RS2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_006460 (RS2) in sugar beet encodes a protein belonging to the glycosyl hydrolase 36 family, with annotated raffinose synthase activity, galactinol-raffinose galactosyltransferase activity, and DNA-binding transcription factor activity. The gene is associated with raffinose breakdown and anabolism, stachyose anabolism, and oligosaccharide anabolism. RS2 is linked to salinity tolerance in sugar beet. It is also associated with leaf formation, polarity specification of the adaxial/abaxial axis, asymmetric cell division, regulation of innate immune response, and defence responses to bacteria, fungi, and viruses. Associations include raffinose content, flowering time, leaf and flower morphology, shoot and fruit development, and light intensity response. The protein localises to the nucleus, cytoplasm, nucleolus, plasmodesma, and condensed chromosome. Related genes in other species link the family to leaf polarity, meristem development, and fruit patterning.
