Phytic acid (PA) is a storage form of phosphorus in seeds. Phytase enzyme is activated at germination and hydrolyses PA into -inositol and inorganic phosphate. PA inhibits the absorption of minerals in the human intestine by chelation.

Low PA rice is beneficial because of its higher Zn bioavailability and it is suggested that the gene expression level of -inositol 3-phosphate synthase 1 () in developing grain is a key factor to explain the genotypic difference in PA accumulation among natural variants of rice. P fertilization is also considered to affect the PA content, but it is not clear how it affects gene expression and the PA content in different genotypes.

- Phytic acid (PA) is the main form of phosphorus storage in cereal and legume seeds, and low PA crops are developed to enhance nutrient availability and address environmental concerns.
- Researchers conducted genome-wide association mapping on rice variants to find the genetic factors influencing PA levels, identifying the INO1 gene as significant.
- The study revealed that PA accumulation and INO1 expression were higher in a high PA rice variant compared to a low PA variant, highlighting the importance of early gene regulation in determining PA content in rice.
