Summary: In this study, a dominant resistance gene PmAL11 was identified in wheat and mapped to the Pm5 locus on chromosome 7B. PmAL11, which is most likely a dominant form of Pm5e, provides a valuable resource for genetic study and breeding of resistant wheat cultivars. A new marker AL11-K2488 was developed and confirmed to be applicable for marker-assisted selection of PmAL11 in different wheat backgrounds.

Summary: In this study, the wheat GS1 and GS2 genes were sequenced and analyzed in 15 bread wheat varieties, and significant effects on agronomic and grain quality traits were observed. Molecular markers were developed for genes GS1A, GS2A, and GS2D. Genetic interactions between GS1A and GS2A or GS2D were found to affect thousand-kernel weight and kernels per spike. The masking effect of alleles at one locus on positive alleles at hypostatic GS loci should be considered in gene pyramiding strategies.

Summary: The Atlantic salmon industry in northern Europe is facing increasing losses due to amoebic gill disease (AGD). Genomic selection (GS) can potentially help reduce outbreaks and improve resistance to AGD. Linkage disequilibrium (LD) was evaluated in six Atlantic salmon breeding populations, and the use of genomic information for selection was investigated. The study found that LD decreased with increased physical distance between markers, and long-range LD was observed across all chromosomes. GS models had better performance than the pedigree-based best linear unbiased prediction (PBLUP) model. The use of genomic best linear unbiased prediction (GBLUP) model was recommended for the genetic evaluation of AGD resistance.

Summary: This study aimed to assess the role of four selected single nucleotide polymorphisms (SNPs) in the ERCC5 gene and their association with survival analysis and clinical outcomes in breast cancer. The results showed that rs751402 and rs2094258 were significantly associated with an elevated risk of breast cancer, while rs17655 and rs873601 showed no association. Survival analysis revealed that rs751402 and rs2094258 had longer overall survival periods compared to rs17655 and rs873601. Variations in ERCC5 may contribute to breast cancer development and can be used as a biomarker for clinical outcomes.

Summary: Seed vigor is an important trait in wheat breeding, and this study identified multiple quantitative trait loci (QTLs) associated with various seed vigor traits in a doubled haploid population derived from a cross between Yangmai 16 and Zhongmai 895. The QTLs were located on chromosomes 2B, 3D, 4B, 4D, 5A, 5B, 6A, 6B, 6D, 7A, and 7D, explaining significant portions of the phenotypic variances. The study also developed KASP markers for a QTL cluster on chromosome 4D and validated them in a panel of wheat accessions. These findings provide valuable genetic resources for improving seed vigor in wheat breeding programs.

Summary: Wheat stripe rust, a global cause of yield losses, has overcome resistance in most highly resistant wheat genotypes. The study focuses on testing the effectiveness of Trichoderma asperellum strain T34, a naturally occurring bioagent in Egyptian fields, against the disease. Significant differences were found between T34 and stripe rust, indicating the effectiveness of T34 in resisting stripe rust. A genome-wide association study identified gene models controlling resistance under normal conditions and T34-induced resistance, with only one common gene model found, suggesting two different genetic systems controlling resistance under each condition. Investigation of biological processes sheds light on the genetic control of stripe rust resistance. The study provides valuable insights for future wheat breeding programs.

Summary: Common bunt is a major wheat disease that causes significant damage to grain yield and quality in the USA and Turkey. Although seed treatment with fungicides is an effective control method, it is forbidden in organic and low-income fields, leading to a preference for planting resistant cultivars. The use of fungicides has resulted in limited efforts to breed resistant genotypes, and the genetic diversity for this trait is low in modern wheat germplasm. However, synthetic wheat genotypes have been found to be an effective source of increasing diversity in wheat germplasm.

Summary: Controlling early blight of tomatoes using endophytic bacteria is an eco-friendly and sustainable approach. Three endophytic bacterial isolates, namely Enterobacter cloacae HS-6 (B4), Pseudomonas gessardii HS-5 (B7), and Pseudomonas mediterranea HS-4 (B17), were found to be effective against the growth of pathogenic fungal isolates. The expression of the defense response gene beta-1.3 glucanase increased significantly after inoculation with the efficient biocontrol agent E. cloacae.
