MYB3 — Oryza sativa Indica Group

Summary

BGIOSGA004902 (MYB3, also known as OiMYB3) on chromosome 1 of indica rice encodes a Myb-family transcription factor with DNA-binding and protein phosphatase activity, localised to the nucleus. It is associated with the regulation of phenylpropanoid, lignin, anthocyanin, and cinnamic acid metabolism, the shikimate pathway, secondary cell wall biogenesis, pigmentation, green leaf volatile biosynthesis, and responses to wounding, iron starvation, and ABA signaling. The gene is linked to grain length and size, hull color, flowering time, root morphology, salt and oxidative stress tolerance, disease tolerance, and osmotic and abscisic acid sensitivity. Studies of related genes in other species connect the family to phenylpropanoid and flavonol biosynthesis, abiotic and osmotic stress responses, and Verticillium wilt resistance.
