Systematic analysis and evolution of 5S ribosomal DNA in metazoans
(Springer Nature, 2013-07-10)
[Abstract] Several studies on 5S ribosomal DNA (5S rDNA) have been focused on a subset of the following features in mostly one organism: number of copies, pseudogenes, secondary structure, promoter and terminator ...
Accessing transcriptomic data for ecologically important genes in the goose barnacle ("Pollicipes pollicipes"), with particular focus on cement proteins
(Elsevier, 2014-03-04)
[Abstract] In this study 4310 expressed sequence tags (ESTs) were used to identify potentially useful transcripts for future studies in the gooseneck barnacle Pollicipes pollicipes (Gmelin, 1789). 119 ESTs were obtained ...
Population genetic analysis of "Ensis directus" unveils high genetic variation in the introduced range and reveals a new species from the NW Atlantic
(Springer Nature, 2012-07-31)
[Abstract] We report current genetic variation of populations of the razor shell Ensis directus (Conrad 1843) (Mollusca: Bivalvia: Pharidae) in native (North American) and introduced (European) ranges using nuclear and ...
The linked units of 5S rDNA and U1 snDNA of razor shells (Mollusca: Bivalvia: Pharidae)
(Nature, 2011-08)
[Abstract] The linkage between 5S ribosomal DNA and other multigene families has been detected in many eukaryote lineages, but whether it provides any selective advantage remains unclear. In this work, we report the ...
The 5S rDNA gene family in mollusks: characterization of transcriptional regulatory regions, prediction of secondary structures, and long-term evolution, with special attention to Mytilidae mussels
(Oxford University Press, 2011-07-01)
[Abstract] Several reports on the characterization of 5S ribosomal DNA (5S rDNA) in various animal groups have been published to date, but there is a lack of studies analyzing this gene family in a much broader context. ...
Analysis of ITS1 and ITS2 sequences in "Ensis" razor shells: suitability as molecular markers at the population and species levels, and evolution of these ribosomal DNA spacers
(Canadian Science Publishing, 2010-01)
[Abstract] Internal transcribed spacer 1 and 2 (ITS1 and ITS2) sequences were analysed in Ensis razor shells (Mollusca: Bivalvia: Pharidae). We aimed to (1) test ITS1 and ITS2 as molecular markers at the population level ...
Cytogenetic characterisation of the razor shells "Ensis directus" (Conrad, 1843) and "E. minor" (Chenu, 1843) (Mollusca: Bivalvia)
(Springer Nature, 2012-04-26)
[Abstract] The European razor shell Ensis minor (Chenu 1843) and the American E. directus (Conrad 1843) have a diploid chromosome number of 38 and remarkable differences in their karyotypes: E. minor has four metacentric, ...
Molecular organization and phylogenetic analysis of 5S rDNA in crustaceans of the genus "Pollicipes" reveal birth-and-death evolution and strong purifying selection
(BioMed Central, 2011-10-17)
[Abstract]
Background: The 5S ribosomal DNA (5S rDNA) is organized in tandem arrays with repeat units that consist of a transcribing region (5S) and a variable nontranscribed spacer (NTS), in higher eukaryotes. Until ...
Genetic heterogeneity in natural beds of the razor clam "Ensis siliqua" revealed by microsatellites
(Cambridge University Press, 2011-06-09)
[Abstract] The aim of this study was to analyse the genetic diversity and population structure in the razor clam Ensis siliqua along the European Atlantic coast taking into account their recent history of exploitation and ...
Isolation and characterization of 21 polymorphic microsatellite loci for the rockpool shrimp Palaemon elegans using Illumina MiSeq sequencing
(Springer Nature, 2018-11-21)
[Abstract] The rockpool shrimp Palaemon elegans is considered an important crustacean species within the European coastline fauna. This species is experiencing an ongoing geographical expansion beyond its native distribution ...
