GAD (TRAESCS4B02G231400) — triticum aestivum

Summary

TRAESCS4B02G231400 (GAD) on wheat chromosome 4B encodes a protein with pyridoxal phosphate-dependent decarboxylase and transferase domains, and is associated with glutamate decarboxylase activity, sphinganine-1-phosphate aldolase activity, calmodulin binding, calcium ion binding, and pyridoxal phosphate binding. The gene is associated with the GABA shunt, glutamate breakdown, sphingolipid breakdown, calcium ion detection, response to nitrate, response to karrikin, mechanical stimulus response, and response to abiotic stimulus. It is linked to traits including shoot growth angle, leaf chlorophyll content, osmotic response sensitivity, jasmonic acid content, stomatal complex closure time, root development, leaf senescence, seed growth and development, abscisic acid sensitivity, flowering time, and salt tolerance. Localization evidence connects the product to the ER membrane, ER, plasmodesmata, plastid, mitochondria, cytosol, and nucleus. Studies of related genes in other species link the family to hypoxia response, flooding tolerance, herbivory resistance, and thigmomorphogenesis.
