CKG — Solanum lycopersicum

Summary

SlCKG (SOLYC03G097820.2) encodes a bHLH_ZIP transcription factor with RNA polymerase II-specific DNA-binding and protein dimerization activities. Localized to the nucleus, this tomato gene on chromosome 3 is associated with chilling tolerance, phototransduction, negative regulation of phytochrome signaling, and positive regulation of gibberellin biosynthesis. It has been linked to hormone, flavonoid, carotenoid, and pigment metabolism, as well as iron transport, wound healing, and internode patterning. Associations with agronomic traits include fruit color and weight, petal color, leaf relative water content, carotenoid and anthocyanin content, proline content, germination rate, stomatal resistance, drought tolerance, and gibberellic acid content. Studies of related genes in other species link the family to organ growth, cell expansion, cell cycle progression, seed dormancy, and salt response.
