Comparative studies of the nucleotide sequences of ribosomal RNA (rRNA) genes provide a
means for analyzing phylogenetic relationships over a wide range of taxonomic levels …

Nucleotide sequences of the small subunit ribosomal RNA (18S) gene were used to
investigate evolutionary relationships within the Fungi. The inferred tree topologies are in …

Nuclear ribosomal genes in most eukaryotes are present in multiple copies and often used
for taxonomic and phylogenetic analyses. We comprehensively examined intragenomic …

We compiled a 5.8 S nuclear ribosomal gene sequence database for animals, plants, and
fungi using both newly generated and GenBank sequences. We demonstrate the utility of …

ABSTRACT rRNA genes are attractive targets for developing PCR assays targeting human
fungal pathogens. Most studies have focused on the 18S rRNA gene, internal transcribed …

Publisher Summary The inference of phylogenetic relationships from molecular data is
contributing greatly in understanding the evolution of life on Earth. Although the discussion …

Nucleic acid sequencing technology is bringing a much-needed phylogenetic perspective
into microbiology. There is no more fundamental and straightforн ward way to classify and …

Intragenomic variation is the molecular variation within the genome among repetitive DNA.
As a multigene family, nuclear ribosomal DNA (rDNA) has been widely used in fungal …

Background Gene conversion is the mechanism proposed to be responsible for the
homogenization of multigene families such as the nuclear ribosomal gene clusters. This …

Abstract Ribosomal Database Project (RDP; http://rdp. cme. msu. edu/) provides the
research community with aligned and annotated rRNA gene sequence data, along with tools …
