MYB3 — Cucumis sativus

Summary

CsMYB3 (CSA_2G270220) on cucumber chromosome 2 encodes a Myb-domain transcription factor with DNA-binding, protein-dimerization, and small GTPase-binding activities, as well as protein phosphatase activity. It is associated with the regulation of flavonoid, anthocyanin, proanthocyanidin, lignin, and phenylpropanoid metabolism, and with trichome differentiation and spacing, seed coat development, and response to iron starvation. The gene has been linked to fruit quality, leaf trichome density, flavonoid and anthocyanin content, brassinosteroid and jasmonic acid content, flowering time, and responses to UV-B, low temperature, oxidative stress, salt, and biotic stress. Studies of related genes in other species connect the family to lignin biosynthesis, trichome development, anthocyanin pigmentation, and tolerance to UV-B, cold, and pathogens.
