DCE — Daucus carota subsp. sativus

Summary

DCAR_003413 (DcDCE) on carrot chromosome 1 encodes a glutamate decarboxylase (EC 4.1.1.15) with pyridoxal phosphate-dependent decarboxylase and transferase domains, also exhibiting sphinganine-1-phosphate aldolase activity, calmodulin and calcium ion binding, and protein homodimerization activity. The gene is associated with glutamate and sphingolipid breakdown, GABA formation, and responses to nitrogen starvation, mechanical stimuli, and calcium ion detection. Its product localizes to the ER membrane, plastid, plasmodesma, mitochondria, cytosol, and nucleus. DcDCE is linked to shoot growth angle, ethylene sensitivity, jasmonic acid content, photosynthetic rate, stomatal complex closure time, root development, leaf senescence, seed growth and development, abscisic acid sensitivity, flowering time, salt tolerance, and phenotypes including E-2-hexenal response, bacterial pathogen resistance, heat stress tolerance, high light and heat stress tolerance, water-use efficiency, GABA biosynthesis, nitrogen metabolism, drought tolerance, shoot growth, GABA content, hypoxia-induced alanine accumulation, calcium/calmodulin signaling, root development, GABA production, stomatal closure, calcium channel activity, calmodulin mRNA accumulation in leaves, starch accumulation, floral initiation, ABA response, calcium transport, leaf senescence, touch response, electromagnetic field response, seed germination, and reactive oxygen species production.
