STM — Brassica napus

Summary

BnSTM (DARMORV10_A01P01120.1) encodes a protein with serine hydroxymethyltransferase and pyridoxal phosphate binding domains, and is annotated with glycine hydroxymethyltransferase activity and glutamate synthase (ferredoxin) activity. In oilseed rape, the gene is associated with glycine, serine, tetrahydrofolate, and methylglyoxal metabolism, as well as floral whorl morphogenesis, inflorescence meristem identity, internode patterning, and shoot apical meristem development. It is associated with traits including drought tolerance, salt tolerance, flowering time, leaf chlorosis, peduncle length, and phyllotaxy. The gene is linked to photorespiratory metabolism, oxidative stress tolerance, stomatal closure, and primary root growth. Localisation evidence places the product in mitochondria, chloroplast stroma and thylakoid, and the apoplast. Related genes in other species link the family to basal immunity, thermo-resilience, and stem growth.
