RHD2 — Solanum tuberosum

Summary

StRHD2 (PGSC0003DMG400015543) on potato chromosome 11 encodes a superoxide-generating NAD(P)H oxidase, a member of the respiratory burst oxidase (RBOH) family characterized by NADPH_Ox, FAD-binding, and EF-hand calcium-binding domains. The gene is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense, and H₂O₂ biosynthetic processes. It is linked to root hair elongation, development, and tip growth, as well as lateral root induction, root growth, and phosphorus acquisition. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, water use efficiency, stomatal resistance, leaf rolling response, and responses to aluminum, osmotic stress, aphids, and ethylene. Studies of related RBOH family members in other species link the family to salt, heat, cold, and oxidative stress tolerance, late blight resistance, and photosynthetic induction.
