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 ...

video: Professor Miltos Tsiantis from the Max Planck Institute for Plant Breeding Research in Cologne talks about his recent work in CELL showing how genes act to determine leaf shape. view more ...

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 ...

The spiral pattern of leaf formation from the point of growth affects the developing leaf's exposure to the plant hormone auxin; This exposure leads to measurable left-right asymmetry in leaf ...
