KAT1 — Daucus carota subsp. sativus

Summary

DCAR_004712 (DcKAT1) on carrot chromosome 1 encodes a thiolase family protein with 3-ketoacyl-CoA thiolase activity (EC 2.3.1.16) and protein binding capability. The gene is associated with fatty acid beta-oxidation, glyoxysome organization, jasmonic acid biosynthesis, green leaf volatile production, somatic embryogenesis, and response to wounding. It has been linked to abscisic acid signaling upregulation and phenylacetate breakdown. Localization evidence connects the product to the cytoplasm, endoplasmic reticulum, mitochondria, nucleolus, 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, 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.
