The Mechanical Feedback Theory of Leaf Lamina Formation
Résumé
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.
