Characterization of different chromatin types in Mytilus galloprovincialis L. after C-banding, fluorochrome and restriction endonuclease treatments
(Nature, 1994-03-01)[Abstract] In this study, we have carried out the cytogenetical characterization of “Mytilus galloprovincialis” L. (2n = 28) using conventional staining and banding techniques such as fluorochromes and restriction endonucleases ... -
Chromosomal markers in three species of the genus Mytilus (Mollusca: Bivalvia)
(Nature, 1995-04-01)[Abstract] The analysis of C-banding, NOR and fluorochrome staining was carried out in three species of European mussel, "Mytilus edulis", "M. galloprovincialis" and "M. trossulus". The results obtained allow us to detect ... -
Chromosome differences between European mussel populations (genus “Mytilus”)
(Taylor & Francis, 1996)[Abstract]: We have analysed different populations of European mussels belonging to genus “Mytilus” in order to clarify the karyotype complements of these three species (“M. edulis”, “M. galloprovincialis” and “M. trossulus”). ... -
Karyotypes and Ag-NORs of the mussels Mytilus californianus and M. trossulus from the Pacific Canadian coast
(Elsevier, 1997-01-01)[Abstract] The karyotypes and the nucleolus organizer regions (NORs) of “M. californianus” and “M. trossulus” from the Pacific coast are reported here for the first time. The karyotypes show seven metacentric and seven ... -
Polyploidy in a Natural Population of Mussel, Mytilus Trossulus
(Canadian Science Publishing, 2000-03)[Abstract] We have analyzed natural polyploidy in a population of “Mytilus trossulus” from Vancouver Island (British Columbia, Canada) by means of cytogenetic techniques. Results obtained are the first reporting on this ... -
DNA content, karyotypes, and chromosomal location of 18S-5.8S-28S ribosomal loci in some species of bivalve molluscs from the Pacific Canadian coast
(Canadian Science Publishing, 2000-12)[Abstract]: The DNA content of 10 species of bivalve molluscs from British Columbia coast was determined by image analysis, and the karyotypes of the horse clam “Tressus capax”, the bent-nose macoma “Macoma nasuta”, and ... -
Telomeric localization of the vertebrate-type hexamer repeat, (TTAGGG) ₙ, in the wedgeshell clam "Donax trunculus" and other marine invertebrate genomes
(American Society for Biochemistry and Molecular Biology, 2002-05-31)[Abstract]: The hexamer repeat sequence (TTAGGG) n, found at the ends of all vertebrate chromosomes, was previously identified as the main building element of one member of aHindIII satellite DNA family characterized in ... -
Molecular and evolutionary analysis of mussel histone genes ("Mytilus" spp.): possible evidence of an "orphon origin" for H1 histone genes
(Springer Nature, 2002-09)[Abstract:] Linker histones are a divergent group of histone proteins with an independent evolutionary history in which, besides somatic subtypes, tissue- and differentiation-specific subtypes are included. In the present ... -
Comparative analysis of different satellite DNAs in four Mytilus species
(Canadian Science Publishing, 2002-10)[Abstract:] We report the characterization of three satellite DNAs in four species of mussel: Mytilus edulis, Mytilus galloprovincialis, Mytilus trossulus, and Mytilus californianus. The monomers of the Apa I satellite ... -
Cytogenetic characterization of “Donax trunculus” (Bivalvia: Donacidae) by means of karyotyping, fluorochrome banding and fluorescent “in situ” hybridization
(Oxford, 2002-11)[Abstract]: The chromosomes of “Donax trunculus” were analysed by means of Giemsa staining, chromomycin A3 (CA3), DAPI and fluorescent “in situ” hybridization (FISH) with an 18S-5.8S-28S rDNA probe. The diploid number is ... -
Cytogenetics of the razor clam "Solen marginatus" (Mollusca: Bivalvia: Solenidae)
(Karger, 2003)[Abstract:] The razor clam Solen marginatus has a diploid chromosome number of 38. The karyotype consists of one metacentric/submetacentric, three submetacentric/metacentric, five submetacentric, one submetacentric/subtelocentric, ... -
Molecular evolutionary characterization of the mussel "Mytilus" histone multigene family: first record of a tandemly repeated unit of five histone genes containing an H1 subtype with orphon features
(Springer Nature, 2004-02)[Abstract] The present work represents the first characterization of a clustered histone repetitive unit containing an H1 gene in a bivalve mollusk. To complete the knowledge on the evolutionary history of the histone ... -
Birth-and-death evolution with strong purifying selection in the histone H1 multigene family and the origin of "orphon" H1 genes
(Oxford University Press, 2004-10)[Abstract:] Histones are small basic nuclear proteins with critical structural and functional roles in eukaryotic genomes. The H1 multigene family constitutes a very interesting histone class gathering the greatest number ... -
Origin and evolution of "Mytilus" mussel satellite DNAs
(Canadian Science Publishing, 2005-04)[Abstract] A phylogenetic reconstruction based on the amplification of 3 satellite DNAs (stDNAs) was carried out in 1 crustacean species and 15 bivalve species of the subclass Pteriomorphia (10, subfamily Mytilinae; 1, ... -
