STM — Brassica oleracea

Summary

BoSTM (BOLC102_C03P084570.1) on cabbage chromosome 3 encodes a serine hydroxymethyltransferase (SHMT) with glycine hydroxymethyltransferase and glutamate synthase (ferredoxin) activities, binding pyridoxal phosphate. The gene is associated with glycine, L-serine and tetrahydrofolate metabolism, glycine decarboxylation, floral whorl morphogenesis, meristem maintenance and identity, internode patterning, secondary shoot formation, regeneration, and regulation of salinity response. It has been linked to traits including shoot apical meristem development, phyllotaxy, floral organ identity, leaf curling and chlorosis, peduncle length, flowering time, and salt, oxidative stress, high light, cadmium and biotic stress tolerance. Localisation evidence connects the product to mitochondria, chloroplast stroma and thylakoid, stromules, cytosol and the apoplast. Studies of related genes in other species link the family to photorespiratory metabolism, basal immunity, thermo-resilience and glutamate biosynthesis.
