Elucidation of gene regulatory networks (GRNs) underlying aspects of leaf development in multiple model species has uncovered surprisingly plastic regulatory architecture. The meticulously mapped network interactions in one model species cannot now be assumed to map directly onto a different species. Despite these overall differences, however, many modules do appear to be almost universal. Extrapolating findings across different model systems will demand great care but promises to reveal a rich tapestry of themes in GRN architecture and regulation. The purpose of this review is to approach the field of leaf development from the perspectives of the evolution of developmental systems that orchestrate leaf development.
阐明多个模式物种中叶片发育相关的基因调控网络（GRNs）揭示了惊人的可塑性调控结构。在一个模式物种中精心绘制的网络相互作用现在不能直接假定映射到另一个物种上。然而，尽管存在这些总体差异，许多模块似乎几乎是普遍存在的。在不同的模型系统中推断发现需要非常谨慎，但有望揭示 GRN 结构和调控的丰富主题。本文综述的目的是从协调叶片发育的发育系统的进化角度来探讨叶片发育领域。
