KAT1 — Daucus carota subsp. sativus

Summary

DCAR_008931 (DcKAT1) on carrot chromosome 3 encodes a protein with 3-ketothiolase activity and protein binding, belonging to the thiolase-like and FADA-like families. The gene is associated with fatty acid beta-oxidation, jasmonic acid anabolism, green leaf volatile biosynthetic process, somatic embryogenesis, and response to wounding. It is linked to glyoxysome organization, phenylacetate breakdown, and upregulation of abscisic acid mediated signaling. Associations include stomatal opening and closure, potassium transport and channel activity, guard cell functioning, salt tolerance, water stress response, and membrane potential modulation. The gene is also connected to flavonoid biosynthesis, lipid mobilization and metabolism, leaf senescence, seedling growth in darkness, hypocotyl elongation, and inflorescence development. Localization evidence links the product to the ER, mitochondria, cytoplasm, nucleolus, and plant-type vacuole. Studies of related genes in other species connect the family to potassium uptake, guard cell ion flux, and sucrose-dependent germination.
