from 18S rRNA Sequences
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 fulllength 18S rRNA sequence for 84 species of Hydradephaga, including representatives of most major groups down to the tribal level, and a total o...
متن کاملNucleotide sequence of the region between the 18S rRNA sequence and the 28S rRNA sequence of rat ribosomal DNA.
The DNA sequence of the intragenic region of the rat 45S ribosomal RNA precursor was determined. This sequence contains 2282 nucleotides and extends from the conserved EcoR I site near the 3' terminus of 18S rRNA to 69 nucleotides downstream of the 5' terminus of 28S rRNA. The sequences corresponding to 18S and 5.8S rRNA were identified by comparison with previously published data. The 5' termi...
متن کاملPhylogenetic relationships of basal hexapods reconstructed from nearly complete 18S and 28S rRNA gene sequences.
This study combined nearly complete 28S and 18S rRNA gene sequences (>4100 nt long) to investigate the phylogenetic relationships of basal hexapods (Protura, Collembola, and Diplura). It sequenced more 28S genes, to expand on a previous study from this lab that used 18S plus only a tiny part of the 28S gene. Sixteen species of basal hexapods, five insects, six crustaceans, two myriapods, and tw...
متن کاملDetection of fungal 18S rRNA sequences in conjunction with marine nematode 18S rRNA amplicons
Free-living nematodes constitute an important component of estuarine and marine benthic ecosystems. Some marine and soil nematodes are known to harbor microbes, including symbiotic bacteria and fungi, in their external cuticle as well as internally. While assessing diversity of marine nematodes from southwest England using molecular approaches, we found evidence of coamplification of fungal 18S...
متن کاملPhylogeny of some ascaridoid nematodes, inferred from comparison of 18S and 28S rRNA sequences.
Reverse transcription of cellular RNA was used to obtain sequences from regions of 18S and 26/28S ribosomal RNA for eight species of ascaridoid nematodes. Phylogenetic relationships among these species were inferred from the aligned sequences by maximum-parsimony and maximum-likelihood methods. Seventy-nine of the 168 sites that varied were phylogenetically informative in parsimony analysis. Ph...
