Expression of 5S rDNA in the oocytes of water frogs [PDF]
BMC Research Notes, 2009 Background We report the expression pattern of 5S rDNA in the eggs of water frogs Rana lessonae, Rana ridibunda and Rana esculenta using the quantitative real-time PCR. This kind of research had never been performed before.

Research Progress on 35S rDNA and 5S rDNA in Sugarcane: Challenges and Prospects. [PDF]
Int J Mol ScirDNA is abundant in various organisms, typically expressed as conserved tandem repeats. It plays a crucial role in ribosome synthesis, gene transcription, and expression, and it affects the occurrence of diseases in both animals and plants, aging ...

Heterochromatic siRNAs and DDM1 independently silence aberrant 5S rDNA transcripts in Arabidopsis. [PDF]
PLoS ONE, 2009 5S ribosomal RNA gene repeats are arranged in heterochromatic arrays (5S rDNA) situated near the centromeres of Arabidopsis chromosomes. The chromatin remodeling factor DDM1 is known to maintain 5S rDNA methylation patterns while silencing transcription ...

Molecular organization of 5S rDNA in fishes of the genusBrycon [PDF]
Genome, 2001 There are few reports on the genomic organization of 5S rDNA in fish species. To characterize the 5S rDNA nucleotide sequence and chromosomal localization in the Neotropical fishes of the genus Brycon, 5S rDNA copies from seven species were generated by ...

Molecular organization and phylogenetic analysis of 5S rDNA in crustaceans of the genus
BMC Evolutionary Biology, 2011 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 recently the 5S rDNA was thought to be subject to

Structure of 5S rDNA sequence of the gibel carp (Carassius gibelio) with 2n=100 chromosomes
Frontiers in Marine Science, 2015 In vertebrate, the 5S ribosomal DNA (rDNA) consists of a conserved coding (transcriptional) unit of 120 bp (5S), which is separated from the next unit by a nontranscribed spacer (NTS). The coding sequence and the NTS together form a repeat unit which can

A Pol V-mediated silencing, independent of RNA-directed DNA methylation, applies to 5S rDNA. [PDF]
PLoS Genetics, 2009 The plant-specific RNA polymerases Pol IV and Pol V are essential to RNA-directed DNA methylation (RdDM), which also requires activities from RDR2 (RNA-Dependent RNA Polymerase 2), DCL3 (Dicer-Like 3), AGO4 (Argonaute), and DRM2 (Domains Rearranged ...

Nucleolar association and transcriptional inhibition through 5S rDNA in mammals. [PDF]
PLoS Genetics, 2012 Changes in the spatial positioning of genes within the mammalian nucleus have been associated with transcriptional differences and thus have been hypothesized as a mode of regulation.

Higher-order organisation of extremely amplified, potentially functional and massively methylated 5S rDNA in European pikes (Esox sp.) [PDF]
BMC Genomics, 2017 Background Pikes represent an important genus (Esox) harbouring a pre-duplication karyotype (2n = 2x = 50) of economically important salmonid pseudopolyploids.
