Satellite DNA (satDNA) is a major component yet the great unknown of eukaryote genomes
and clearly underrepresented in genome sequencing projects. Here we show the high-…

We investigate regularities and restrictions in chromosome location of ribosomal RNA genes,
analysed by fluorescent in situ hybridization (FISH), and their phenotypic expression …

In some eukaryotes, germline and somatic genomes differ dramatically in their composition.
Here we characterise a major germline–soma dissimilarity caused by a germline-restricted …

For many years, parasitic B chromosomes have been considered genetically inert elements.
Here we show the presence of ten protein-coding genes in the B chromosome of the …

In addition to the standard set of chromosomes (A), about 15% of eukaryote genomes carry
B chromosomes. In most cases, B chromosomes behave as genomic parasites being …

We analyse chromosome location of H3 and H4 histone gene clusters by fluorescence in-situ
hybridization (FISH) in 35 species of Acrididae grasshoppers belonging to seven …

Cactophilic Drosophila species provide a valuable model to study gene–environment
interactions and ecological adaptation. Drosophila buzzatii and Drosophila mojavensis are two …

Background The full catalog of satellite DNA (satDNA) within a same genome constitutes the
satellitome. The Library Hypothesis predicts that satDNA in relative species reflects that in …

B chromosomes are supernumerary genomic elements most likely derived from the standard
(A) chromosomes, whose dispensability has freed their DNA sequences to evolve fast, thus …

We analyze the chromosomal location of 5S rDNA clusters in 29 species of grasshoppers
belonging to the family Acrididae. There was extensive variation among species for the …
