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 ...
Long-term evolution of 5S ribosomal DNA seems to be driven by birth-and-death processes and selection in "Ensis" razor shells (Mollusca: Bivalvia)
(Springer Nature, 2009-10)
[Abstract] A study of nucleotide sequence variation of 5S ribosomal DNA from six Ensis species revealed that several 5S ribosomal DNA variants, based on differences in their nontranscribed spacers (NTS), occur in Ensis ...
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. ...
Common evolutionary origin and birth-and-death process in the replication-independent histone H1 isoforms from vertebrate and invertebrate genomes
(Springer Nature, 2005-09)
[Abstract]The H1 histone multigene family shows the greatest diversity of isoforms among the five histone gene families, including replication-dependent (RD) and replication-independent (RI) genes, according to their ...
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 ...
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 ...
