DCE — Cucumis melo

Summary

MELO3C001938.2 (CmDCE) on melon chromosome 13 encodes a pyridoxal-phosphate-dependent decarboxylase with glutamate decarboxylase and sphinganine-1-phosphate aldolase activities, and binds calmodulin and calcium. The gene is associated with the GABA shunt, glutamate and sphingolipid breakdown, polyamine anabolism, and responses to nitrogen starvation, mechanical stimuli, and nitric oxide storage. Its product localises to the ER membrane, plastid, plasmodesma, mitochondria, cytosol and nucleus. CmDCE is linked to shoot growth angle, net photosynthetic rate, ethylene and abscisic acid sensitivity, stomatal closure, leaf senescence, root development, seed growth, flowering time, and salt tolerance. It has also been connected to bacterial pathogen resistance, heat and drought tolerance, water-use efficiency, and hypoxia-induced alanine accumulation. Studies of related genes in other species link the family to fruit ripening, herbivory resistance, and thigmomorphogenesis.
