Abstract

The appearance of leaves with flattened laminae about 400 million years (Myr) ago had broad impacts on the Earth's ecosystem. The influential telome theory presents a model for this evolutionary transition, although it lacks plausible molecular evidence. Recently, microtubule-mediated mechanical feedback was proposed as a parsimonious alternative mechanism to explain leaf blade evolution.

Keywords: asymmetry; flattening; leaf; mechanical feedback; telome.
