Transposable element disruption of a second thyroglobulin-like gene confers Vip3Aa resistance in Helicoverpa armigera

This study identifies a second thyroglobulin-like gene, HaVipR2, as a novel mediator of Vip3Aa resistance in *Helicoverpa armigera*, demonstrating that a ~16 kb transposable element insertion disrupts this gene to confer high-level resistance and highlighting the critical role of long-read sequencing in detecting such adaptive mutations.

Over-representation of sperm-associated deleterious mutations across wild and ex situ cheetah (Acinonyx jubatus) populations

This study analyzes whole-genome data from wild and captive cheetahs to reveal that deleterious mutations are significantly enriched in sperm-related genes, likely contributing to poor sperm quality, while confirming that captive breeding programs have successfully maintained genetic diversity comparable to wild populations.

Systemic mutagen exposures reported by normal kidney cell genomes

By analyzing single-molecule duplex sequencing data from normal kidney and blood samples across 10 countries, researchers discovered that kidney proximal tubule cells accumulate high levels of somatic mutations from both known exogenous carcinogens, such as aristolochic acids, and unidentified systemic mutagens, revealing these cells as highly sensitive sentinels for detecting widespread environmental exposures.

Comparative genomics of Cadophora luteo-olivacea reveals a divergent lineage, conserved functional repertoires, and strain-level variation in pathogenicity

This study reveals that while most *Cadophora luteo-olivacea* strains share a conserved genomic framework and plant-colonizing capacity, they exhibit significant strain-level variation in pathogenicity and host-specific responses, alongside the identification of a highly divergent lineage (CBS 266.93) that warrants taxonomic reassessment.

Benchmarking SNP-Calling Accuracy Against Known Citrus Pedigrees Reveals Pangenome Advantages Over Linear References

This study demonstrates that while graph-based pangenomes and linear references yield similar Mendelian inheritance error rates, pangenome approaches significantly improve the reconstruction of parental haplotype blocks in citrus breeding, offering a superior framework for benchmarking SNP-calling accuracy in non-model systems by mitigating reference bias in diverged genomic regions.

Endogenous mutational mechanisms and metabolic context shape endometrial cancer

This study analyzes deep whole-genome sequencing data from 440 endometrial tumors to reveal how endogenous mutational mechanisms, retrotransposition activity, and host metabolic factors like BMI distinctively shape the genomic architecture and evolutionary trajectories of molecular subtypes, offering a mutagenesis-centric framework for improved risk stratification and therapeutic strategies.
