Single-nucleus transcriptomics and phosphoproteomics identify misregulated sperm components in mice carrying a selfish supergene

The paper identifies misregulated sperm components in mice with a selfish supergene using single-nucleus transcriptomics and phosphoproteomics, revealing dysregulated phosphorylation and gene expression related to sperm motility.

Is faster-X adaptation due to large-effect mutations? An empirical test of a new theory

The paper tests a new theory for faster-X adaptation by examining whether large-effect mutations are more positively selected on the X chromosome in three species, but finds no support for this hypothesis.

A single locus carrying modified oogenesis genes underlies the switch to asexuality in Artemia brine shrimp

This study identifies two oogenesis genes on the Z chromosome as potential drivers of asexuality in Artemia brine shrimp by combining single-nucleus RNAseq and whole-genome sequencing.

Causes and consequences of sex-chromosome turnovers in Diptera

The paper identifies 4 new lineages of Diptera that underwent sex-chromosome turnover and analyzes factors contributing to these transitions.

Out with the Old: Contrasting Histone Marks are Associated with Dosage Compensation on the Ancient and New Z of a Moth with Complex Sex Chromosomes

This study investigates dosage compensation mechanisms on sex chromosomes in a moth, revealing distinct patterns on ancestral and neo-sex chromosomes and suggesting new mechanisms evolved in neo-sex chromosomes.

A re-evaluation of Muller's sheltering hypothesis for the evolution of sex chromosome gene content

This paper reevaluates Muller's sheltering hypothesis for sex chromosome evolution, finding that restrictive assumptions in earlier models may have excluded its validity.

Evidence of a Slower-Z effect in Schistosoma japonicum

The paper examines the evolutionary dynamics of diploid and hemizygous Z chromosome regions in Schistosoma japonicum, finding reduced efficacy of selection and relaxed purifying selection in diploid Z regions.

Recurrent sex chromosome turn-over in termites

This study examines the X chromosome evolution in termites, finding that Macrotermes natalensis has a differentiated X chromosome with dosage compensation, while other termite species have younger sex chromosomes, suggesting recurrent sex chromosome turnover.

The Draparnaldia genome: alternative mechanisms for multicellularity and terrestrialization in green plants

This study sequenced the Draparnaldia genome and transcriptomes, revealing expanded gene families linked to multicellularity and terrestrial adaptations, and its ability to synthesize phytohormones used by land plants.
