Evidence that in higher plants the 25S and 18S rRNA genes are not interspersed with genes for 5S rRNA

Chromosoma, 1978
DNA samples from various higher plants (Phaseolus aureus, Glycine max, Matthiola incana, Brassica pekinensis, Cucumis melo) were centrifuged in actinomycin-caesium chloride gradients and the genes coding for the ribosomal RNAs were detected by hybridisation with tritium labelled 5S and 25S+18S rRNA, respectively.

Novelty in Phylogeny of Gastrotricha: Evidence from 18S rRNA Gene

Molecular Phylogenetics and Evolution, 1999
Gastrotricha form a phylum which is crucial for defining the origin of pseudocoelomates, in that they share a number of characters with Rotifera and Nematoda but also with acoelomates, and even the evolutionary relationships within the phylum are anything but defined.

Localization of the 18S, 5.8S and 28S rRNA genes and the 5S rRNA genes in the babirusa and the white-lipped peccary

Cytogenetics and Cell Genetics, 2008
The locations of the genes encoding 18S, 5.8S and 28S rRNA and 5S rRNA were studied in two relatives of the domestic pig, the babirusa (Babyrousa babyrussa) and the white-lipped peccary (Tayassu pecari). In the babirusa, the 18S, 5.8S and 28S rDNA is located on chromosomes 6, 8 and 10.

Geographical variation in 18S rRNA gene sequence of Cryptosporidium parvum

International Journal for Parasitology, 1994
Using 18S rRNA as a probe, an EcoR1 fragment containing 1507 nt of 18S rRNA from C. parvum was identified, cloned and sequenced. Comparison of this sequence with the partial sequence of the small subunit rRNA of Cryptosporidium published by Johnson, Fielke, Lumb & Baverstock (International Journal for Parasitology 20: 141-147, 1990) and 1516 bp of the ...

ITS-2 and 18S rRNA gene phylogeny of Aplysinidae (Verongida, Demospongiae)

Journal of Molecular Evolution, 2005
18S ribosomal DNA and internal transcribed spacer 2 (ITS-2) full-length sequences, each of which was sequenced three times, were used to construct phylogenetic trees with alignments based on secondary structures, in order to elucidate genealogical relationships within the Aplysinidae (Verongida).

Higher Taxa of Basidiomycetes: An 18S Rrna Gene Perspective

Mycologia, 1993
ABSTRACTIn order to identify monophyletic groups and evaluate competing class level systems of classification, we sequenced the 18S rRNA gene from nine basidiomycetes.

A Molecular Phylogenetic Framework for the Phylum Ctenophora Using 18S rRNA Genes

Molecular Phylogenetics and Evolution, 2001
This paper presents the first molecular phylogenetic analysis of the phylum Ctenophora, by use of 18S ribosomal RNA sequences from most of the major taxa. The ctenophores form a distinct monophyletic group that, based on this gene phylogeny, is most closely related to the cnidarians. Our results suggest that the ancestral ctenophore was tentaculate and

Phylogenetics of Sarcocystis fusiformis isolates based on 18S rRNA and cox 1 genes

Microbial Pathogenesis, 2021
Sarcocystosis is a significant meat borne coccidian disease with immense zoonotic potential. Sarcocystis fusiformis is the most prevalent Sarcocystis spp. affecting buffaloes across the globe. Most of the molecular characterization works on S. fusiformis are from Egypt and there is no record of such work from India. In the present study, 21 isolates of

Analysis of Polymorphism of 18S rRNA Gene in Wuchereria bancrofti Microfilariae

Microbiology and Immunology, 2005
AbstractThe polymorphism of the 18S rRNA gene in Wuchereria bancrofti microfilariae (mf) collected from three different zones in India was analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The RFLPs of the amplified products obtained after digestion with restriction enzymes SspI, MspI and HhaI showed no ...

Re-analysis of the 18S rRNA gene phylogeny of the ciliate class Colpodea

European Journal of Protistology, 2019
We critically re-analyzed the 18S rRNA gene phylogeny of the ciliate class Colpodea where four main lineages have been recognized: (1) Bursariomorphida including bryometopids, (2) Platyophryida including sorogenids, (3) Cyrtolophosidida, and (4) Colpodida including bryophryids and grossglockneriids.
