The phylogenetic position of Siboglinidae (Annelida) inferred from 18S rRNA, 28S rRNA and morphological data

Cladistics, 2004
AbstractWe assess the phylogenetic position of Siboglinidae (previously known as the phyla Pogonophora and Vestimentifera, but now referred to Annelida) in parsimony analyses of 1100 bp from 18S rRNA, 320 bp from the D1 region of 28S rRNA, and 107 morphological characters, totaling 667 parsimony informative characters.

The phylogenetic position of taxaceae based on 18S rRNA sequences

Journal of Molecular Evolution, 1993
The evolutionary position of the yew family, Taxaceae, has been very controversial. Some plant taxonomists strongly advocate excluding Taxaceae from the conifer order and raising its taxonomic status to a new order or even class because of its absence of seed cones, contrary to the case in the majority of conifers.

Phylogeny of Hydradephagan Water Beetles Inferred from 18S rRNA Sequences

Molecular Phylogenetics and Evolution, 2002
Several families in the beetle suborder Adephaga have an aquatic life style and are commonly grouped in the "Hydradephaga," but their monophyly is contentious and relationships between and within these families are poorly understood. Here we present full-length 18S rRNA sequence for 84 species of Hydradephaga, including representatives of most major ...

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 ...

18S rRNA suggests that Entoprocta are protostomes, unrelated to Ectoprocta

Journal of Molecular Evolution, 1996
The Ento- and Ectoprocta are sometimes placed together in the Bryozoa, which have variously been regarded as proto- or deuterostomes. However, Entoprocta have also been allied to the pseudocoelomates, while Ectoprocta are often united with the Brachiopoda and Phoronida in the (super)phylum Lophophorata.

Development of an Argopecten-Specific 18S rRNA Targeted Genetic Probe

Marine Biotechnology, 2000
Comparison of 18S ribosomal RNA gene sequences between diverse bivalve species, including eight scallop species, allowed the design of an 18S rRNA targeted oligonucleotide probe (BS-1364) that was specific for scallops belonging to the genus Argopecten (bay and calico scallops).
