Societal Impact Statement Rice is a critical crop for the delivery of calories and essential micronutrients to human diet. Biofortification rice with zinc (Zn) iron (Fe) aims combat health issues associated “hidden hunger”. Arbuscular mycorrhizal (AM) fungi have been explored their potential enhance Zn Fe uptake in products. However, phytate, an anti‐nutritional compound rich phosphorus (P), reduces bioavailability cereals. We investigated how AM fungal Zn, P interacts affect found tends lower micronutrient than non‐mycorrhizal. Summary Micronutrients such as play crucial role health. In humans, ability be absorbed digestive system (i.e., bioavailability) hindered by phytate. Accumulation phytate aleurone layer cereal grains affected soil characteristics, particularly availability (P). take up great amounts P, but also some into host plant. this study, we impact grain gene expression under aerobic, controlled‐environment growing conditions. Five varieties were grown or without inoculation ( Rhizophagus irregularis ), two availabilities. Samples developing taken RNAseq analysis. At plant maturity, nutrition was examined on total concentration basis, specifically Synchrotron x‐ray fluorescence microscopy. The effect positive when only considered, negative whole concentrations. AM‐colonised plants accumulated more compared non‐AM plants, leading overall bioavailability. Indirect effects small. colonisation dependent whether grain, layer, quantified. This has implications consumption vs milled products humans.
