RHD2 — Solanum tuberosum

Summary

StRHD2 (PGSC0003DMG400030390) on potato chromosome 6 encodes a protein with NADPH_Ox, Cyt_b245_heavy_chain, FAD-bd_8, and EF-hand domains, and is annotated with superoxide-generating NAD(P)H oxidase activity, calcium ion binding, and multiple kinase-related molecular functions. It is associated with immune response-regulating signaling, respiratory burst involved in defense response, defense response by callose deposition, and H2O2 biosynthetic process. The gene is linked to root hair elongation, root hair formation and tip growth, lateral root induction, root growth, auxin distribution, and cell wall strength. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, aphid response, water use efficiency, stomatal resistance, leaf rolling, phototropism, phosphorus uptake, aluminum response, osmotic sensitivity, brassinosteroid sensitivity, ethylene sensitivity, anthocyanin content, and cadmium tolerance. Studies of related genes in other species link the family to salt, cold, heat, and oxidative stress tolerance, late blight resistance, and reactive oxygen species homeostasis.
