Abstract/OtherAbstract:
The colonization of land by multicellular green plants was a fundamental step in the evolution of life on earth. Land plants evolved from fresh-water aquatic algae, and the transition to a terrestrial environment required the acquisition of developmental plasticity appropriate to water availability conditions ranging from drought to flood. Here we show that extant bryophytes exhibit submergence-induced developmental plasticity, suggesting that submergence responses evolved relatively early in land plant evolution. We also show that a major component of the bryophyte submergence response is controlled by the phytohormone ethylene, using a perception mechanism that has subsequently been conserved throughout land plant evolution. Thus a plant environmental response mechanism, with major ecological and agricultural importance, likely had its origins in the very earliest stages of land colonization. © 2012 The Authors.
