MYB — Sorghum bicolor

Summary

SbMYB (SORBI_3010G004300) on sorghum chromosome 10 encodes a protein with a MYB domain, SANT domain, and homeodomain-like superfamily, with DNA-binding and transcriptional co-regulator activities, localised to the nucleus. The gene is associated with regulation of circadian rhythm, photoperiodism and flowering, as well as pigmentation, phenylpropanoid metabolism, fruit development, and green leaf volatile biosynthesis. It is linked to grain color, grain yield, plant height, chlorophyll content, photosynthetic rate, and responses to drought, salt, and temperature stress. Studies of related genes in other species link the family to circadian clock gene expression, hypocotyl elongation, thermotolerance, cold stress response, and photoperiodic flowering time.
