Summary: Aegilops tauschii, the D-genome donor of bread wheat, is a genetic resource with a large diversity of morpho-physiological traits and adaptations to a wide ecological range. Through genome-wide association studies, markers or genes associated with morpho-physiological traits were identified, revealing differences in genetic diversity between different lineages, which are valuable for wheat breeding.

Summary: This study used GBS technology to analyze wild and domesticated tetraploid wheat, finding misclassification and redundancy. By determining the center of genetic diversity, a core set was generated that preserved over 93% of the available diversity. The study found that wild germplasm showed more differentiation than domesticated accessions, providing sufficient diversity for crop improvement.

Summary: The study identified the donor of the common wheat B subgenome as a distinct and most likely extinct diploid species, differing from the still existing Aegilops species. It also found interspecific genetic introgressions during the evolution of the Triticum/Aegilops species complex. These newly assembled genome resources offer a new avenue for wheat improvement.

Summary: Wild relatives of modern crops are promising sources of genetic variation for climate change adaptation. This study investigated the natural variation in leaf hair density (LHD) among 293 Ae. tauschii accessions and performed genome-wide association studies in two lineages. The results revealed faster and more independent evolution of LHD in TauL2 compared to TauL1. The majority of candidate genes associated with LHD are involved in biotic and abiotic stress responses.

Summary: Late blight, caused by Phytophthora infestans, is a devastating disease in potato-producing regions. Cultivation of resistant varieties and identification of germplasms with late blight resistance are effective ways to control the disease. A diverse population of 189 genotypes was screened for resistance, revealing broad-spectrum and isolate-specific resistant resources. Genetic analysis found abundant variation, with differentiation among populations and potential for gene improvement in breeding programs. Results provide valuable information for cultivar improvement and resistance gene mining.

Summary: Intraspikelet differences in grain size and seed dormancy in wild emmer wheat were found to be controlled by genetic factors. Wild emmer populations consist of genotypes with varying degrees of dormancy, and the genetic control of seed dormancy may be independent of intraspikelet grain size differences.

Summary: The genetic improvement and enhancement of plant performance in durum wheat largely rely on stable QTL identification and closely linked molecular markers. This study conducted a comprehensive meta-QTL analysis on 45 traits of durum wheat, identifying a total of 368 QTL distributed across all 14 chromosomes of genomes A and B. These QTL were further grouped into 85 meta-QTL (MQTL), with quality-related traits having the highest number of QTL, followed by abiotic and biotic stress-related traits. This work will aid in the development of new cultivars with specific quantitative traits and accelerate breeding programs.

Summary: This study examined the genetic variability in grain beta-glucan, pentosan, and protein content in Aegilops biuncialis and identified 34 QTLs associated with these traits. Mapping the markers to chromosome assemblies identified the role of genes on certain chromosomes in the formation of grain beta-glucan content. The QTLs and genes identified in this study are potential targets for improving the health-promoting properties of wheat-derived foods.

Summary: Stem rust, caused by the fungus Puccinia graminis f. sp. tritici (Pgt), is a devastating fungal disease affecting wheat worldwide. This study identified 14 QTLs associated with stem rust resistance in different segregating populations. The QTLs were found on chromosomes 3A, 4A, 6A, and 6B, some of which overlapped with previously identified resistance loci. Novel genes or alleles for stem rust resistance may be present on chromosomes 3A and 6B.

Summary: This study investigates the impact of various processing variables during the manufacture and cooking of durum semolina spaghetti on starch digestion and technological quality. Results show that cooking time, particle size distribution of semolina, and addition of a structural enzyme can affect the extent of starch digestion. However, cold storage of cooked pasta has minimal effect on starch digestion and varying extrusion parameters do not impact starch digestion but affect technological quality. The findings suggest the potential to manipulate pasta starch digestion through processing procedures.
