Leaves are a significant component of the shoot system in grasses, functioning in light capture and photosynthesis. Leaf width, length, and angle are expressions of development that collectively define canopy architecture. Thus, the distinctive morphology of grass leaves is an interdependent readout of developmental patterning and growth along the proximal-distal, medial-lateral, and adaxial-abaxial axes. Here, we review the chronology of patterning and growth, namely along the proximal-distal axis, during maize leaf development. We underscore that patterning and growth occur simultaneously, making use of shared developmental gradients and molecular pathways.

玉米叶片发育的动态：在生长模式的同时生长

叶子是禾本科植物枝条系统的重要组成部分，在光捕获和光合作用中起作用。叶子的宽度、长度和角度是共同定义树冠结构的发展表达。因此，草叶的独特形态是沿近端-远端、内侧-外侧和近轴-远轴轴的发育模式和生长的相互依赖的读数。在这里，我们回顾了玉米叶片发育过程中图案形成和生长的年表，即沿近-远轴。我们强调模式化和生长同时发生，利用共享的发育梯度和分子途径。
