叶是植物进行光合作用和蒸腾作用的主要场所, 对植物的生长发育具有重要的作用。叶的发育包括叶原基的形成和极性的建立, 大量研究表明, 叶发育建成受到众多转录因子、小分子RNA以及生长素等因子的调控。文章综述了近年来叶发育和形态建成的分子机制研究进展, 以期了解叶发育的调控网络。

Leaf plays important roles during plant development for their function of photosynthesis and transpiration. Leaf development includes initiation of leaf primordium and establishment of leaf polarity. Various studies indicate that leaf de-velopment is controlled through the interaction of transcription factors, small RNAs and auxin. This review focuses on re-cent advances in studying on leaf development and morphogenesis, and provides information on the regulation network in the process.
