RHD2 — Solanum tuberosum

Summary

StRHD2 (PGSC0003DMG400025701) on potato chromosome 5 encodes a respiratory burst oxidase, a protein with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities including transmembrane receptor protein tyrosine kinase and calcium-dependent protein serine/threonine kinase activity. It is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense response, H2O2 biosynthetic process, and detection of bacteria. The gene is linked to root hair elongation, root growth, lateral root induction, auxin distribution, and root hair tip growth. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, water use efficiency, stomatal resistance, leaf rolling response, phototropism, aluminum response, phosphorus uptake, and anthocyanin content. Studies of related genes in other species link the family to salt, cold, heat, and oxidative stress tolerance, late blight resistance, and lateral root development.
