RPS2 — Arabidopsis thaliana

Summary

AT4G26090 (RPS2) in Arabidopsis thaliana encodes a disease resistance protein of the NBS-LRR family, containing an AAA+ ATPase domain and NB-ARC motifs. The gene is associated with resistance to Pseudomonas syringae, bacterial pathogen immunity, and phytoplasma resistance. It is also linked to biological processes including carbon dioxide transport, membrane depolarization, glucosinolate breakdown, cadmium detoxification, and regulation of proton transport. The protein localizes to the plasma membrane, vacuolar membrane, and stress granules. RPS2 is associated with traits such as shoot cadmium content, phototropism, carbon isotope discrimination, leaf rolling, vivipary, biomass yield, and responses to bacterial blight, viruses, and insects. Studies of related genes in other species link the family to drought tolerance, photosynthetic efficiency, and cadmium tolerance.
