As an organism grows, patterns of gene expression emerge which are instrumental in shaping a variety of organs and structures. Interactions between gene expression and morphology are complex and little understood. Part of the problem lies in a lack of methods for assessing tissue growth and patterning quantitatively. Leaves provide a particularly interesting system for investigating the relationships between growth and patterning, as vein pattern formation and leaf growth are closely coupled, and the plant hormone auxin plays a major role in both processes.

随着生物体的生长，基因表达模式的出现有助于塑造各种器官和结构。基因表达和形态之间的相互作用是复杂的，而且鲜为人知。部分问题在于缺乏评估组织生长和图案化的方法。叶片为研究生长和模式之间的关系提供了一个特别有趣的系统，因为叶脉模式的形成和叶片的生长是紧密耦合的，而植物激素生长素在这两个过程中都发挥着重要作用。
