The evolution of reproductive systems and sex-determining mechanisms within rumex (polygonaceae) inferred from nuclear and chloroplastidial sequence data.
TLDR
The results support the contention that sex determination based on the balance between the number of X chromosomes and theNumber of autosomes (X/A balance) has evolved secondarily from male-determining Y mechanisms and that multiple sex-chromosome systems were derived twice from an XX/XY system. Expand
The molecular diagnosis of Marteilia refringens and differentiation between Marteilia strains infecting oysters and mussels based on the rDNA IGS sequence
TLDR
Molecular characterization of this rDNA intergene spacer indicates that the Marteilia parasites which infect oysters and mussels are two different strains of the same species. Expand
Evolution of ancient satellite DNAs in sturgeon genomes.
TLDR
It is found that, in contrast to the situation in most other living beings, a high degree of preservation, a slow sequence change rate and slowed concerted evolution, appears to be a general rule for sturgeon satellite DNAs. Expand
The molecular phylogeny of oysters based on a satellite DNA related to transposons.
TLDR
The homology of oyster HindIII satellite DNA with satellite DNAs from other bivalves and its relation to a part of a mobile element suggest the existence of an ancient transposable element as a generating unit of satellite DNA in bivalve molluscs. Expand
Morphometric and genetic analysis as proof of the existence of two sturgeon species in the Guadalquivir river
TLDR
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
An Expressed Sequence Tag (EST)-enriched genetic map of turbot (Scophthalmus maximus): a useful framework for comparative genomics across model and farmed teleosts
TLDR
A consensus gene-enriched high-resolution genetic map of the turbot was constructed using 463 SNP and microsatellite markers in nine reference families and showed large synteny conservation against model teleost genomes. Expand
Identification of Marteilia refringens infecting the razor clam Solen marginatus by PCR and in situ hybridization.
TLDR
In situ hybridization analysis showed tissue distribution and presence of different developmental stages of the parasite in the digestive diverticula epithelium, which suggested a true parasitism in these individuals, the first report of the occurrence of M. refringens in the razor clam S. marginatus in the south Atlantic. Expand
Pseudomonas baetica sp. nov., a fish pathogen isolated from wedge sole, Dicologlossa cuneata (Moreau).
TLDR
Five Gram-negative bacterial isolates recovered from an outbreak that occurred in March 2006 in Huelva, Spain, affecting adult diseased cultured wedge sole, were characterized phenotypically and genotypically in order to clarify their taxonomic position. Expand
Angiotensin-converting enzyme and p22(phox) polymorphisms and the risk of coronary heart disease in a low-risk Spanish population.
TLDR
Among subjects of a Mediterranean population with low risk for CHD, the presence of DD ACE genotype could be a risk factor for myocardial infarction, and the linkage disequilibrium between two nucleotide positions of the ACE gene and the polymorphism for an Alu insertion is confirmed. Expand
Characterization of ISR region and development of a PCR assay for rapid detection of the fish pathogen Tenacibaculum soleae.
TLDR
The PCR assay proved to be more sensitive than agar cultivation for the detection of T. soleae from naturally diseased fish, offering a useful tool for diagnosis and for understanding the epidemiology of this pathogen. Expand
