BACKGROUND The internal transcribed spacer 2 (ITS2) region of nuclear ribosomal DNA is regarded as one of the candidate DNA barcodes because it possesses a number of valuable characteristics, such as the availability of conserved regions for designing universal primers, the ease of its amplification, and sufficient variability to distinguish even closely related species. However, a general anal...

Abstract Background Brazil is exceptionally abundant in medicinal plant resources and has a rich ethnopharmacological history. Brazilian Pharmacopoeia (BP) acts as national standard that regulates drug quality six published editions. Recent genomic approaches have led to resurgence of interest herbal drugs. The data plants been used for pharmaceutical applications, protecting natural resources,...

The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller collected from 13 Korean and Chinese localities revealed 94 A+T-rich re...

The nuclear ribosomal Internal Transcribed Spacer ITS region is widely used as a DNA metabarcoding marker to characterize the diversity and composition of fungal communities. In amplicon pyrosequencing studies of fungal diversity, one of the spacers ITS1 or ITS2 of the ITS region is normally used. In this methodological study we evaluate the usability of ITS1 vs. ITS2 as a DNA metabarcoding mar...

Our country is home to many endemic plant species including medicinal, aromatic and spice. One of these thyme used both in daily life for medical purposes. the most popular methods phylogenetic classification plants internal transcribed spacer (ITS) region which locates between ITS1 ITS2 regions that highly conserved. In this paper, a was used, grows naturally Sultan Murat Sarıkaya High-plateau...

BACKGROUND Infectivity of herbivores with Trichostrongylus nematodes is widespread in many countries, having a major economic impact on breeding, survivability, and productivity of domestic livestock. This study was carried out on Trichostrongylus species isolated from domestic livestock in order to develop an easy-to-perform method for species identification. METHODS Trichostrongylus isolate...

Sequence variation of the ribosomal DNA internal transcribed spacer 2 (ITS2) was examined for populations of the malaria vector Anopheles nuneztovari collected in Colombia, Venezuela, Bolivia, Suriname, and Brazil. Mosquitoes from Colombia and Venezuela had identical ITS2 sequences and were distinguished from sequences in other populations by three insertion/deletion events (indels) and by one ...

background candida species are normal microflora of  oral cavity, vagina, and gastrointestinal  tract. they are the third most prevalent cause of pediatric health care–associated  bloodstream fungal infection. this study aimed to provide an epidemiological feature of candidiasis and also presents an antifungal susceptibility profile of clinical candida isolates among children. materials and met...

Experimental work pertaining to the molecular cytogenetics of malaria vector species of mosquitoes by the application of PCR technique has been carried out. The main objectives of the study included the sequence characterization of nuclear rDNA internal transcribed spacers 1 and 2 (ITS1, ITS2) and mitochondrial DNA COII gene as potential molecular markers for studying genetic relatedness and ph...
