DCE — Beta vulgaris subsp. vulgaris

Summary

BvDCE (BVRB_9G214920) on sugar beet chromosome 9 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, the TCA cycle, sucrose metabolism, and responses to salt and mechanical stimuli. Its product localises to the ER, plastid, plasmodesma, mitochondria, cytosol, and nucleus. BvDCE is associated with shoot growth angle, photosynthetic rate, stomatal closure, leaf senescence, root development, flowering time, and sensitivity to ethylene, abscisic acid, and jasmonic acid. It is linked to drought and salt tolerance, heat stress tolerance, water-use efficiency, bacterial pathogen resistance, and GABA biosynthesis. Related genes in other species are linked to hypoxia response, thigmomorphogenesis, and herbivory resistance.
