Abstract:
Plant receptor-like proteins (RLPs) are a family of transmembrane receptors which are distinguished from receptor-like kinases (RLKs) by their lack of a cytoplasmic kinase domain. RLPs continue to be implicated in a broad range of plant immunological and developmental processes as critical sensors or participants in receptor complexes on the plasma membrane. RLPs often associate with RLKs to activate or attenuate signal perception and relay. Some RLPs also physically cluster with RLKs and bear similar expression patterns. Here, we discuss the characteristics, function, and expression of characterized RLPs in the context of their associated RLKs in plant immunity and development.
