Annotated Information
Gene Symbol
- Os02g0819400 <=> lpa1
Function
- OsLpa1 represents a novel gene involved in phytic acid metabolism.
Mutant
- This mutant exhibits a 45% reduction in rice seed phytic acid with a molar-equivalent increase in inorganic phosphorus; however, it does not appear to diVer signiWcantly in productivity from its wild-type progenitor. A second lpa1 mutant was identiWed from additional screening for high seed inorganic phosphorus phenotypes. Using a positional cloning strategy, we identiWed a single candidate gene at the rice Lpa1 locus. Sequence analysis of the candidate gene from the lpa1 mutants revealed two independent mutations (a single base pair substitution and a single base pair deletion) that conWrmed the identiWcation of this candidate as the rice low phytic acid 1 gene, OsLpa1.
