A review article has been published in The Plant Cell. The review outlines the examples of diversification mechanisms in leaf morphology that have been identified so far and discusses whether there are common mechanisms among them and the exceptions. The review was written by Dr. Hokuto Nakayama and Professor Neelima Sinha (University of California, Davis).
