Summary: This study investigates the formation of films using polyelectrolyte complexes (PECs) of xylan and polyethylenimine (PEI). The mass ratio and pH value of xylan/PEI have an impact on the size and properties of the complexes. The neutralization charge ratio depends on pH. The film properties are affected by the composition and the method used to prepare the films. Dynamic mechanical thermal analysis shows that the glass transition temperature (T-g) of the films is influenced by composition.

Summary: This study identified two major quantitative trait loci (QTLs) for swollen root formation in turnip, FR1.1 and FR7.1, and narrowed down a major QTL region to 220 kb containing 47 putative genes. Candidate gene Bra003652, a homolog of AT1G78240 in Arabidopsis thaliana, was suggested to play a crucial role in swollen root formation. These findings may provide new insights into the molecular mechanism of swollen root formation in root crops.

Summary: By utilizing SSR and SLAF-seq technologies, this study successfully mapped QTLs for flowering time in rapeseed and identified three target intervals. A total of 186 genes with genetic variations, including 14 related to flowering time pathways, were found in these intervals. Development of six InDel markers linked to flowering time indicates the credibility of the results for further genetic studies in Brassica napus L.

Summary: This study identified two QTLs related to Verticillium wilt resistance in cotton through BSA-seq analysis, and screened a series of candidate genes in the qvw-D05-2 region by SnpEff analysis. Further investigation showed that GhDRP is involved in resistance to V. dahliae infection, as silencing this gene resulted in higher susceptibility of plants.

Summary: This study identified 11 SNPs and 3 QTLs associated with ear diameter in maize through a GWAS and linkage analysis. A major QTL on chromosome 1 was co-identified near the Zm00001d030559 gene. The candidate genes and SNPs identified provide insights into the genetic mechanism of ear diameter formation in maize and can be used for future research and genetic improvement of maize yield through marker-assisted breeding.

Summary: In this study, genotyping analysis was conducted on Suhuai pigs using the Neogen(R) GGP Porcine 80 K SNP array to identify candidate genes affecting the number of ribs and carcass length. Significant SNP markers were detected on specific chromosomes, and both known and novel QTL were identified. Functional candidate genes for these traits were also proposed based on their biological functions.

Summary: The end-use value of wheat flour is determined by the concentration and composition of storage proteins. Monitoring the gliadin to glutenin ratio is important for maintaining end-use quality, but the measurement of this ratio is costly and time consuming. In this study, genomic selection (GS) was applied to the gliadin to glutenin ratio and a model was developed to predict this trait. The model's predictive ability depended on the composition of the training population and could be improved by optimizing the population. The results showed that GS can efficiently predict the gliadin to glutenin ratio and previous generations' data can be useful for training the model.

Summary: Nitrogen deficiency and heat stress are major abiotic stresses that affect wheat grain quantity and quality. This study examined wheat varietal response to nitrogen and heat stress, and found that RSI and RNDVI were strongly correlated with grain yield, suggesting their potential use as efficient selection criteria for nitrogen-use-efficient wheat varieties under terminal heat stress conditions.

Summary: Spelt wheat, an underexploited hexaploid wheat species, has gained popularity as a raw material in bakery products. This study examined the physical, compositional, and breadmaking quality traits of 90 spelt genotypes. The findings showed that spelt has higher protein and gluten content but weaker dough strength and stability compared to common bread wheat. Furthermore, several genebank accessions and international cultivars were identified as potential genetic resources for improving spelt's breadmaking qualities.

Summary: Wheat grain storage proteins and alpha-amylase trypsin inhibitors in bread wheat are only partially digested, making them potential triggers of non-celiac wheat sensitivity. A study on the digestibility of bread wheat proteins revealed variable levels of proteolysis after in vitro digestion, with no major plant trait correlated to protein digestibility in high grain protein content cultivars. However, the protein digestibility of bread from high yield cultivars was influenced by protein composition and genetic distance from a reference variety. Breeding for highly digestible proteins in high yield wheat varieties could help reduce adverse reactions to wheat proteins in susceptible individuals.

Summary: Improving seed protein quality by stabilizing sulfur nutrition is of great importance for food and agroecological transitions. Sulfur is crucial for the synthesis of sulfur-rich proteins in seeds, and its deficiency negatively impacts protein composition, leading to health problems in humans. Sulfur also plays a key role in stress tolerance. Recent studies have made significant advances in understanding the interaction between sulfur nutrition and environmental or nutritional stresses, metabolic pathways to mitigate stress impacts on seed protein quality, and the regulation of seed protein composition through sulfur homeostasis.
