Summary: In Peru, wheat is an important resource in the food industry but is mostly imported due to low harvested area. The quality of wheat flour was studied to ensure its suitability for bakery products. Commercial wheat flours had higher protein and gluten index compared to monovarietal wheat flours. Monovarietal wheat flours had higher gliadins and albumins/globulins and lower glutenin content. Baking strength was identified as the most important parameter for evaluating wheat flour quality. Overall, monovarietal wheat flours showed lower quality compared to commercial wheat flours.

Summary: Wheat, as a critical global food source, faces the pressure of climate change and the need for increased yield, quality, nutrition, and safety. However, the progress in understanding the composition and structure of gluten proteins has been slow due to the difficulty in characterizing intact functional glutenin polymer. The sub-cellular trafficking of gluten proteins and the timing of cellular events play important roles in gluten strength and function. Proteomics technologies offer new tools for studying gluten protein composition and identifying patterns that can improve its functionality.

Summary: High temperature affects the protein composition in wheat flour, leading to negative consequences on dough quality. A study was conducted to investigate the spatial variation in gluten subfractions in developing wheat ears under high night temperature (HNT). The results showed that HNT increased protein content, which negatively correlated with sedimentation volume (SV) for baking quality. Late-maturity genotypes exhibited more responsive changes in gluten subfractions under HNT.

Summary: Different concentrations of konjac glucomannan (KGM) had varying effects on the denaturation properties of frozen wheat gluten proteins, with a positive impact on gluten and gliadin, and a decrease in denaturation temperature and enthalpy of glutenin. The addition of KGM increased the alpha-helix structure of frozen gluten and gliadin, while decreasing that of frozen glutenin, indicating a potential interaction mechanism between KGM and the proteins. The scanning electron microscopy results confirmed the enhanced interaction between wheat proteins and KGM.

Summary: The structure of weed communities, including their composition, taxonomic diversity, and functional diversity, can explain the variability in crop quality. In this study, weed communities in 26 Spanish wheat fields managed either organically or conventionally were analyzed. The relationship between crop quality and weed community variables was examined, taking into account environmental factors. It was found that nitrogen fertilization, previous crop, and precipitation had significant effects on wheat grain protein concentration and composition. The impact of weed communities on grain quality was limited, with only a small increase in the model's explanatory power. Understanding the mechanisms behind weed effects on crop quality can help in designing sustainable weed management practices.

Summary: Selenium's classification as an essential nutrient for plant growth is still uncertain, but its role in human health is important due to its impact on the production of primary and secondary metabolites. Low levels of selenium have been linked to cancer and cardiac diseases. Enriching crops with selenium has been established as a pioneering strategy to increase selenium intake in animals and humans. Studies have shown that selenium biofortification can increase selenium levels in plant tissues without affecting productivity or quality. However, the accumulation of selenium in plants needs to be quantified and balanced, as it may affect nutrient balance. This timely review provides an overview of the metabolic changes induced in plants by selenium enrichment, and highlights the contrasting effects on various secondary metabolites.

Summary: Some wheat cultivars exhibit a linear relationship between grain protein concentration (GPC) and baking volume, while others show a saturation curve. High nitrogen application in pot experiments can reliably achieve GPC > 17%, which is not commonly attained in field conditions. The specific effects of nitrogen on grain protein composition and its relationship with baking volume were investigated in four wheat cultivars. Increasing nitrogen levels resulted in varying changes in grain protein fractions and baking volume in different cultivars.

Summary: Sulfur deprivation in plants has a significant impact on membrane lipids, resulting in abiotic stress. Different levels of sulfur were used to identify individual thylakoid membrane lipids in lettuce plants. LC-ESI-MS/MS was used to analyze the changes in lipids and understand the plant's response to stress. The results showed transformations in glycolipids, increased lipid saturation, and higher levels of oxidized SQDG under sulfur-limiting conditions. The oxidized SQDG could potentially serve as a marker for other abiotic stress factors.

Summary: Waterlogging has a significant impact on plant growth and development, leading to reduced yield. Supplementing high sulphur (S) levels can alleviate the adverse effects of waterlogging stress on oilseed rape by improving growth and yield through enhanced antioxidant activities. However, under normal conditions, high S levels do not provide additional benefits compared to medium S application. Therefore, additional S supplementation can be employed as a potential strategy to mitigate the negative effects of waterlogging stress.

Summary: Meta-analysis of 50 articles found that the use of nitrification inhibitors (NIs) can increase crop yield and soil NH4+ concentrations, while reducing N2O emissions and soil NO3- concentrations, with no effect on ammonia volatilization. The effectiveness of NIs in tropical agroecosystems in Brazil is similar to previous meta-analyses conducted in temperate climates, indicating that NI application is an efficient strategy to delay nitrification and mitigate N2O emissions.

Summary: Foliar fertilisation is an important technique in agriculture, but the mechanisms of foliar uptake are not well understood. In this study, tomato and pepper plants with different leaf surface traits were used to investigate the importance of leaf surface features for foliar phosphorus (P) uptake. The results showed that the presence of trichomes on tomato leaf veins contributed to increased P concentration, while the abaxial side of pepper leaves had the highest P absorption rate. These findings suggest that different leaf parts play unequal roles in the absorption of foliar-applied agrochemicals.

Summary: This study investigated the organic phosphorus use efficiency of eight varieties of faba bean. The results showed that although plants grown with organic phosphorus and inorganic phosphorus produced similar amounts of dry matter, the phosphorus uptake by inorganic phosphorus-fertilized plants was twice as high as that by organic phosphorus-fertilized plants. Additionally, significant differences were observed between organic phosphorus and inorganic phosphorus in terms of nodulation characteristics and phosphorus utilization efficiency. Among the tested varieties, Tiffany had higher organic phosphorus utilization efficiency and organic phosphorus beneficiary factor.
