Morphometric and genetic analysis as proof of the existence of two sturgeon species in the Guadalquivir river
The DNA of the two specimens captured during the mid-1970s in the Guadalquivir river cross-hybridised with HindIII satellite-DNA sequences of A. naccarii are demonstrated to be autochthonous to the Iberian Peninsula and is not, as was previously believed, endemic to the Adriatic Sea. Expand
Cytogenetic and molecular analysis of the multiple sex chromosome system of Rumex acetosa
The molecular data support an origin of the sex-multiple from a homomorphic chromosome pair rather than from a sex chromosome/autosome translocation. Expand
Reduced Rates of Sequence Evolution of Y-Linked Satellite DNA in Rumex (Polygonaceae)
It is demonstrated that, regardless of the mechanisms that gave rise to these families, satellite-DNA sequences have different evolutionary fates according to their location in different types of chromosomes, supporting the hypothesis that satelliteDNAs in nonrecombining Y chromosomes undergo lower rates of sequence evolution and homogenization than do satellite DNAs in autosomes.

Genomic organization and evolution of the 5S ribosomal DNA in the ancient fish sturgeon.
The results suggest that the evolution of the two parts of the 5S rDNA region cannot be explained exclusively as the outcome of a balance between mutational, homogenizing, and selective forces, and other factors might be superimposed over those forces and thus could to some extent be masking their effects.

Chromosomal location and evolution of a satellite DNA family in seven sturgeon species
The phylogenetic and evolutionary relationships among sturgeon species are discussed on the basis of number and morphology of signal-bearing chromosomes and on the localization of signals. Expand
SatDNA Analyzer: a computing tool for satellite-DNA evolutionary analysis
SatDNA Analyzer generates an output file containing a sequence alignment without shared polymorphisms to be used for further evolutionary analysis by using different phylogenetic softwares. Expand
Variation in the heterochromatin and nucleolar organizing regions of Allium subvillosum L. (Liliaceae)
Two kinds of polymorphisms have been found in a wild population of Allium subvillosum L. (Liliaceae): (i) extra C-bands and supernumerary chromosome segments on three chromosome pairs and (ii) theExpand
Sex Chromosomes in Plants
The molecular phylogeny of the Sparidae (Pisces, Perciformes) based on two satellite DNA families
It is concluded that the Sparidae family is composed by two major lineages: one comprising the species of the genera Sparus, Diplodus, Lithognathus, Boops, Sarpa and Spondyliosoma, and one species of Pagellus (P. erythrinus). Expand
Characterisation of repeated sequences from microdissected B chromosomes of Crepis capillaris
The B chromosome of Crepis capillaris was isolated from the standard chromosomes by microdissection, and the chromosomal DNA amplified using the degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR) confirmed that Bs are evolving separately from A chromosomes at the molecular level.
