RHD2 — Beta vulgaris subsp. vulgaris

Summary

BvRHD2 (BVRB_8G190890) on sugar beet chromosome 8 encodes a protein with NADPH oxidase, FAD-binding, ferric reductase, and EF-hand calcium-binding domains, and is annotated with NAD(P)H oxidase H2O2-forming activity, calcium ion binding, and multiple kinase activities. The gene is associated with immune response-regulating signaling, defense response by callose deposition, respiratory burst involved in defense response, H2O2 biosynthetic process, root epidermal cell differentiation, and carbohydrate homeostasis. It is linked to grain yield, seed yield, biomass yield, bacterial blight disease resistance, root hair length and elongation, leaf rolling, water use efficiency, stomatal resistance, anthocyanin content, aluminum and osmotic stress responses, and phototropism. Related genes in other species are associated with salt, cold, and heat stress tolerance, lateral root development, and reactive oxygen species homeostasis.
