Cell-surface receptors are involved in many biological processes, including immunity and development. It was unclear how these receptors evolve to become specialized in different biological processes. I analyzed more than 200,000 cell-surface receptors from 350 genomes, and traced the origin of immune-specific receptor-like proteins (RLPs) in plants. I discovered that the motifs required for co-receptor interaction in RLPs are related to those of the receptor-like kinase (RLKs), which perceives phytohormones and controls growth and development. These data suggest that the immunity- and development-receptors share a common origin. This work also shows that plants have evolved to perceive different environmental signals to activate the appropriate responses.
