The paper presents 25 new microsporidian genomes, revealing extreme pangenome diversity and novel tetraploid structures in some species.

Across 325 Darwin Tree of Life genomes, satellite-array and transposon-cluster centromeres are phylogenetically scattered, fitting a model of repeated interconversion; satellites share higher-order repeat structure but not sequence.

The paper quantifies the faster-X effect in globular springtails by analyzing whole-genome resequencing and RNA-Seq data, finding stronger purifying and positive selection on X-linked genes.

From 338 beetle genomes, eight ancestral linkage groups were inferred; rearrangement rates vary widely, peaking in major radiations, and the X chromosome dates to Holometabola's ancestor.

This study tracks hybrid fitness in Tetranychus urticae over 50 generations, showing initial incompatibilities resolve and hybrids gain adaptive potential in novel environments.

The paper reconstructs ancestral linkage groups in 340 dipteran genomes to study chromosome evolution, finding conserved groups in Nematoceran lineages and chromosomal fissions in Brachycera.

The paper investigates chromosomal evolution in sedges and rushes, finding evidence of polycentromeres and their impact on genome rearrangement rates and segregation patterns.

This study generates chromosome-scale genome assemblies of germline restricted chromosomes (GRCs) in fungus gnats and finds they evolve dynamically with gene-rich content under strong purifying selection.

The paper presents 40 new microsporidian genomes, revealing evidence of sexual reproduction and autopolyploidy, with tetraploid genomes organized into diploid compartments.

The paper estimates ploidy levels across Microsporidia using k-mer analyses and finds polyploidy is widespread and dynamic.

The paper confirms paternal genome elimination in Allacma fusca by showing sperm carry only one parental haplotype, suggesting maternal inheritance, and introduces a genomic method to detect germline-soma differences.

The paper re-analyzes genomic data to define clades of monomorphic Trypanozoon species and identifies lineage-specific variation, challenging traditional classifications and suggesting evolutionary relationships.

The paper systematically analyzes genomic features of 26 parthenogenetic animals and finds that no feature is consistently replicated across transitions to asexuality, suggesting lineage-specific patterns.

GenomeScope 2.0 and Smudgeplots provide reference-free tools to profile polyploid genomes by analyzing k-mer frequencies to estimate genome size, ploidy, and structure.
