RHD2 — Arabidopsis thaliana

Summary

AT5G51060 (RHD2, also known as RBOHC) encodes a respiratory burst oxidase homolog protein in Arabidopsis thaliana chromosome 5, with NAD(P)H oxidase H2O2-forming activity and calcium ion binding. The gene is associated with reactive oxygen species homeostasis and regulation, cell division, and potassium deficiency response. RHD2 has been linked to numerous agronomically relevant traits including root hair density and length, root weight, grain yield, seed yield, biomass yield, bacterial blight disease resistance, aluminum response, phosphorus content and uptake, osmotic response sensitivity, and leaf growth and development. The encoded protein localizes to multiple cellular compartments including the endosome, Golgi complex, plastid, and extracellular space. Studies of related genes in other species link the family to stress tolerance, lateral root development, and tuber dormancy release.
