Summary: This study found that the expression of the 1Slx2.3* gene can improve the flour-processing quality of wheat by promoting the accumulation of high-molecular-weight glutenin subunits and low-molecular-weight glutenin subunits, increasing the glutenin:gliadin ratio, and accelerating the formation of protein bodies in the endosperm.

Summary: The formation of allotetraploid wheat through allotetraploidization of A and S genome species had a dominant effect on salinity tolerance. The concentration of Na+ in leaves was not the key factor determining salt sensitivity, while ROS metabolism and flavonoid concentration played important roles in salt sensitivity.

Summary: This study demonstrated the development of 24 specific markers based on the full-length cDNA sequences of Ae. longissima chromosome 6S(l)#3 and the creation of wheat-Ae. longissima 6S(l)#3 introgression stocks, expanding the genetic resources for powdery mildew resistance in wheat. Furthermore, the mapping of Pm6Sl to a specific interval in the long arm of 6S(l)#3 and the identification of two diagnostic markers provide a foundation for fine mapping and cloning the resistance gene.

Summary: Genetic resistance to sharp eyespot in wheat was studied using a recombinant inbred line population. Stable QTL were identified on chromosomes 2B and 7D, as well as novel QTL on 1D, 6D, and 7A, providing potential targets for improving sharp eyespot resistance in wheat breeding programs through marker-assisted selection.

Summary: Wheat sharp eyespot (SES), caused by Rhizoctonia cerealis Van der Hoeven, is a common stem disease of wheat worldwide. In 2014, it caused a severe epidemic in the Willamette Valley of Oregon and has remained a significant wheat disease in the region. A study using a recombinant inbred line (RIL) population found four quantitative trait loci (QTL) associated with SES resistance, which may help in marker-assisted breeding. Genotyping by sequencing revealed low heritability across different environments.

Summary: Aegilops sharonensis, a wild relative of wheat, contains diverse disease and insect resistance genes, which can be used as a valuable gene source for wheat improvement. Molecular cytogenetic marker analysis and disease resistance investigations have identified the potential of A. sharonensis as a new resistance source for wheat breeding.

Summary: In this study, a new wheat leaf rust resistance gene Lr47 was identified, which was introgressed from Aegilops speltoides. The protein encoded by Lr47 contains a nucleotide-binding domain and a leucine-rich repeat domain, and it confers broad-spectrum resistance against leaf rust. Loss-of-function mutations and transgenic complementation experiments confirmed the function of Lr47. Additionally, a diagnostic molecular marker for Lr47 was developed to facilitate breeding selection.

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.

Summary: This study provides the first cytological characterization of the 2N(v)S segment in hexaploid wheat, complete de novo assembly and annotation of the segment. The 2N(v)S segment is associated with resistance to multiple wheat diseases and has a positive impact on wheat grain yield, making it significant in wheat breeding.

Summary: In this study, the wheat-Psathyrostachys huashanica introgression line H83 showed enhanced resistance to sharp eyespot compared to its wheat parent 7182. A major resistance gene, Qse.xn-2BL, was identified and initially mapped to a specific interval on chromosome 2BL. The analysis also revealed the presence of an alien introgression at the distal end of chromosome 2BL in H83.

Summary: Genetic pathogen control is a cost-effective and sustainable alternative to chemical-based methods. In this study, we phenotyped a collection of winter wheat genotypes and identified genetic resistance mechanisms against powdery mildew, a major wheat pathogen. Through genome-wide association study and domain enrichment analysis, we discovered novel candidate genes for disease resistance in wheat.

Summary: The study identifies three candidate genes for the Lr42 leaf rust resistance gene using the BSR-Seq mapping strategy and confirms the function of a nucleotide-binding site leucine-rich repeat gene in conferring resistance. The rare Lr42 resistance allele likely originated from ectopic recombination in Aegilops tauschii. Cloning of Lr42 provides diagnostic markers and its widespread use in crop improvement is well-documented.

Summary: This study investigated the occurrence of eyespot in commercial spring cereal crops and identified the dominant species of Oculimacula responsible for the disease. The research found that the incidence and severity of eyespot disease increased significantly over the study period, with wetter areas having higher disease incidence. The predominance of O. yallundae and the presence of both mating types suggest the possibility of sexual reproduction occurring.

Summary: This study investigated snow mold tolerance in winter wheat by analyzing a doubled haploid population derived from a cross between the Japanese variety PI 173438 and the susceptible variety WA 8137. Six quantitative trait loci (QTL) associated with snow mold tolerance were identified, with one QTL on chromosome 1D being previously unreported. Marker-assisted selection (MAS) testing showed no significant difference among the tested QTL and linked markers in separate populations. These findings highlight the complexity of breeding for snow mold tolerance using molecular markers.

Summary: Soft white club wheat is an important crop in the Pacific Northwest, mainly grown in central Washington but there is also interest in the Palouse region of Washington and Idaho. The 'Cameo' club wheat cultivar has been developed specifically for the Palouse region, with superior agronomic performance, resistance to stripe rust and other stresses, consistent grain quality and tolerance to low falling numbers. It is well suited for increasing the acreage of club wheat in the Palouse region.

Summary: This study aimed to correlate disease intensity in the field with percentage of infected seed and amount of pathogen DNA using a high-throughput PCR method. The results showed that the fluorescent-labeled PCR was more sensitive than the culture-based method or conventional PCR, and disease index was positively correlated with seed infection rate.
