DCE — Solanum lycopersicum

Summary

SOLYC01G005000.3 (DCE/GAD) encodes a glutamate decarboxylase with pyridoxal phosphate-dependent decarboxylase and transferase domains, also exhibiting sphinganine-1-phosphate aldolase activity and binding calmodulin, calcium ions, and pyridoxal phosphate. In tomato, this gene is associated with GABA accumulation and synthesis, bacterial wilt resistance, and is linked to the GABA shunt, glutamate breakdown, and sphingolipid breakdown. It is associated with fruit ripening, fruit color, fruit weight and size, seed weight, sugar and protein content, photosynthetic rate, chlorophyll content, plant height, flowering time, leaf senescence, root development, stomatal opening and closure, water-use efficiency, drought tolerance, heat stress tolerance, ethylene and abscisic acid sensitivity, and jasmonic acid content. The protein localizes to the cytosol, ER membrane, plastid, mitochondria, nucleus, and plasmodesmata. Studies of related genes in other species link the family to hypoxia response, herbivory resistance, and phosphorus deprivation tolerance.
