Summary: This study introgressed the novel wheat powdery mildew and stripe rust resistance genes Pm5V/Yr5V from Dasypyrum villosum and fine mapped them to a narrowed region in 5VS. The results showed that the Pm5V/Yr5V lines have the potential value to facilitate wheat breeding for disease resistance and do not incur a yield penalty in diverse wheat genetic backgrounds.

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 demonstrated that the aberrant transcription of DvGW2 contributed to the increased grain width and thousand-grain weight in wheat-Dasypyrum villosum T6VS·6DL translocation lines. In addition, the 6VS segment may have a direct genetic effect on grain width, driving the increase of thousand-grain weight. Comparative transcriptome analysis identified differentially expressed genes and specifically expressed genes associated with cell proliferation in grains and endosperms, with two candidate genes TaGW2-D1 and DvGW2 being linked to grain weight and yield.

Summary: The study found that wheat-Dasypyrum villosum translocation lines have similar base composition characteristics to common wheat parents, but the genotypes on the translocation chromosomes are more heterozygous. The distribution of SNPs between the translocation lines and Wan7107 is mainly concentrated in the regions of 6AS or 6DS, with some unexpected presence near the telomere of 2BS and other wheat chromosomes. In addition, the translocation lines A303 and B303 have identical genotypes with Wan7107 up to 99.44% and 98.81%, respectively.

Summary: This study identified significant marker trait associations (MTAs) through multi-locus GWAS to improve spike-layer uniformity (SLURTs) and yield in wheat production.279 candidate genes (CGs) were identified, including those associated with wheat spike development, seed development, and grain yield.

Summary: Twenty-two compensating wheat-Dasypyrum villosum translocations carrying the powdery mildew resistance gene PmV were developed using a triple marker selection strategy in a large homozygous ph1bph1b population. These translocations would provide an alternative to the widely used Pm21, reducing the risk of loss of effectiveness due to pathogen changes. The study exemplifies a rapid model for developing wheat-alien compensating translocations that can be utilized in wheat breeding.

Summary: The study investigated the impact of TiO(2)NPs on wheat plants, finding that the addition of biochar can reduce the content of Ti in wheat tissues and decrease the Ti transfer rate. The interactive effect of TiO(2)NPs in combination with biochar amendment on photosynthesis and gas exchange traits was observed to have a positive impact on wheat plants.

Summary: In this study, two recombinant inbred line populations were used to map QTL for spike-related traits in wheat. Forty-two QTLs were identified on different chromosomes, explaining a considerable proportion of the phenotypic variances. New QTL clusters were also detected, providing potential molecular markers for marker-assisted breeding in wheat.

Summary: This study assesses the plasticity of previously unexplored yield sub-components in wheat and tests the effects of nitrogen fertilization at different timings on yield components. The findings suggest that the plasticity of yield components may vary with different sources of environmental variation.

Summary: The prokaryotic communities in the root endosphere have stronger correlations with the yield, quality, and phylogenetic distance of wheat varieties compared to those in the rhizosphere. Managing the root endosphere microbiota, especially the core taxa, is crucial for promoting wheat yield and quality through agronomic practices and crop breeding. This study provides insights into the interactions between wheat variety evolutionary relatedness, root microbiome composition, and their impact on wheat yield and quality.
