DCE — Beta vulgaris subsp. vulgaris

Summary

BvDCE (BVRB_6G131740) on sugar beet chromosome 6 encodes a pyridoxal phosphate-dependent decarboxylase with glutamate decarboxylase and sphinganine-1-phosphate aldolase activities, and binds calmodulin, calcium ions, and pyridoxal phosphate. The gene is associated with glutamate and sphingolipid breakdown, GABA formation, and responses to mechanical stimuli and calcium ion detection. It localises to multiple cellular compartments including the ER, plastid, plasmodesma, mitochondria, cytosol, and nucleus. BvDCE has been linked to shoot growth angle, photosynthetic rate, stomatal complex closure time, root development, leaf senescence, seed growth and development, flowering time, and sensitivity to ethylene and abscisic acid. Associations also include drought tolerance, heat stress tolerance, high light and heat stress tolerance, bacterial pathogen resistance, salt tolerance, water-use efficiency, and nitrogen metabolism. Studies of related genes in other species connect the family to GABA accumulation, hypoxia response, herbivory resistance, and fruit ripening.
