MYB1 — Cucumis melo

Summary

MELO3C034442.2, also known as CmMYB1, encodes a MYB transcription factor with RNA polymerase II-specific DNA-binding and chromatin-binding activities. In melon, this gene is associated with the regulation of lignin and ethylene biosynthesis, starch and sucrose metabolism, fruit development and ripening, anther and pollen development, stomatal movement, and responses to auxin, cold, and salinity. It has been linked to sugar content, salt tolerance, and drought tolerance. The encoded protein localises to the nucleus, cytosol, and nuclear speckles. Studies of related genes in other species connect the MYB1 family to osmotic and salt stress tolerance, abscisic acid response, leaf and root development, tapetum development, and traits including grain size, fruit shape, anthocyanin content, and stomatal resistance.
