MYB — Sorghum bicolor

Summary

SORBI_3003G064200, designated SbMYB, encodes a protein with DNA-binding, RNA polymerase-binding and transcriptional co-regulator activities, localised to the nucleus. In sorghum, this gene is associated with the regulation of circadian rhythm, photoperiodic flowering, pigmentation, fruit development, phenylpropanoid and glutathione metabolism, gluconeogenesis, green leaf volatile biosynthesis, detoxification, histogenesis, transposition, and positive regulation of gene expression. It is linked to grain yield, grain colour, plant height, chlorophyll content, photosynthetic rate, photochemical quenching, proline content, flowering time, and responses to drought, salt and temperature stress. Studies of related genes in other species connect the family to circadian clock function, thermotolerance, cold stress response, anthocyanin biosynthesis, hypocotyl elongation, leaf area, biomass and photoperiodic flowering.
