在植物中，树叶的形状表现出深刻的多样性。当一片叶子展开时，它的形状是不断变化的。植物也可能在连续的节位产生不同形状的叶子。此外，由于进化过程和环境的影响，树叶的形状在个体、种群和物种之间有所不同。因为树叶的形状可以以许多不同的方式变化，从理论上讲，不同的发育和进化过程的影响是可以分开的，即使在一片树叶的形状内也是如此。在这里，我们测量了来自驯化葡萄(Vitis spp.)的野生近缘葡萄(Vitis spp.)以确定可归因于遗传和发育的叶片形状是否可以彼此分开。我们分离出嵌入在树叶整体形状中的潜在形状(相互独立变化的多变量特征)。这些潜在的形状可以独立于物种身份预测发育阶段，反之亦然。然后，用预测发育的形状对1200个驯化葡萄品种的叶片进行了分期，揭示了叶片形状多样性的时间变化。我们的结果表明，不同的潜在形状结合在一起，在叶片中产生了复合的形态，并且对形状的发育和进化贡献彼此独立。
Across plants, leaves exhibit profound diversity in shape. As a single leaf expands, its shape is in constant flux. Plants may also produce leaves with different shapes at successive nodes. In addition, leaf shape varies among individuals, populations and species as a result of evolutionary processes and environmental influences. Because leaf shape can vary in many different ways, theoretically, the effects of distinct developmental and evolutionary processes are separable, even within the shape of a single leaf. Here, we measured the shapes of > 3200 leaves representing > 270 vines from wild relatives of domesticated grape (Vitis spp.) to determine whether leaf shapes attributable to genetics and development are separable from each other. We isolated latent shapes (multivariate signatures that vary independently from each other) embedded within the overall shape of leaves. These latent shapes can predict developmental stages independent from species identity and vice versa. Shapes predictive of development were then used to stage leaves from 1200 varieties of domesticated grape (Vitis vinifera), revealing that changes in timing underlie leaf shape diversity. Our results indicate that distinct latent shapes combine to produce a composite morphology in leaves, and that developmental and evolutionary contributions to shape vary independently from each other.
