, such as the shape and size of its receptacle, and the arrangement, number, type, shape and colour of floral organs. Modifications of the developmental trajectories of a flower and its components, therefore, can lead to the generation of new floral types. In this Review, by summarizing the recent progress in studying the initiation, identity determination, morphogenesis and maturation of floral organs, we present our current understanding of the mechanisms underlying the diversification of flowers.

我们都十分欣赏各种各样奇妙的花。然而，关于花是如何多样化的还不是很清楚。由于决定花整个外观上的表现有许多的因素，比如花托的形状和大小以及花器官的排列、数量、类型、形状和颜色，因此花多样化背后潜在的机制十分的复杂。对于花发育轨迹及其组成成分的修饰可以产生新的类型的花。本文综述了近期有关花器官起始、属性决定、形态发生以及成熟相关的研究进展，并且总结了目前我们对于花多样化背后潜在机制的理解。
