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

Marwan Elkrewi, Dominik Kopčak, Ariana Macon, Beatriz Viçoso

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.

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

Vincent Kiplangat Bett, Marwan Elkrewi, Ariana Macon, Beatriz Viçoso

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.
