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. 🔗 doi.org/10.1093/gbe/evag026 #genome #evolution

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

Albuquerque characterized the satellitome of the pea aphid, with results suggesting that satDNAs contribute to genome evolution, biotype divergence, and the “fast-X” effect. 🔗 doi.org/10.1093/gbe/evaf104 #genome #satellitome

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

Few genetic loci control the green-brown colour polymorphism in the meadow grasshopper Pseudochorthippus parallelus
Abstract. The green-brown polymorphism in Orthoptera is a prominent example of the coexistence of multiple colour variants, especially since this polymorph

We have recently published a paper that provides insights into the relationship between karyotype changes and speciation, a central question in evolutionary biology. doi.org/10.1093/jeb/voaf018 @jevbio.bsky.social

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
