RHD2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_8G200920 (RHD2) in sugar beet encodes a transmembrane 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. The gene is associated with defense responses, including respiratory burst involved in defense response, callose deposition, and immune response-regulating signaling pathways, as well as H2O2 biosynthetic process, root epidermal cell differentiation, and carbohydrate homeostasis. It is linked to grain yield, seed yield, biomass yield, water use efficiency, bacterial blight disease resistance, aphid response, root hair length, leaf rolling response, and phototropism. The gene is also connected to root hair elongation, lateral root induction, root growth, and phosphorus acquisition. Related genes in other species are linked to salt, cold, heat, and oxidative stress tolerance, as well as lateral root development and photosynthetic induction.
