Polyommatine Blue Butterflies Reveal Unexpected Integrity of the W Sex Chromosome Amid Extensive Chromosomal Fragmentation Linked to Telomere Restoration Open
Chromosomal rearrangements act as barriers to gene flow and can thus promote speciation. In moths and butterflies (Lepidoptera), which possess holocentric chromosomes facilitating karyotype changes, chromosome fusions are more common than …

A W chromosome-derived feminizing piRNA in pyralid moths demonstrates convergent evolution for primary sex determination signals in Lepidoptera Open
Background The primary signals of sex determination in insects are diverse and evolve erratically. This also appears to be the case with moths and butterflies. In the silkworm Bombyx mori , female development is triggered by a W-linked Fem…

Polyommatine blue butterflies reveal unexpected integrity of the W sex chromosome amid extensive chromosome fragmentation Open
Chromosomal rearrangements are crucial in speciation, acting as barriers to gene flow. Holocentric chromosomes, such as those in Lepidoptera, can facilitate karyotype changes. Despite chromosome fusions being more common, speciation events…

Ghost W chromosomes and unique genome architecture in ghost moths of the family Hepialidae Open
The classical model of sex chromosome evolution has been recently challenged in moths and butterflies (Lepidoptera). According to the current hypothesis, the adoption of a supernumerary chromosome may have driven the transition from the Z0…

The Role of Repetitive Sequences in Repatterning of Major Ribosomal DNA Clusters in Lepidoptera Open
Genes for major ribosomal RNAs (rDNA) are present in multiple copies mainly organized in tandem arrays. The number and position of rDNA loci can change dynamically and their repatterning is presumably driven by other repetitive sequences. …

The role of repetitive DNA in re-patterning of major rDNA clusters in Lepidoptera Open
Genes for major ribosomal RNAs (rDNA) are present in multiple copies organized in tandem arrays. Number and position of rDNA loci can change dynamically and their re-patterning is presumably driven by repetitive sequences. We explored a pe…

Absence of W Chromosome in Psychidae Moths and Implications for the Theory of Sex Chromosome Evolution in Lepidoptera Open
Moths and butterflies (Lepidoptera) are the largest group with heterogametic females. Although the ancestral sex chromosome system is probably Z0/ZZ, most lepidopteran species have the W chromosome. When and how the W chromosome arose rema…

Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea Open
Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. In vertebrates, sex chromosome-autosome fusions resulting in neo-sex chromosomes occur frequently in male heterogametic t…
