Phylogeny of γ-proteobacteria inferred from comparisons of 3’ end 16S rRNA gene and 5’ end 16S-23S ITS nucleotide sequences
The phylogeny of γ-proteobacteria was inferred from nucleotide sequence comparisons of a short 232 nucleotide sequence marker. A total of 64 γ-proteobacterial strains from 13 Orders, 22 families, 40 genera and 59 species were analyzed. The short 232 nucleotide sequence marker used here was a combination of a 157 nucleotide sequence at the 3’ end of the 16S rRNA gene and a 75 nucleotide sequence...
متن کاملPhylogeny of the Order Bacillales inferred from 3’ 16S rDNA and 5’ 16S-23S ITS nucleotide sequences
A short 220 bp sequence was used to study the taxonomic organization of the bacterial Order Bacillales. The nucleotide sequences of the 3’ end of the 16S rDNA and the 16S-23S Internal transcribed spacer (ITS) were determined for 32 Bacillales species and strains. The data for 40 additional Bacillales species and strains were retrieved directly from Genbank. Together, these 72 Bacillales species...
متن کاملPhylogenetic relationships between Bacillus species and related genera inferred from comparison of 3' end 16S rDNA and 5' end 16S-23S ITS nucleotide sequences.
The nucleotide sequences of the 3' end of the 16S rDNA and the 16S-23S internal transcribed spacer (ITS) of 40 Bacillaceae species were determined. These included 21 Bacillus, 9 Paenibacillus, 6 Brevibacillus, 2 Geobacillus, 1 Marinibacillus and 1 Virgibacillus species. Comparative sequence analysis of a 220 bp region covering a highly conserved 150 bp sequence located at the 3' end of the 16S ...
متن کاملGenetic variations of avian Pasteurella multocida as demonstrated by 16S-23S rRNA gene sequences comparison
Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida isolates...
متن کاملHigher-level snake phylogeny inferred from mitochondrial DNA sequences of 12S rRNA and 16S rRNA genes.
Portions of two mitochondrial genes (12S and 16S ribosomal RNA) were sequenced to determine the phylogenetic relationships among the major clades of snakes. Thirty-six species, representing nearly all extant families, were examined and compared with sequences of a tuatara and three families of lizards. Snakes were found to constitute a monophyletic group (confidence probability [CP] = 96%), wit...
