尽管萼片、花瓣、雄蕊和心皮的形态不同，但所有这些花器官都被认为是类似于叶的基态器官的修改版本。基态发育程序的修改是由花器官身份基因编码的MADS结构域转录因子的不同组合精心策划的。近年来，花器官特性基因控制的基因调控网络和控制叶片发育的遗传途径已被揭示。本文以模式植物拟南芥（Arabidopsis thaliana）为例，探讨了花器官的特性与茎器官形态建成和分化的关系。花器官识别基因与近轴-远轴模式、器官边界形成、组织生长和细胞分化相关基因之间存在直接联系。与此同时，预测模型已被开发出来，以解释调控基因的活性如何通过细胞间信号传导进行协调，并受到组织力学的约束。当结合起来，这些进步提供了一个独特的机会，揭示了叶状器官在进化过程中是如何“蜕变”成花器官的，并显示了植物形态生成的关键调控点。
In spite of the different morphologies of sepals, petals, stamens, and carpels, all these floral organs are believed to be modified versions of a ground-state organ similar to the leaf. Modifications of the ground-state developmental programme are orchestrated by different combinations of MADS-domain transcription factors encoded by floral organ identity genes. In recent years, much has been revealed about the gene regulatory networks controlled by the floral organ identity genes and about the genetic pathways that control leaf development. This review examines how floral organ identity is connected with the control of morphogenesis and differentiation of shoot organs, focusing on the model speciesArabidopsis thaliana. Direct links have emerged between floral organ identity genes and genes involved in abaxial-adaxial patterning, organ boundary formation, tissue growth, and cell differentiation. In parallel, predictive models have been developed to explain how the activity of regulatory genes can be coordinated by intercellular signalling and constrained by tissue mechanics. When combined, these advances provide a unique opportunity for revealing exactly how leaf-like organs have been ‘metamorphosed’ into floral organs during evolution and showing crucial regulatory points in the generation of plant form.
