  • The article is open access: https://nph.onlinelibrary.wiley.com/doi/10.1002/ppp3.70051

    Summary

    • Bread wheat, the world’s second major food crop, is crucial for global nutrition. Enhancing Zn and Fe bioavailability in wheat grain can combat human nutritional deficiencies. There is demonstrated potential for AM fungi to support these goals through increased uptake of Zn and Fe into wheat. However, AM fungi can also increase P uptake, leading to higher phytic acid levels in the grain, which can hinder Zn and Fe absorption in the digestive system.
    • Eight Australian wheat varieties were grown with or without AM fungi (Rhizophagus irregularis) and two soil P treatments (addition of 0 or 25 mg P kg−1 soil) in a controlled growth environment. At maturity, plants were harvested and analysed for grain biomass, nutrition, phytate and 2D spatial elemental distribution within grain using X-ray Fluorescence Microscopy.
    • Our results indicated that the AM-colonised plants had greater grain biomass and accumulated greater amounts of P and Zn in whole grain and Zn in the aleurone layer, but not Fe. Increased P did not raise phytate levels, leading to overall higher Zn and Fe bioavailability in AM-inoculated plants compared to non-inoculated controls.
    • AM fungal inoculation could be a promising strategy for producing wheat grain with higher micronutrient bioavailability for human nutrition, without compromising agronomic practices (P fertiliser application) or yield targets.







  • Are the parts both made of PLA? Silicone caulking would be elastic and easy to break but it might also become unstuck on its own since the adhesion to plastics is not great.

    Rubber cement would also work in principle but it might not be reversible at all and depending on the solvent and what plastics you used it might damage the plastic parts while the solvent is drying. Acetone can damage ABS plastics for instance.

    Would a low-temp hot melt gun work? They can operate as low as 120°C which might be low enough to not destroy the plastic parts.
