Characterisation of Angiostrongylus cantonensis Isolates from China by Sequences of Internal Transcribed Spacers of Nuclear Ribosomal DNA

PHYLOGENETIC RELATIONSHIPS BETWEEN IRANIAN ISOLATES OF MICROSPHAERA AND ERYSIPHE S. LAT. BASED ON rDNA INTERNAL TRANSCRIBED SPACERS SEQUENCES

To study the phylogenetic relationships between Erysiphe s. lat. and Microsphaera, the nucleotide sequences of internal transcribed spacers ofrDNA including 5.8S rDNA gene were determined for 23 taxa. The results showed that Erysiphe. section Erysiphe and Microsphaera are closely related and clustered together with strong bootstrap support (100%). All oftaxa belonging to this group produce coni...

Evolution of ribosomal internal transcribed spacers in Deuterostomia.

Sequences of ribosomal internal transcribed spacers (ITSs) are of great importance to molecular phylogenetics and DNA barcoding, but remain unstudied in some large taxa of Deuterostomia. We have analyzed complete ITS1 and ITS2 sequences in 62 species from 16 Deuterostomia classes, with ITS sequences in 24 species from 11 classes initially obtained using unannotated contigs and raw read sequence...

Limits of nuclear ribosomal DNA internal transcribed spacer (ITS) sequences as species barcodes for Fungi.

In PNAS, the work by Schoch et al. (1) proposed nuclear ribosomal DNA internal transcribed spacer (ITS) sequences as the sole universal barcode for fungi. The work by Schoch et al. (1) stated that “the proposal will satisfy most fungal biologists but not all” (1). I am among those biologists who are not so satisfied and not really surprised either, because ITS has been the most widely used mark...
