Summary: The rapid increase in population growth under changing climatic conditions causes drought stress, threatening world food security. The identification of physiological and biochemical traits acting as yield-limiting factors in diverse germplasm is pre-requisite for genetic improvement under water-deficit conditions. The major aim of the present study was the identification of drought-tolerant wheat cultivars with a novel source of drought tolerance from local wheat germplasm.

Summary: In this study, 55 wheat cystatins (TaCystatins) were identified and divided into three groups based on conserved gene structures and peptide motifs. Homoeolog analysis showed that both homoeolog retention percentage and gene duplications contributed to the abundance of the TaCystatin family. Codon usage pattern analysis revealed evident codon usage bias in TaCystatins mainly affected by mutation pressure.

Summary: This study evaluated the mineral composition of different wheat varieties, finding higher concentrations of minerals in bran and whole grain flour, especially potassium and magnesium. The results suggest that some samples meet the conditions for approved health claims, potentially supporting the classification of wheat flour as functional foods.

Summary: The study concludes that pre-sowing silicon treatment can significantly improve the morpho-physiological and biochemical characteristics of wheat under drought and heat stress. Silicon treatment also enhances the abiotic stress tolerance of wheat by increasing antioxidant activity and osmolyte concentration, and improving water stress indices.

Summary: In this study, 18 TaCHYR genes were identified and classified in wheat. The results showed that these genes play important roles in the growth, development and stress responses of wheat. The expression of certain TaCHYR genes inhibited the growth of yeast cells under salt and dehydration stress. Furthermore, gene ontology annotation, protein interaction and miRNA regulatory network analysis provided candidate genes for further functional investigations.

Summary: This study presents the first report on the phylogenetic relationships and chemotype diversity of Fusarium strains in Paraguay. The dominant chemotype of the Fusarium graminearum species complex (FGSC) strains isolated from wheat fields in Paraguay was found to be 15-ADON. The study also identified other Fusarium species, including F. asiaticum, F. meridionale, and F. cortaderiae.

Summary: The genetic architecture of resistance to spot blotch in wheat was investigated through a Genome-Wide Association Study (GWAS) involving 303 diverse genotypes. The study evaluated the association panel at two different locations in India and recorded phenotypic data for two consecutive years. After analysis, seven important marker-trait associations were identified for marker-assisted selection.

Summary: This study identified a new wheat-Dasypyrum villosum translocation line that exhibits stable resistance to wheat sharp eyespot. The introgression of this translocation line into wheat cultivars significantly enhanced their resistance. Through sequencing and marker development, the translocated chromosome can be traced and detected. These findings provide novel germplasm and technological tools for wheat breeding.

Summary: This study conducted transcriptomic and proteomic analysis to reveal the differentially expressed genes and proteins in wheat spikes treated with PHS. Results showed differences in spliceosome and proteasome pathways between PHS-sensitive and tolerant cultivars, with alternative splicing and ubiquitin-proteasome supporting germination and seed dormancy regulation. The findings provide insight into the mechanisms and pathways related to PHS in wheat.

Summary: This study evaluated the leaf rust resistance of 50 Egyptian wheat varieties and identified 28 leaf rust resistance genes within the germplasm collections. Most varieties showed high to moderate levels of resistance, with some displaying fast rusting behavior. 21 out of 28 tested Lr genes were successfully identified, including only five genes conferring adult plant resistant or slow rusting behavior in the Egyptian collection.

Summary: The study sequenced 242 accessions of Aegilops tauschii and identified a rare lineage contributing to the wheat D subgenome. Through association mapping, genomic regions with candidate genes for disease and pest resistance were identified and successfully transferred into wheat. Exploiting the genomic diversity of the wild progenitor allows for rapid trait discovery and functional genetic validation.
