MYB3 — Oryza sativa Indica Group

Summary

BGIOSGA037085 (MYB3, also known as OiMYB3) on chromosome 12 of Indica rice encodes a plant Myb 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, circadian rhythm, ABA signalling, and responses to wounding and iron ion starvation. The gene has been linked to grain length and size, hull colour, flowering time, salt and oxidative stress tolerance, disease tolerance, root morphology, plant growth and development, osmotic response sensitivity, and pollen fertility restoration. Related genes in other species are associated with abiotic stress, abscisic acid and osmotic stress responses, flavonol and phenylpropanoid biosynthesis, and fungal resistance.
