Plant responses to specific environmental stimuli at the molecular and genetic levels have been widely reported in recent decades, mainly as a consequence of the availability of new laboratory techniques. However, understanding the complex implications of these observations at the ecosystem level remains one of the greatest challenges facing plant science today. Recently, new experimental strat...
