湖菜，Rorippa aquatica（芸苔科），是一种半水生植物，根据环境的不同，呈现出各种各样的叶子形状，从单叶到高度分枝的复叶。在同一株植物中，叶子的形状可以变化，这表明这种变化可以用一个简单的模型来解释。为了模拟拟南芥（R. aquatica）复叶的分支结构，在拟南芥（Arabidopsis thaliana）叶片锯齿状分布的理论框架上实现了反应-扩散（RD）模式，并对一维反应-扩散域进行了修改，使其随着RD模式的空间周期性而变形。这种使用迭代模式的简单方法可以创建规则的和嵌套的分支模式。随后，我们通过将理论模型与实验观察到的分支模式进行比较，验证了理论模型的合理性。结果表明，该模型成功地从定性和定量两个方面预测了水杨叶片生长的分枝时间和位置。
Lake cress, Rorippa aquatica (Brassicaceae), is a semi-aquatic plant that exhibits a variety of leaf shapes, from simple leaves to highly branched compound leaves, depending on the environment. Leaf shape can vary within a single plant, suggesting that the variation can be explained by a simple model. In order to simulate the branched structure in the compound leaves of R. aquatica, we implemented reaction-diffusion (RD) patterning onto a theoretical framework that had been developed for serration distribution in the leaves of Arabidopsis thaliana, with the modification of the one-dimensional reaction-diffusion domain being deformed with the spatial periodicity of the RD pattern while expanding. This simple method using an iterative pattern could create regular and nested branching patterns. Subsequently, we verified the plausibility of our theoretical model by comparing it with the experimentally observed branching patterns. The results suggested that our model successfully predicted both the qualitative and quantitative aspects of the timing and positioning of branching in growing R. aquatica leaves.
