Background 45S rDNA sites are the most widely documented chromosomal regions in
eukaryotes. The analysis of the distribution of these sites along the chromosome in several …

Chromosomal data have been underutilized in phylogenetic investigations despite the
obvious potential that cytogenetic studies have to reveal both structural and functional …

Tandem repeats can occupy a large portion of plant genomes and can either cause or result
from chromosomal rearrangements, which are important drivers of dysploidy-mediated …

Background Geographical isolation has generated a distinct difference between Atlantic
salmon of European and North American Atlantic origin. The European Atlantic salmon …

Polydnaviruses, obligatorily associated with endoparasitoid wasps, are unique in that their
segmented genome is composed of multiple double-stranded DNA circles. We present here …

Turtle karyotypes are highly conserved compared to other vertebrates; yet, variation in
diploid number (2n= 26-68) reflects profound genomic reorganization, which correlates with …

Simple Summary The class Insecta constitutes the largest group of terrestrial animals, with
more than a million described species. As in all other animals, insect genomes contain …

This study compares results on reconstructing the ancestral state of characters and ancestral
areas of distribution in Cornaceae to gain insights into the impact of using different analytical …

East Africa is a hotspot of biodiversity of many orthopteran taxa, including bushcrickets.
Gonatoxia Karsch, 1889 species are fully alate Phaneropterinae, which are perfectly …

Introduction Tandem repeats (TRs) occur abundantly in plant genomes. They play essential
roles that affect genome organization and evolution by inducing or generating chromosomal …
