DCE — Beta vulgaris subsp. vulgaris

Summary

BvDCE (BVRB_6G131780) on sugar beet chromosome 6 encodes a pyridoxal phosphate-dependent decarboxylase with glutamate decarboxylase and sphinganine-1-phosphate aldolase activities, and binds calmodulin and calcium ions. The gene is associated with glutamate and sphingolipid breakdown, cellular response to nitrogen starvation, calcium ion detection, and mechanical stimulus response. Its product localises to the ER membrane, plastid, plasmodesma, mitochondria, cytosol and nucleus. BvDCE is associated with shoot growth angle, photosynthetic rate, stomatal complex closure time, root development, leaf senescence, seed growth and development, flowering time, ethylene and abscisic acid sensitivity, jasmonic acid content, and traits including drought tolerance, heat stress tolerance, bacterial pathogen resistance, water-use efficiency, salt tolerance, and GABA content. Studies of related genes in other species connect the family to hypoxia response, fruit ripening, herbivory resistance, and phosphorus deprivation tolerance.
