Recurring X-autosome fusions in Aeshna dragonflies break 300 million years of karyotypic stasis

The paper identifies recurrent X-autosome fusions in Aeshna dragonflies, breaking 300 million years of karyotypic stasis and revealing patterns of neo-sex chromosome formation.

Coexisting Y haplotypes reveal cyclic sex chromosome differentiation around a shared sex-determining region

The paper investigates sex chromosome evolution in frogs by analyzing coexisting Y haplotypes, revealing cyclic differentiation dynamics rather than unidirectional degeneration.

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.

First Genomic Insights into an Aeshnidae Dragonfly: Unveiling the Genome of a Holarctic Species, Aeshna juncea

This paper presents the first assembled genome of Aeshna juncea, revealing transposon-driven genome size variation and population bottlenecks in Arctic populations.

Evidence for the major role of PH4EFB in the prolyl 4-hydroxylation of Drosophila collagen IV

This study identifies PH4EFB as the primary prolyl 4-hydroxylase for collagen IV in Drosophila through bioinformatic, transcriptomic, and biochemical analyses.

Early sex-chromosome evolution in the diploid dioecious plant Mercurialis annua

This study identifies the sex chromosome in Mercurialis annua using genomic and transcriptomic data, revealing suppressed recombination and X/Y sequence divergence without extensive Y-chromosome degeneration.
