STM — Brassica oleracea

Summary

BoSTM (BOLC102_C01P001010.1_BOLC102_V1) on cabbage chromosome 1 encodes a serine hydroxymethyltransferase (SHMT) with glycine hydroxymethyltransferase and pyridoxal phosphate binding activities, and also carries domains associated with pyridoxal phosphate-dependent transferases. The gene is linked to glycine, serine and tetrahydrofolate metabolism, photorespiration, and the glycine cleavage system. It is associated with meristem development and identity, floral organ morphogenesis, inflorescence and shoot development, and pattern specification. Associations extend to salt, oxidative, high light and abiotic stress tolerance, as well as leaf chlorosis, leaf curling, flowering time, phyllotaxy, abscisic acid sensitivity, and plant growth and development traits. The encoded protein localises to mitochondria, chloroplast stroma and thylakoid, cytosol, and apoplast. Studies of related genes in other species connect the family to photorespiratory metabolism, nitrogen assimilation, and iron homeostasis.
