STM — Brassica napus

Summary

BnSTM (DARMORV10_C01P01260.1) on chromosome C01 of oilseed rape (Brassica napus) encodes a serine hydroxymethyltransferase (SHMT) family protein with pyridoxal phosphate binding and glycine hydroxymethyltransferase activity, as well as glutamate synthase (ferredoxin) activity and DNA-binding transcription factor activity. The gene is associated with glycine and L-serine metabolism, tetrahydrofolate interconversion, methylglyoxal anabolism, and photorespiratory metabolism. It has been linked to shoot apical meristem development, inflorescence meristem identity, floral whorl morphogenesis, and plant organ formation. Associations with agronomic traits include drought tolerance, salt tolerance, flowering time, leaf chlorosis, peduncle length, and fruit development. The gene is also connected to oxidative stress response, abscisic acid sensitivity, and sodium uptake. Related genes in other species link the family to photorespiration, basal immunity, and stem growth.
