• Seed-specific silencing of OsMRP5 reduces seed phytic acid and weight in rice.
• The OsMRP5 gene, of which mutations are known to reduce seed PA as well as seed yield and viability, was down-regulated specifically in rice seeds by using an artificial microRNA driven by the rice seed specific promoter Ole18
• Put together, the present study demonstrated that seed specific silencing of OsMRP5 could significantly reduce the PA content and increase Pi levels in seeds; however, it also significantly lowers seed weight in rice
• OsMRP5 is expressed in both vegetative tissues and developing seeds, and the two mutations do not change the level of RNA transcription
• A T-DNA insertion line, 4A-02500, in which OsMRP5 was disrupted, also showed the same high inorganic phosphorus phenotype as Os-lpa-XS110-3 and appeared to be homozygous lethal

• LPA1, OsMRP5, Mutations of the multi-drug resistance-associated protein ABC transporter gene 5 result in reduction of phytic acid in rice seeds., In this study, we mapped the XS-lpa2-1 gene to a region on chromosome 3 between microsatellite markers RM14360 and RM1332, where the rice orthologue (OsMRP5) of the maize lpa1 gene is located

• OsMIK, OsMRP5, Phytic Acid Contents and Metabolite Profiles of Progenies from Crossing Low Phytic Acid OsMIK and OsMRP5 Rice Oryza sativa L. Mutants., Progenies resulting from the cross of Os-lpa-XS110-1, a rice mutant carrying the myo-inositol (OsMIK) mutated gene, and Os-lpa-XS110-2 with the multi-drug resistance-associated protein ABC transporter gene 5 (OsMRP5) as mutation target, were subjected to high pressure ion chromatography
