MYB60 — Sorghum bicolor

Summary

SORBI_3005G155900 (MYB60) encodes a Myb domain protein 60, a plant R2R3-MYB transcription factor that binds sequence-specific DNA and cis-regulatory regions. In sorghum, this gene is associated with the regulation of transport, stomatal movement, and responses to auxin and stress, including salinity and defence against fungi. It is linked to pigment accumulation, phlobaphene and flavonoid biosynthesis, lignin anabolism, and phytoalexin production, as well as anther wall tapetum development and reactive oxygen species metabolism. Associations with root system architecture and nuclear localisation have also been noted. Studies of related genes in other species link the family to phosphate homeostasis, leaf morphology, and transcriptional activation, while broader sequence similarity connections suggest associations with grain size, seed weight, plant height, drought tolerance, chlorophyll content, and lignin content.
