Leaves come in a wide variety of shapes, from simple to lobed to dissected. A new study suggests this variation is determined by a preferred evolutionary genetic pathway that modifies shape by regulating regional growth in the developing leaf.
叶片有多种形状，从简单的到有裂片的到分裂的。一项新的研究表明，这种变异是由一种优选的进化遗传途径决定的，该途径通过调节发育中叶的区域生长来改变形状。
