DCE — Beta vulgaris subsp. vulgaris

Summary

BvDCE (BVRB_6G131770) 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, carboxylic acid metabolism, 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, abscisic acid and ethylene sensitivity, jasmonic acid content, and phenotypes 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 phosphorus deprivation tolerance, hypoxia response, and thigmomorphogenesis.
