SAMS2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_5G122610, designated SAMS2, encodes a protein with methionine adenosyltransferase activity and S-adenosyl-L-methionine synthetase domains. The gene is associated with SAM biosynthetic process, polyamine metabolism, and one-carbon metabolism, and its product localizes to the cytosol and cytoplasm. SAMS2 is linked to pathways including ethylene biosynthesis, mugineic acid biosynthesis, the methionine salvage pathway, and responses to iron deficiency and inorganic nutrient metabolism. It has been connected to salt tolerance (SALTTL trait). Studies of related genes in other species support the family’s association with methionine adenosyltransferase activity (EC 2.5.1.6). In sugar beet, SAMS2 is positioned on chromosome 5 and is associated with hormone signaling and stress-related processes.
