Summary: Currently, whole grains are obtained by adding bran and middlings to refined flours, resulting in variations in the ratio of endosperm, bran, and germ. This study identifies specific lipid markers in different debranning fractions of Italian and Canadian durum wheat blends, which have high content of monounsaturated fatty acids, tocopherols, and sterols. Palmitic acid, oleic acid, tocopherol isomers, and total sterols could be useful biomarkers for evaluating the grain-to-tissue ratio in recombined flours.

Summary: Enriching semolina bread with prebiotic ingredients like beta-glucans can have health benefits. This study investigated the effects of adding varying amounts of thin bran or barley flour to wheat semolina bread. The results showed that the inclusion of barley flour or thin bran increased water absorption and dough stability, but also increased dough development time. The specific volume and hardness of the bread decreased, while beta-glucan levels increased. The study concludes that barley flour or thin bran have potential as ingredients to increase beta-glucan intake, but further research is needed for improved quality features.

Summary: The integration of high-throughput phenotyping and metabolic approaches is an effective strategy to study the relationship between genotype and environment in crop improvement. This study focused on the phenotypic and metabolic traits related to grain yield and quality at canopy and organ levels in durum wheat varieties. The results showed that low nitrogen supply affected the coordination of carbon and nitrogen, leading to a reduction in grain yield and nutrient composition. Furthermore, the activities of key enzymes and sucrose content in ear organs were found to be positively associated with grain yield and quality.

Summary: This study used durum wheat debranning fractions (fine and coarse bran) as an ingredient in whole-meal spaghetti formulation to investigate their chemical-nutritional characteristics, specifically folate levels and sensory properties. The experimental pasta had higher folate content (40.5 μg/100 g) than commercial whole-meal pasta (28.3 μg/100 g), meeting the health claim requirements for folate (Reg. EU 432/2012) and dietary fiber nutritional claim. After cooking, pasta formulated with coarse bran retained 80% of folate and received good sensory acceptability. This suggests that whole-meal pasta formulated with folate-rich debranning fractions can serve as a natural functional food, potentially improving population health when integrated into the diet.

Summary: This study investigated the impact of extreme high-temperature stress on wheat grain yield and quality, focusing on grain protein concentration as a key factor. The research found that high-temperature stress significantly reduced total above-ground nitrogen and accelerated grain nitrogen accumulation, with more sensitivity at anthesis compared to grain filling. The study also enhanced a crop model to better simulate nitrogen dynamics and grain quality under high-temperature stress, reducing uncertainties in assessing climate change effects on wheat grain quality.

Summary: Currently, increasing the micronutrient densities in maize is a top priority for breeders. The study found significant variations in grain zinc and iron concentration among the hybrids, with the zinc-enhanced quality protein maize showing the highest concentration. Different environments also resulted in significant differences in grain zinc and iron concentration, suggesting the potential to develop micronutrient-rich varieties for specific environments. Furthermore, there was a positive and highly significant correlation between grain zinc and iron, indicating the possibility of improving both traits simultaneously. However, there was a moderate negative correlation between grain yield and grain zinc/iron concentration, suggesting slight dilution effects.

Summary: During drought stress, Zn deficiency leads to inactivation of many enzymes in plants. Zn application and AMF-wheat symbiosis have been found to enhance plant tolerance to drought stress. This study investigated the effects of Zn and AMF on various aspects of plant growth and physiological responses in wheat under drought conditions. The results showed that Zn and AMF treatments improved plant growth and yield attributes, increased protein content, RWC, and HI, and enhanced antioxidant activities and GB accumulation. These findings suggest that Zn and AMF can enhance the antioxidant defense and ionic attributes of plants under abiotic stress.

Summary: Iron and zinc enrichment of staple crops through biofortification can help alleviate micronutrient deficiency in sub-Saharan Africa. A mating design was used to determine the combining ability and heterosis for grain yield, iron, zinc and phytic acid concentration in maize. Both additive and non-additive gene effects were important in controlling these traits under different nitrogen conditions. Some hybrids showed high and significant positive combining ability effects for grain yield, iron and zinc content under low nitrogen conditions, indicating potential heterosis in these traits. Certain lines and testers were identified as good general combiners for iron, zinc and grain yield, and can be used as parents in maize breeding programs to develop high-yielding genotypes with high iron and zinc content.

Summary: Genetic diversity is crucial for crop improvement, especially in indigenous grain legume crops like cowpea. Cowpea has the potential to improve food security and income for resource poor famers in sub-Saharan Africa. However, limited progress has been made in drought tolerance research due to the complexity of this trait and the involvement of numerous genes that are affected by environmental conditions. Therefore, it is important to review the nutritional, phenotypic, and genotypic diversity of cowpea and understand the importance of diversity in breeding for complex traits such as drought tolerance and yield. Additionally, omics tools are important for drought tolerance breeding and cultivar development in cowpea.
