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 ...

Research by Assistant Professor Jacob S. Suissa at the University of Tennessee, Knoxville, is revealing complexity in how ferns have evolved. Instead of the vascular structure inside fern stems ...

Most leaves are green due to the pigment chlorophyll, but other colours, such as oranges, reds and blues, may also be present due to less efficient photosynthetic pigments like anthocyanins, carotenes ...

This flower-like image shows a plant that is not developing quite right. It comes from a study in which scientists at EMBL and the University of Sydney unearthed the molecular feedback loop that ...

Scientists have determined how key developmental genes influence growth of cells to produce such differences in leaf form. The researchers were able to make thale cress, which typically produces ...

A comprehensive analysis of global patterns in leaf size offers an answer to one of the longest-standing questions in plant ecology - why plant leaf size increases at lower latitudes -- scientists now ...

Watery adaptation: The structure and shape of lotus leaves growing on water (left) and above it (right) is influenced by mechanical forces. (Courtesy: F Xu/Fudan University) When the leaves of the ...
