Leaf size and venation show remarkable diversity across dicotyledons, and are key determinants of plant adaptation in ecosystems past and present. Here we present global scaling relationships of ...

UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict ...

Overexpression of SHR enhance mesophyll cell division, resulting in a substantial reduction in leaf vein density. However, exogenous auxin treatments led to an increase in leaf vein density. Notably, ...
