RHD2 — Beta vulgaris subsp. vulgaris

Summary

BvRHD2 (BVRB_2G039470) on sugar beet chromosome 2 encodes a protein with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple protein kinase activities, including transmembrane receptor protein tyrosine kinase and calcium-dependent protein serine/threonine kinase activity. The gene is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense response, and H2O2 biosynthetic process. It is linked to root hair elongation, root hair tip growth, root growth, lateral root induction, and root epidermal cell differentiation. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, water use efficiency, stomatal resistance, leaf rolling response, phototropism, phosphorus uptake, anthocyanin content, and responses to aluminum, magnesium, osmotic stress, ethylene, and brassinosteroids. The protein localizes to the endosome, ER, Golgi, plastid, and vacuole.
