MPS — Oryza sativa Indica Group

Summary

BGIOSGA014750 (MPS, OiMPS) encodes a R2R3-MYB transcription factor with DNA-binding transcription activator activity, localised to the nucleus and plant-type cell wall. In indica rice, this gene is associated with regulation of phenylpropanoid and shikimate metabolism, anthocyanin and pigment biosynthesis, anther and pollen development, floral organ senescence, cell wall organisation, circadian rhythm, and responses to jasmonic acid, salinity, thirst, and virus. It has been linked to grain length, grain size, hull color, and photosynthetic rate. Studies of related MYB71 and MYB79 genes connect the family to abiotic stress response and abscisic acid sensitivity. Sequence similarity with related genes in other species links the family to traits including grain yield, seed weight and size, plant height, drought and heat tolerance, chlorophyll and flavonoid content, lignin and starch content, and root and leaf morphology.
