Plant leaves develop in accordance with a common basic program, which is flexibly adjusted to the species, developmental stage and environment. Two key stages of leaf development are morphogenesis and differentiation. In the case of compound leaves, the morphogenesis stage is prolonged as compared to simple leaves, allowing for the initiation of leaflets. Here, we review recent advances in the understanding of how plant hormones and transcriptional regulators modulate compound leaf development, yielding a substantial diversity of leaf forms, focusing on four model compound leaf organisms: cardamine (Cardamine hirsuta), tomato (Solanum lycopersicum), medicago (Medicago truncatula) and pea (Pisum sativum).
植物叶片的发育遵循一个普遍的基本程序，该程序可灵活地适应物种、发育阶段和环境。叶片发育有两个关键阶段，即形态发生和分化。在复叶的情况下，与简单叶相比，形态发生阶段延长，从而允许小叶的起始。在这里，我们回顾了近年来关于植物激素和转录因子如何调节复叶发育的理解进展，产生了大量不同形式的叶片，重点介绍了四种模式复叶生物：碎米荠（Cardamine hirsuta）、番茄（Solanum lycopersicum）、紫花苜蓿（Medicago truncatula）和豌豆（Pisum sativum）。
