Summary: Host plant resistance provided by solid stems has been the most effective means for mitigating wheat stem sawfly (WSS) damage in spring and winter wheat. A new solid stem allele, Qss.msub-3BL.c, was identified in the spring wheat cultivar Conan. It provides effective WSS resistance in spring wheat but has not been tested in winter wheat.

Summary: Hybrid wheat has the potential to yield more than conventional inbred cultivars, but the production cost of hybrid seed needs to be minimized for commercial success. This research identified anther extrusion, pollen 50 date, plant height, and pollination duration as the most important traits for hybrid seed production. These traits varied among genotypes and showed significant differences among years, but consistent performance patterns were observed.

Summary: In this study, two populations of durum x cultivated emmer were evaluated in field conditions across three seasons, leading to the identification of 313 QTLs associated with yield component traits. Among these, 78 were multi-environment QTLs. Cultivated emmer contributed genes that result in increased values for various yield component traits.

Summary: This study used an RNA-seq approach to investigate the transcriptome variation in wheat after extended feeding by wheat curl mites (WCM) for 10 days. The study identified common and specific transcriptomic variations in WCM resistant and susceptible wheat cultivars, as well as differential gene expressions related to defense and stress response, lipid signaling and membrane integrity, and phytohormone pathways potentially contributing to WCM resistance. These findings provide important insights into the defense mechanisms of wheat against WCM after extended feeding.

Summary: The study aims to provide a solution for the registration and fusion of multimodal wheat images, identifying four registration-fusion strategies with different applicability for handling different types of images and local distortions. The suggested methods are limited to the comparisons conducted in this study, and further research is needed to explore the performance of cutting-edge registration methods on the specific case of wheat canopy.

Summary: This study successfully delimited the wheat curl mite resistance gene Cmc4 to a 523 kb region and identified a diagnostic marker haplotype for selecting Cmc4 in breeding programs. It helps in breeding wheat varieties resistant to WCM, reducing its damage to wheat yield and transmission of wheat streak mosaic virus.

Summary: Hexaploid-derived resistance genes exhibit complex inheritance and expression patterns in tetraploid durum wheat. Some genes show dominant effects in hexaploid hybrids, while others exhibit complete dominance in both tetraploid and hexaploid crosses. Multiple gene loci on different chromosomes suppress or promote the expression of resistance genes. Resistance becomes slightly diluted over successive generations, complicating the deployment of these genes in durum breeding programs.

Summary: The study found that the application rate and method of nitrogen fertilizer have certain effects on the water and nitrogen productivity of winter wheat forage; Increasing nitrogen fertilizer rate can increase wheat stem density, height, and herbage yield, but it will have a negative impact on nitrogen productivity; Banded application of nitrogen fertilizer can increase nitrogen accumulation in wheat herbage.

Summary: The rise in atmospheric CO2 levels affects the nutritional integrity and disease resistance of wheat. Wheat cultivars with medium resistance to Fusarium Head Blight (FHB) are more affected by elevated CO2 levels compared to susceptible cultivars. The nutritional content and growth of the medium resistance cultivars show significant differences at elevated CO2 levels. This study highlights the importance of identifying wheat cultivars that can maintain nutritional integrity and FHB resistance under future atmospheric CO2 conditions.

Summary: Wheat streak mosaic virus (WSMV) is a mite-vectored virus that affects wheat production. The resistance source, Wsm1, is carried on a translocation from Thinopyrum intermedium. A shorter recombinant of the translocation, named rec213, was evaluated for its agronomic performance in 10 yield trials. The translocation had no effect on heading date, slightly reduced plant height, and had a positive effect on grain yield. Protein concentration and gluten quality were not affected by the translocation, but there was a slight reduction in protein quality scores. Improved marker assays were developed to facilitate the use of the rec213 Wsm1 trait in breeding programs.

Summary: Meis1 and Meis2 are homeodomain transcription factors that regulate organogenesis by cooperating with Hox proteins. Inactivation of Meis1/2 in the lateral plate mesoderm leads to limb agenesis in mouse embryos, with Meis and Tbx factors co-binding and co-regulating enhancers of Fgf10. Limbs with deleted Meis alleles show skeletal hypoplasia and agenesis of posterior elements due to their early role in establishing limb antero-posterior prepattern.

Summary: Fusarium head blight (FHB) is a concerning disease of wheat, and marker-assisted selection combined with genomic selection is suggested for breeding FHB-resistant varieties. The study used a historical dataset from 2011 to 2021 to predict FHB traits and estimated the heritability for each trait in different environments. Clustering analysis identified two clusters related to Fusarium damaged kernels (FDK) and three clusters related to deoxynivalenol (DON) content. Cross-validation and forward validation showed that selecting environments based on check performance may improve prediction accuracy. This work serves as a model for utilizing public resources in genomic prediction of FHB resistance in wheat breeding programs.

Summary: Interest in spatial omics is growing, but generating highly multiplexed images is challenging due to various factors. A new software called VALIS has been developed to address these challenges by aligning whole slide images (WSI) and generating high-quality, spatially aligned datasets. VALIS provides state-of-the-art accuracy in WSI registration and 3D reconstruction, making it a valuable tool for spatial studies of tumor ecology.

Summary: Yield and quality tests of wheat lines derived from RWG35 show they carry little, or no linkage drag and are the preferred source of Sr47 for stem rust resistance. Breeders who wish to incorporate Sr47 into their cultivars should work exclusively with germplasm derived from RWG35.

Summary: To control the negative impact of winter annual grass species on winter wheat yield, researchers generated winter wheat lines resistant to the herbicide quizalofop p-ethyl (QPE) through mutagenesis. Field trials demonstrated that QPE effectively controlled winter annual grass species with acceptable crop safety in QPE-resistant winter wheat cultivars.

Summary: To ensure food security for the growing global population, it is crucial to increase the yield of staple crops like wheat. This study identified and validated a quantitative trait locus (QTL) on chromosome 6BL that controls spikelet number in wheat. Despite the presence of genetic interactions with other loci, genotypes with more superior alleles consistently showed higher spikelet numbers. This research lays the groundwork for the positional cloning of the genetic variant underlying the QTL, enhancing our understanding of spikelet number determination in wheat.

Summary: Global studies on the climate effects on crop yields provide valuable insights on world food supplies, but lack the resolution to identify local management effects. This study focused on winter wheat yields in eastern Colorado and found that precipitation from April to June was predictive of yields, but temperatures had a larger impact, with extreme maximum temperatures in June having the most detrimental effects.

Summary: Genetic dissection of complex traits in wheat using QTL analysis identified 30 QTL regions associated with yield, end-use quality traits, and agronomic traits. Some of these QTLs were consistent across different chromosomes and showed pleiotropic effects. Three novel QTLs were discovered, along with three major QTLs in colocalization with known genes. Epistasis was also detected. This study provides valuable information for wheat breeding programs through marker-assisted selection.
