MYB — Sorghum bicolor

Summary

SbMYB (SORBI_3003G365600) on sorghum chromosome 3 encodes a protein with Myb and SANT domains and has DNA binding transcription factor activity, transcription cis-regulatory region binding, protein homodimerization activity, DNA binding, zinc binding, and protein binding. This gene is associated with negative regulation of abscisic acid biosynthesis, regulation of transport, post-embryonic plant organ morphogenesis, determination of dorsoventral asymmetry, histogenesis, cellular auxin homeostasis, transposition, pigmentation, gluconeogenesis, glutathione metabolism, phenylpropanoid metabolism, fruit development, response to absence of light, green leaf volatile biosynthetic process, lateral root development, response to sucrose, and detoxification. It has been linked to grain color, salt response, proline content, photosynthetic rate, chlorophyll content, photochemical quenching, plant height, grain yield, drought tolerance, and stress, biotic stress, drought stress, reproductive development, leaf, root, drought, reproductive, abiotic stress, ABA sensitivity, seed lipid biosynthesis, and salt stress tolerance. The encoded protein localizes to mitochondria, cytosol, and cytoplasm. Studies of related genes in other species connect the family to anther development, yield, and enhanced salt tolerance with increased ABA content.
