General Information

General Information Comment Organism
malfunction loss of this gene in itpk3-1 does neither affect phytate seed levels, nor seed Zn, Fe, and Mn but the micronutrient bioavailability is strongly reduced by seed phytate that forms complexes with seed cations. Low seed zinc is primarily caused by plant growth in Zn-deficient soil Arabidopsis thaliana
metabolism measurement of Fe, Zn, and Mn concentrations in seeds of Arabidopsis thaliana accessions grown in Zn-deficient and Zn-amended conditions, overview. Inositol 1,3,4-trisphosphate 5/6-kinase 3 gene (ITPK3), located close to a significant nucleotide polymorphism associated with relative Zn seed concentrations, is dispensable for seed micronutrients accumulation in ecotype Col-0 Arabidopsis thaliana
