Different behaviour of C-banded peri-centromeric heterochromatin between sex chromosomes and autosomes in Polyphagan beetles

Autor: Anne-Marie Dutrillaux, Bernard Dutrillaux

Publikováno v: Comparative Cytogenetics, Vol 13, Iss 2, Pp 179-192 (2019)

Heterochromatin variation was studied after C-banding of male karyotypes with a XY sex formula from 224 species belonging to most of the main families of Coleoptera. The karyotypes were classified in relation with the ratio heterochromatin/euchromati

Telomeric heterochromatin and meiotic recombination in three species of Coleoptera (Dorcadion olympicum Ganglebauer, Stephanorrhina princeps Oberthür and Macraspis tristis Laporte)

Autor: Anne-Marie Dutrillaux, Bernard Dutrillaux

Publikováno v: Caryologia, Vol 72, Iss 2 (2019)

Centromeres are generally embedded in heterochromatin, which is assumed to have a negative impact on meiotic recombination in adjacent regions, a condition required for the correct segregation of chromosomes at anaphase I. At difference, telomeric an

Loss of Y chromosome may be a synapomorphy of the tribe Lepturini (Coleoptera: Cerambycidae: Lepturinae)

Autor: Anne-Marie DUTRILLAUX, Bernard DUTRILLAUX

Publikováno v: European Journal of Entomology, Vol 115, Iss 1, Pp 45-52 (2018)

Phylogeny and higher classification of the cerambycid subfamily Lepturinae remain controversial. Here we report the results of a cytogenetic study of 18 species currently classified in Lepturini and 12 species in other tribes of Lepturinae (1 in Oxym

Unbalanced sex ratio and triploidy in the genus Cyclocephala (Coleoptera: Scarabaeoidea: Dynastidae) in the Lesser Antilles: An example of parthenogenesis on islands?

Autor: Bernard DUTRILLAUX, Dominique PLUOT-SIGWALT, Anne-Marie DUTRILLAUX

Publikováno v: European Journal of Entomology, Vol 111, Iss 3, Pp 313-319 (2014)

Sex ratio and chromosomes studies were performed on six of the seven species of genus Cyclocephala present in the Lesser Antilles. Most sex ratios based on light trapping are skewed, with a frequent, but not exclusive, strong excess of females. These

Genome assembly of 3 Amazonian Morpho butterfly species reveals Z-chromosome rearrangements between closely related species living in sympatry

Autor: Héloïse Bastide, Manuela López-Villavicencio, David Ogereau, Joanna Lledo, Anne-Marie Dutrillaux, Vincent Debat, Violaine Llaurens

Publikováno v: GigaScience. 12

The genomic processes enabling speciation and species coexistence in sympatry are still largely unknown. Here we describe the whole-genome sequencing and assembly of 3 closely related species from the butterfly genus Morpho: Morpho achilles (Linnaeus

Improved basic cytogenetics challenges holocentricity of butterfly chromosomes

Autor: Bernard Dutrillaux, Anne-Marie Dutrillaux, Mélanie McClure, Marc Gèze, Marianne Elias, Bertrand Bed’hom

Publikováno v: Cytogenetic And Genome Research (1424-8581) (S. Karger AG), 2023-02, Vol. 162, N. 5, P. 262-272

Mitotic chromosomes of butterflies, which look like dots or short filaments in most published data, are generally considered to lack localised centromeres and thus to be holokinetic. This particularity, observed in a number of other invertebrates, is

Why Are X Autosome Rearrangements so Frequent in Beetles? A Study of 50 Cases

Autor: Bernard Dutrillaux, Anne-Marie Dutrillaux

Publikováno v: Genes; Volume 14; Issue 1; Pages: 150

Amongst the 460 karyotypes of Polyphagan Coleoptera that we studied, 50 (10.8%) were carriers of an X autosome rearrangement. In addition to mitotic metaphase analysis, the correct diagnosis was performed on meiotic cells, principally at the pachyten

A dual molecular and cytogenetic study was performed with the aim to improve the controversial systematic classification of some species of Lamiinae (Coleoptera: Cerambycidae). The karyotypes of species belonging to genera Morimus, Herophila, Dorcadi

Parthenogenesis, the development of unfertilized eggs resulting in the exclusive production of female offspring, is rare in animals relative to sexual reproduction and is mainly reported in invertebrates. It has been hypothesized that polyploidy, hyb
