MPS — Oryza sativa Indica Group

Summary

BGIOSGA006030 (symbol MPS, also known as OiMYB305 or OiMYB71) on chromosome 2 of Indica rice encodes a DNA-binding transcription activator with a Myb/SANT domain, belonging to the EOBI/EOBII-like plant family. The gene is associated with regulation of phenylpropanoid and shikimate metabolism, anthocyanin and pigment biosynthesis, cell wall organization, floral organ senescence, and responses to jasmonic acid, virus, and salinity. It has been linked to grain length, grain size, hull color, and photosynthetic rate. Studies of related genes in other species connect the family to traits including grain yield, seed weight, plant height, drought tolerance, chlorophyll content, and lignin content, as well as abscisic acid sensitivity and salt stress responses.
