RHD2 — Beta vulgaris subsp. vulgaris

Summary

BvRHD2 (BVRB_5G123540) on sugar beet chromosome Bvchr5_un.sca003 encodes a protein with NADPH oxidase, cytochrome b245 heavy chain, FAD-binding, ferric reductase, and EF-hand domains. It is annotated 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. BvRHD2 is associated with immune response-regulating signaling pathways, respiratory burst involved in defense response, defense response by callose deposition, H2O2 biosynthetic process, and detection of bacteria. It is linked to root hair elongation, root hair development and tip growth, lateral root induction, root growth, cell wall strength, phosphorus acquisition, and auxin distribution. The gene is also associated with grain yield, seed yield, biomass yield, bacterial blight disease resistance, water use efficiency, stomatal resistance, anthocyanin content, and responses to osmotic stress, aluminum, aphids, and brassinosteroids.
