Molecular cytogenetic data on the number and position of 45S ribosomal RNA genes (rDNA;
located in nucleolus organizing regions, NORs) detected by FISH in 330 species of 77 …

In higher eukaryotes, the 5S ribosomal multigene family (5S rDNA) is tandemly organized in
repeat units composed of a coding region (5S rRNA gene) and a nontranscribed spacer …

We present a lobe-based tree representation for modeling trees. The new representation is
based on the observation that the tree's foliage details can be abstracted into canonical …

Fluorescence in situ hybridisation (FISH) and double FISH experiments were carried out to
ascertain the chromosomal distribution pattern of the 45S and 5S ribosomal (r) DNAs in four …

The living fishes span a unique and interesting set of animals because of their vast diversity,
morphology, ecology, genetics and genomics, and higher importance to biology, economy …

Astyanax fasciatus may be characterized as a chromosomally diversified 'species'
presenting distinct cytotypes, each with its specific variants. The sympatric and syntopic …

The heterochromatin composition and loca-tion in the genome of the fish Astyanax
janeiroensis was investigated using Chromomycin A 3 and DAPI fluorochromes and …

Repetitive DNA sequences constitute a great portion of the genome of eukaryotes and are
considered key components to comprehend evolutionary mechanisms and karyotypic …

We report here on the physical mapping of the H1 histone genes (hisDNA) and the 5S
ribosomal DNA (rDNA) in 3 Neotropical fish species of the genus Astyanax (A. altiparanae …

A cytogenetic analysis of the sole Solea senegalensis was carried out using silver staining
for the nucleolus organizer region (Ag-NOR) identification, one-color FISH for chromosomal …
