Phytohormones participate in various processes over the course of a plant’s lifecycle. In addition to the five classical phytohormones (auxins, cytokinins, gibberellins, abscisic acid, and ethylene), phytohormones such as brassinosteroids, jasmonic acid, salicylic acid, strigolactones, and peptides also play important roles in plant growth and stress responses. Given the highly interconnected nature of phytohormones during plant development and stress responses, it is challenging to study the biological function of a single phytohormone in isolation. In the current Review, we describe the combined functions and signaling cascades (especially the shared points and pathways) of various phytohormones in leaf development, in particular, during leaf primordium initiation and the establishment of leaf polarity and leaf morphology as well as leaf development under various stress conditions. We propose a model incorporating the roles of multiple phytohormones in leaf development and stress responses to illustrate the underlying combinatorial signaling pathways. This model provides a reference for breeding stress-resistant crops.

植物激素及其信号传导途径在叶片发育和胁迫响应中的作用

植物激素在植物生命周期中参与各种过程。除了五种经典的植物激素（植物生长素，细胞分裂素，赤霉素，脱落酸和乙烯）外，植物激素如油菜素甾醇，茉莉酸，水杨酸，Strigolactones和肽在植物生长和胁迫响应中也起着重要作用。鉴于植物激素在植物发育和胁迫响应过程中具有高度相互联系的性质，因此孤立地研究单个植物激素的生物学功能具有挑战性。在当前的综述中，我们描述了叶片发育中各种植物激素的组合功能和信号级联反应（尤其是共享点和途径），特别是，在不同的胁迫条件下，叶片原基萌发过程中叶片极性和叶片形态的建立以及叶片的发育。我们提出了一个模型，该模型结合了多种植物激素在叶片发育和胁迫响应中的作用，以说明潜在的组合信号传导途径。该模型为抗逆作物的育种提供了参考。
