KAT1 — Cucumis sativus

Summary

CsKAT1 (CSA_3G133140) in cucumber encodes a thiolase family protein with 3-ketothiolase activity (EC 2.3.1.16) and protein binding capability. The gene is associated with fatty acid beta-oxidation, the glyoxylate cycle, glyoxysome organization, and jasmonic acid and green leaf volatile biosynthesis. It has been linked to isoleucine and phenylacetate breakdown, detoxification, response to wounding, and upregulation of abscisic acid-mediated signaling. CsKAT1 is associated with salt tolerance, stomatal opening and closure, potassium ion transport and channel activity, guard cell functioning, and water stress response. Additional associations include flavonoid biosynthesis, leaf senescence, lipid mobilization, seedling growth, inflorescence development, and hypocotyl elongation. The protein localizes to the cytoplasm, endoplasmic reticulum, mitochondria, nucleolus, and plant-type vacuole. Related genes in other species link the family to inward-rectifier potassium channel activity, guard cell ion flux, and potassium uptake.
