DCE — Solanum tuberosum

Summary

StDCE (PGSC0003DMG400013331) on potato chromosome 11 encodes a pyridoxal-phosphate-dependent decarboxylase with glutamate decarboxylase and sphinganine-1-phosphate aldolase activities, and binds calmodulin and calcium ions. The gene is associated with glutamate and sphingolipid breakdown, GABA formation, and responses to nitrogen starvation, mechanical stimulus, stress, and adventitious root development. It has been linked to traits including seed weight, shoot growth angle, photosynthetic rate, chlorophyll content, stomatal opening and closure, leaf senescence, flowering time, and abscisic acid and ethylene sensitivity. Associations with drought tolerance, bacterial pathogen resistance, heat stress tolerance, water-use efficiency, and salt tolerance have also been reported. The encoded protein localises to the cytosol, nucleus, plastid, mitochondria, ER membrane, and plasmodesmata. Studies of related genes in other species connect the family to hypoxia response, herbivory resistance, and fruit ripening.
