Leaves of green plants vary widely in morphology. However, the underlying cell types and structures observed in leaves of different species are remarkably similar. Although we can adequately describe leaf development in morphological terms we cannot yet explain interactions at the cellular level. In recent years molecular genetics has been used extensively to address a variety of developmental questions. The isolation of a wide variety of mutants disrupted in numerous aspects of leaf ontogeny has led to the cloning of genes involved in various developmental processes. In this review we consider advances that have been made in understanding shoot apical meristem organization, leaf initiation and the development of leaf form. In particular we concentrate on progress, that has been made in understanding cellular differentiation in the epidermis, and within the interior of the leaf, namely the photosynthetic cells and the vasculature.

绿色植物的叶片在形态上差异很大。然而，在不同物种的叶片中观察到的潜在细胞类型和结构却非常相似。尽管我们可以用形态学术语充分描述叶片发育，但我们仍无法解释细胞水平上的相互作用。近年来，分子遗传学已被广泛用于解决各种发育问题。分离出在叶片个体发育的许多方面受到破坏的各种突变体，导致了参与各种发育过程的基因的克隆。在这篇综述中，我们考虑了在理解茎尖分生组织组织、叶片起始和叶片形态发育方面取得的进展。特别是，我们专注于在理解表皮以及叶片内部（即光合细胞和维管系统）的细胞分化方面取得的进展。目录摘要533 一、引言533 二、茎的生长533 三、叶片起始534 四、叶片形态发育536 五、细胞分化537 六、展望548 七、致谢549 八、参考文献549
