GAD — Triticum turgidum subsp. durum

Summary

TRITD2BV1G158430 (GAD) on durum wheat chromosome 2B encodes a glutamate decarboxylase with pyridoxal phosphate and calmodulin binding activity, and also exhibits sphinganine-1-phosphate aldolase activity. The gene is associated with the GABA shunt, glutamate and sphingolipid breakdown, carboxylic acid metabolism, mRNA transcription, response to water, seed germination, and homeostasis. Its product localises to the ER membrane, ER, and cytosol. The gene is linked to growth stage and germination rate. Studies of related genes in other species connect the family to grain yield, sugar content, drought tolerance, and salt tolerance.
