Heterogeneity of the internal transcribed spacer (ITS‐2) region within individual deer ticks

Insect Molecular Biology, 1997
Abstract To determine whether nuclear rDNA sequences provide a useful means for assessing the structure of populations of Ixodes ticks, we compared variability among copies of an internal transcribed spacer (ITS‐2) sequence within individual ticks to the variability between ...

Internal transcribed spacer (ITS) and genetic variations in Lilium native to Korea

Horticulture, Environment, and Biotechnology, 2011
Internal transcribed spacers (ITS) of nuclear ribosomal DNA cistrons were studied in wild Lilium species native to Korea and compared with those species in the genus distributed in other countries to investigate the phylogenetic relationships among Lilium species. Sequence analysis data of Lilium plants collected from China and Japan were also included

Internal Transcribed Spacer (ITS)-PCR Identification of MRSA

2007
Polymerase chain reaction (PCR) analysis of the 16S-23S rRNA gene internal transcribed spacer (ITS) followed by microchip gel electrophoresis was useful for identification of staphylococci and for strain delineation of Staphylococcus aureus. In the study presented in this chapter, 74 ITS patterns were demonstrated among 1,188 isolated colonies of S ...

Phylogenetic Analysis of the Sequences of rDNA Internal Transcribed Spacer (ITS) of Phytophthora sojae

Journal of Genetics and Genomics, 2007
The internal transcribed spacer (ITS) region (ITS1, ITS2 and 5.8S rDNA) of the nuclear ribosomal DNA (nrDNA) was amplified via the PCR method in seventeen different isolates of Phytophthora sojae using the common primers of the ITS of fungi. Around 800 bp-1,000 bp fragments were obtained based on the DL2000 marker and the sequences of the PCR products ...

Secondary Structure Models for the Internal Transcribed Spacer (ITS) Region 1 from Symbiotic Dinoflagellates

Protist, 2010
Ribosomal genes and their spacers have been extensively utilized to examine the biodiversity and phylogenetics of protists. Among these, the internal transcribed spacer regions 1 and 2 (ITS1 and ITS2) are known to form secondary structures that are critically important for proper processing of the pre-rRNA into mature ribosomes.

Comparison of the internal transcribed spacer, ITS 1, from Toxoplasma gondii isolates and Neospora caninum

Parasitology Research, 1997
The internal transcribed spacer (ITS1) region and the 5' part of the 5.8S ribosomal RNA gene of the ribosomal DNA repeat from 20 Toxoplasma gondil isolates was sequenced and found to be identical in all isolates, independent of host origin or virulence to mice. The ITS1 region from the closely related coccidian parasite Neospora caninum differed in 22%

Analysis of internal transcribed spacer (ITS) regions in Steinernema feltiae Sicilian strains.

2023
Biodiversity of entomopathogenic nematodes (EPN) in Italy is particularly high, with a greater number of species (12 species) than in other European and Mediterranean countries (Tarasco et al., 2009). Sicily is the Italian region with the largest number of species, with 6 reported species (Tarasco et. al., 2015). In the last two decades, investigations

GC balance in the internal transcribed spacers ITS 1 and ITS 2 of nuclear ribosomal RNA genes

Journal of Molecular Evolution, 1990
The internal transcribed spacer (ITS) 1 and 2, the 5.8S rRNA gene, and adjacent 18S rRNA and 25S rRNA coding regions of two Cucurbitaceae (Cucurbita pepo, zucchini, ITS 1: 187 bp, and ITS 2: 252 bp in length, and Cucumis sativus, cucumber, ITS 1: 229 bp, and ITS 2: 245 bp in length) have been sequenced.

Internal Transcribed Spacer Region of rDNA in Common Wheat and Its Genome Origins

Acta Agronomica Sinica, 2009
Abstract The objective of this study was to disclose the origin and evolution of the A, B, and D genomes in common wheat (Triticum aestivum L.) with evidence on ribosomal DNA (rDNA) internal transcribed spacer (ITS) sequences. Specific primers were used to amplify the rDNA ITS sequences from common wheat, and 3 types of the amplification fragment ...

Nucleotide polymorphisms associated with Internal Transcribed Spacer (ITS) regions of ocular isolates of Aspergillus flavus

Journal of Microbiological Methods, 2007
To analyse the genetic similarity among ocular isolates of Aspergillus flavus by Polymerase chain reaction based Restriction Fragment Length Polymorphism (PCR-RFLP) and DNA sequencing.Seven ocular isolates of A. flavus from 5 patients (3 from paient 1, and four isolates from patients no.
