KAT1 — Cucumis melo

Summary

MELO3C020466.2 (CmKAT1) on melon chromosome 6 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, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, glyoxysome organization, phenylacetate breakdown, and response to wounding. It is linked to upregulation of abscisic acid-mediated signaling and localizes to multiple compartments including the ER, mitochondria, cytoplasm, nucleolus, and plant-type vacuole. Associations with stomatal regulation, potassium ion transport and channel activity, salt tolerance, water stress response, membrane potential modulation, flavonoid biosynthesis, inflorescence development, leaf senescence, and postgerminative growth have been reported. Studies of related genes in other species link the family to inward-rectifier potassium channel activity, guard cell ion flux, and potassium uptake.
