KAT1 — Cucumis melo

Summary

MELO3C006334.2, also known as CmKAT1, encodes a thiolase family protein with 3-ketothiolase activity (EC 2.3.1.16) and protein binding capability. This melon gene on chromosome 7 is associated with fatty acid beta-oxidation, glyoxysome organization, jasmonic acid and green leaf volatile biosynthesis, and response to wounding. It has been linked to stomatal regulation, potassium ion transport, salt tolerance, and water stress response. Additional associations include leaf senescence, inflorescence development, and postgerminative growth. The encoded protein localizes to multiple cellular compartments including the cytoplasm, endoplasmic reticulum, mitochondria, nucleolus, and plant-type vacuole. Studies of related genes in other species link the family to potassium uptake, guard cell ion flux, and sucrose-dependent germination and seedling establishment.
