Auxins (IAA) and cytokinins (CKs) are the most influential phytohormones, having multifaceted roles in plants. They are key regulators of plant growth and developmental processes. Additionally, their interplay exerts tight control on plant development and differentiation. Although several reviews have been published detailing the auxin-cytokinin interplay in controlling root growth and differentiation, their roles in the shoot, particularly in leaf morphogenesis are largely unexplored. Recent reports have provided new insights on the roles of these two hormones and their interplay on leaf growth and development. In this review, we focus on the effect of auxins, CKs, and their interactions in regulating leaf morphogenesis. Additionally, the regulatory effects of the auxins and CKs interplay on the phyllotaxy of plants are discussed.
生长素（IAA）和细胞分裂素（CKs）是最具影响力的植物激素，在植物中具有多方面的作用。它们是植物生长和发育过程的关键调节因子。此外，它们之间的相互作用对植物的发育和分化施加了严格的控制。尽管已经发表了几篇综述，详细阐述了生长素 - 细胞分裂素在控制根生长和分化中的相互作用，但它们在地上部分，特别是在叶片形态发生中的作用在很大程度上尚未得到探索。最近的报告为这两种激素的作用及其在叶片生长和发育中的相互作用提供了新的见解。在本综述中，我们重点关注生长素、细胞分裂素及其相互作用在调节叶片形态发生中的作用。此外，还讨论了生长素和细胞分裂素相互作用对植物叶序的调节作用。
