RPM1 — Glycine max

Summary

GLYMA_01G010700V4 (GmRPM1, also known as GmRPS3) on soybean chromosome 1 encodes a protein with domains characteristic of plant disease resistance proteins, including NB-ARC, Rx_N, and LRR repeats. The protein exhibits transmembrane receptor serine/threonine kinase activity, ubiquitin-protein transferase activity, and binds ATP, ADP, and metal ions. GmRPM1 is associated with detection of bacteria, activation of defense responses, positive and negative regulation of the hypersensitive response, PTI signaling, and defense response by callose deposition. It is linked to bacterial blight disease resistance, drought tolerance, salt tolerance, leaf rolling, variegated leaf, stomatal closure, chloroplast development, and plant growth traits. The protein localizes to the plasma membrane, endosome, chloroplast envelope, and mitochondria. Studies of related genes in other species link the family to broad-spectrum disease resistance, flagellin perception, and innate immune responses.
