Identification of a viral gene essential for the genome replication of a domesticated endogenous virus in ichneumonid parasitoid wasps

This study identifies a viral gene, U16, essential for genome replication of an ichnovirus in ichneumonid wasps, showing its role in DNA amplification and virion production.

An effector deletion leads to the breakdown of partial grapevine resistance to downy mildew

The paper identifies an effector deletion in Plasmopara viticola that leads to the breakdown of Rpv3.1-mediated grapevine resistance.

A quarter-million-year-old polymorphism drives reproductive mode variation in the pea aphid

The paper identifies an X-linked 840-kb genomic region responsible for reproductive mode variation in pea aphids, showing divergence dating to ~0.25 million years ago.

Host-plant adaptation as a driver of incipient speciation in the fall armyworm (Spodoptera frugiperda)

The paper examines genetic differentiation between corn and rice strains of fall armyworm to assess host-plant adaptation's role in incipient speciation.

Masculinization of the X-chromosome in aphid soma and gonads

The paper examines X-chromosome masculinization in aphid tissues, finding male-biased genes are more frequent on the X and duplicated X genes show higher male bias, supporting sexual conflict resolution through gene duplication.

Genomic balancing selection is key to the invasive success of the fall armyworm

This study shows genomic balancing selection restored heterozygosity in the Fall armyworm, enabling its global invasion success despite population bottlenecks.

Adaptation by copy number variation increases insecticide resistance in fall armyworms

This study investigates whether copy number variation in detoxification genes contributes to insecticide resistance in fall armyworms, finding significant allelic differentiation in resistant populations.

Disentangling The Causes For Faster-X Evolution In Aphids

This study investigates faster-X evolution in aphids by analyzing gene expression, substitution rates, and polymorphism data to determine the role of selection and drift.
