Evolutionary dynamics of rDNA clusters on chromosomes of moths and butterflies (Lepidoptera)
TLDR
E ectopic recombination is proposed, i.e., homologous recombination between repetitive sequences of non-homologous chromosomes, as a primary motive force in rDNA repatterning.
Neo-sex chromosomes and adaptive potential in tortricid pests
TLDR
It is suggested that this Z–autosome fusion brought two major genes conferring insecticide resistance and clusters of genes involved in detoxification of plant secondary metabolites under sex-linked inheritance to the tortricid moths and thus contributed to their radiation and subsequent speciation.
A chromosome-level genome assembly of Cydia pomonella provides insights into chemical ecology and insecticide resistance
TLDR
The high-quality genome assembly of C. pomonella informs the genetic basis of its invasiveness, suggesting the codling moth has distinctive capabilities and adaptive potential that may explain its worldwide expansion.
Codling moth cytogenetics: karyotype, chromosomal location of rDNA, and molecular differentiation of sex chromosomes.
TLDR
The demonstrated ways of W chromosome identification will facilitate the development of genetic sexing strains desirable for pest control using the sterile insect technique.
Linkage map of the peppered moth, Biston betularia (Lepidoptera, Geometridae): a model of industrial melanism
TLDR
A linkage map for the peppered moth, the classical ecological genetics model of industrial melanism, aimed both at localizing the network of loci controlling melanism and making inferences about chromosome dynamics, highlights the unusual evolutionary stability of lepidopteran autosomes.
Neo-sex Chromosomes in the Monarch Butterfly, Danaus plexippus
TLDR
The discovery of a neo-Z and the provisional assignment of chromosome linkage for >90% of D. plexippus genes lays the foundation for novel insights concerning sex chromosome evolution in this female-heterogametic model species for functional and evolutionary genomics.
Sex Chromosome Pairing and Extensive NOR Polymorphism in Wadicosa fidelis (Araneae: Lycosidae)
TLDR
The obtained data indicate the rapid spread of NORs in the karyotype of W. fidelis, which was presumably caused by ectopic recombinations and subsequent hybridisations of individuals with different NOR genotypes that produced heterozygotes.
Probing the W chromosome of the codling moth, Cydia pomonella, with sequences from microdissected sex chromatin
TLDR
The results show that the approach is feasible and that the W-chromosome composition of C. pomonella is not principally different from that of Bombyx mori or from those of Y chromosomes of several species with an XY sex-determining mechanism.
Dynamic karyotype evolution and unique sex determination systems in Leptidea wood white butterflies
TLDR
A curious sex determination system with 3–4 W and 3-4 Z chromosomes is revealed, which is unique in the Lepidoptera and which could also have played a role in the speciation process of the three Leptidea species.
Divergent location of ribosomal genes in chromosomes of fish thorny-headed worms, Pomphorhynchus laevis and Pomphorhynchus tereticollis (Acanthocephala)
TLDR
Fluorescence in situ hybridization with 18S rDNA probe identified two clusters of rDNA in each species, but revealed a remarkable difference in their location on chromosomes, which means that each Pomphorhynchus NOR generates a nucleolus, but the resulting nucleoli have a strong tendency to associate in a large body.
