KAT1 — Daucus carota subsp. sativus

Summary

DCAR_001515 (DcKAT1) on carrot chromosome 1 encodes a thiolase-family protein with 3-ketothiolase activity and protein binding capability. The gene is associated with fatty acid beta-oxidation, jasmonic acid biosynthesis, green leaf volatile production, phenylacetate breakdown, and glyoxysome organization. It has been linked to somatic embryogenesis, embryogenesis, wound response, and upregulation of abscisic acid-mediated signaling. The product localizes to multiple cellular compartments including the ER, mitochondria, nucleolus, cytoplasm, and plant-type vacuole. Associations with stomatal regulation, potassium transport and channel activity, salt tolerance, water stress response, membrane potential modulation, and guard cell functioning have been reported. Additional connections include flavonoid biosynthesis, lipid metabolism, leaf senescence, inflorescence development, seedling growth in darkness, and postgerminative growth. Studies of related genes in other species link the family to inward-rectifier potassium channel activity, guard cell ion flux, and potassium uptake.
