Hybridogenesis as an intermediate step between sexual reproduction and parthenogenesis

The paper traces the evolutionary trajectory from hybridogenesis to parthenogenesis and triploid lineages in stick-insects, showing a stepwise transition driven by genomic changes.

Dynamics of recombination, X inactivation and centromere proteins during stick insect spermatogenesis

This study examines recombination, X inactivation, and centromere protein dynamics during male meiosis in stick insects, revealing unique patterns compared to Drosophila.

Dosage compensation and meiotic sex chromosome inactivation are maintained in the absence of selection

The paper investigates whether dosage compensation and meiotic sex chromosome inactivation persist in parthenogenetic stick insects with relaxed selection, finding both mechanisms are conserved despite the absence of male selection.

Dynamics of X chromosome hyper-expression and inactivation in male tissues during stick insect development

This study examines dosage compensation and meiotic sex chromosome inactivation in stick insects, finding that X chromosome expression is dynamically regulated in male tissues during development.

Recent neo-X and Y sex chromosomes in an ant cricket

The paper identifies young neo-sex chromosomes in ant crickets and estimates their evolutionary origin and recombination suppression events.

Functional monocentricity with holocentric characteristics andchromosome-specific centromeres in a stick insect

The paper analyzes centromere structure and function in stick insects, revealing a functionally monocentric system with holocentric-like features and chromosome-specific centromeres.

Functional insights from the GC-poor genomes of two aphid parasitoids, Aphidius ervi and Lysiphlebus fabarum

The paper presents genome assemblies and analysis of two aphid parasitoid wasps, identifying AT-richness and gene family expansions linked to host interactions and symbiosis.
