MYB3 — Cucumis sativus

Summary

CsMYB3 (CSA_7G011815) on cucumber chromosome 7 encodes a MYB domain class transcription factor with DNA-binding, transcription cis-regulatory region binding, protein dimerization, and protein phosphatase activities. It is associated with regulation of flavonoid, anthocyanin, proanthocyanidin, lignin, and phenylpropanoid biosynthesis, as well as trichome differentiation and spacing, seed coat development, and response to iron ion starvation. The gene has been connected to fruit quality, leaf trichome density, anthocyanin content, flowering time, salt tolerance, cold acclimation, disease tolerance, and abiotic and biotic stress responses. Studies of related genes in other species link the family to UV-B tolerance, pathogen resistance, herbivore defense, lignin content, and root and fruit development traits.
