Evolutionary Dynamics of Dosage Compensation and Sex-biased Gene Expression in Morabine Grasshopper Vandiemenella viatica Abstract. Sex chromosome evolution and gene regulation are closely linked but remain understudied in many taxa. Young neo-sex chromosomes offer unique insi

Jayaprasad et al. examined dosage compensation and sex-biased gene expression in Vandiemenella viatica grasshoppers. They show that dosage compensation is regulated at levels of chromosome arms.

Exploring the Satellitome of the Pest Aphid Acyrthosiphon pisum (Hemiptera, Aphididae): Insights Into Genome Organization and Intraspecies Evolution Abstract. Satellite DNAs (satDNAs), ubiquitous sequences in eukaryotic genomes, play a crucial role in genome organization, function, and evolution. The pe

Albuquerque characterized the satellitome of the pea aphid, with results suggesting that satDNAs contribute to genome evolution, biotype divergence, and the “fast-X” effect.

Karyotype evolution and speciation in Orthoptera Abstract. Karyotype evolution might fuel speciation and can thereby contribute to species diversity. To test the hypothesis that speciation and karyotype c

We have recently published a paper that provides insights into the relationship between karyotype changes and speciation, a central question in evolutionary biology.
