Summary: More than one-third of the global population suffers from iron and zinc deficiency, especially in developing countries. This study focuses on the investigation of variability and bioavailability of iron and zinc in bread wheat. The study found that phytic acid is the main factor reducing the bioavailability of these micronutrients, and drought also affects their accumulation in wheat. A pre-breeding wheat germplasm set comprising 137 genotypes was used to assess the variability of iron, zinc, and phytic acid content. Promising genotypes with low phytic acid and high iron and zinc content were identified for further breeding of biofortified wheat cultivars.

Summary: Rice is a staple food for billions of people and its bioavailability of iron and zinc is affected by phytic acid. A study found that while a genotype with high iron content had low bioavailability, possibly due to its high phytic acid content. Phytic acid mainly affects the bioavailability of iron, but has less effect on zinc, which is evenly distributed in the rice grain. The study also identified genes related to phytic acid synthesis and grain-specific phosphorus transporter genes that are expressed during grain filling and correlated with phytic acid accumulation. This research provides insights for breeders to develop rice genotypes with higher bioavailability of iron and zinc by targeting phytic acid related genes.

Summary: This study investigated the possibility of using phytic acid to remove iron in zinc hydrometallurgy. Results showed that at pH = 2.1, up to 99.5% of iron could be removed with a loss of zinc equal to 0.6%. Even though the amount of residue is higher, iron phytate could be stored in less drastic conditions than jarosite.

Summary: This study compared the effects of low phytate soymilk and regular soymilk consumption on long-term mineral status using rodent models. The results showed that both soymilk and low phytate soymilk increased serum calcium, hemoglobin, transferrin, and femur zinc levels compared to the control group. However, the soymilk group had decreased serum iron, red cell distribution width, and zinc levels. In addition, the low phytate soymilk group had significantly higher serum and liver zinc levels compared to the soymilk group. Furthermore, low phytate soymilk improved bone quality, maintained circulating iron and zinc levels, and increased liver iron storage compared to regular soymilk. Further studies on human subjects are needed to explore the effects of low phytate soymilk consumption on calcium, iron, and zinc status.

Summary: Arabidopsis plants exposed to kanamycin show altered metal homeostasis, and mutation of the WBC19 gene leads to increased sensitivity to kanamycin and changes in iron and zinc uptake. A dynamic compartment model was constructed based on a transport and interaction diagram and was parameterized using experimental time series data. The model provides novel insights into metal homeostasis and explains differences in data from wildtype, mutants, and kanamycin inhibition experiments.

Summary: Zinc is an essential micronutrient for humans, and insufficient dietary intake is the leading cause of zinc deficiency, especially in populations consuming cereal grains as a staple food. Research has shown that the absorption, transport, and deposition of zinc in small-grained cereals are influenced by various factors, including plant zinc transporters and metal chelators.

Summary: Wheat is an important source of minerals for a healthy diet, but the phytate complex in the grain makes some minerals unavailable to humans. Our trials compared different wheat species and bread-making recipes to find ways to reduce phytic acid content and increase mineral bioavailability. We found significant variations in mineral content and phytase activity among different wheat species and varieties. Bread-making recipes, such as long yeast proofing or the use of whole grain rye flour, had a greater impact on reducing phytic acid content in bread than the choice of wheat species. Collaborations between research organizations and stakeholders are necessary for optimizing food production for a growing world population.

Summary: Rice is a vital source of calories and mineral nutrients, but the accumulation of essential and toxic elements in rice grain remains poorly understood. This study analyzed the temporal changes in dry matter, elemental concentrations, and gene expression during grain development. Three distinct patterns of element accumulation were observed, which can be attributed to differences in soil behavior, nutrient redistribution, gene expression, and sink-source relationship.

Summary: Dimethylarsenate (DMAs(V)) is a common arsenic species in soils and plants that can cause straighthead disease in rice. This study found that the phytotoxicity of DMAs(V) may be due to the presence of the more toxic trivalent dimethylarsenite (DMAs(III)), which can be produced by anaerobic bacteria and rice plants.

Summary: Plants take up various trace metals from soil, some of which are essential but become toxic at high concentrations, while others are non-essential and toxic even at low concentrations. Soil contamination of trace metals due to human activities is a global problem. This contamination can cause toxicity and growth inhibition in plants, as well as threaten food safety and human health. Understanding the mechanisms of trace metal toxicity and plant response is crucial for improving plant growth and food safety in contaminated soils.

Summary: The concentration, chemical speciation, and spatial distribution of essential and toxic mineral elements in cereal seeds have significant implications for human health. X-ray fluorescence microscopy (mu-XRF) is used to identify genes responsible for element uptake, translocation, and storage, and an ImageJ-based pipeline is developed for spatial distribution analysis. This method is applied in rice seeds and diverse rice accessions, identifying loci and mutants associated with the spatial distribution of elements and providing a basis for investigating the genetics and molecular mechanisms controlling mineral elements in plant seeds.

Summary: Grassland biomes provide important ecosystem services through nutrient cycling, with organic phosphorus (Po) being a significant component of soil phosphorus. This study analyzed soil metagenomes from different grassland biomes worldwide to investigate the distribution and abundance of key P enzymes and their relationship with environmental factors. The results showed that alkaline phosphatase phoD was the most abundant P enzyme gene, followed by acid phosphatases Nsap-A and Nsap-C. pH, T-max, SOC, and soil moisture were found to be associated with the abundance and diversity of all studied genes, and the presence of certain genes correlated with specific soil properties.

Summary: We collected 14 rice samples from Cd contaminated areas and determined the Cd relative bioavailability (RBA) in rice using in vivo mouse bioassay. Cd-RBA in rice correlated positively with calcium and amylose content but negatively with the concentrations of sulfur, phosphorus, phytic acid, and crude protein. Based on the total and bioavailable Cd concentrations in rice, weekly dietary Cd intake for adults was estimated. This study demonstrates the possibility of predicting Cd-RBA based on rice compositions and provides valuable suggestions for health risk assessment.

Summary: In this study, a novel approach utilizing a bacterial biosensor in conjunction with amylase hydrolysis was developed for high-throughput detection of inorganic arsenic (iAs) in rice grains. The biosensor demonstrated high specificity and was able to distinguish between arsenite [As(III)] and arsenate [As(V)]. The results obtained using this method were comparable to the standard technique of microwave digestion coupled with HPLC-ICP-MS. The biosensor exhibited excellent reproducibility and a high signal-to-noise ratio, with lower limits of detection than the maximum allowable level for infant rice supplements established by the European Union.
