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

Phylogeny of the Sporobolus indicus complex, based on internal transcribed spacer (ITS) sequences

Australian Systematic Botany, 2003
The entire internal transcribed spacer (ITS) region, including the 5.8S subunit of the nuclear ribosomal DNA (rDNA), was sequenced by direct double-stranded sequencing of polymerase chain reaction (PCR) amplified fragments. The study included 40 Sporobolus (Family Poaceae, subfamily Chloridoideae) seed collections from 14 putative species (all 11 ...

Comparison of the Internal Transcribed Spacer, ITS-1, from Sarcocystis falcatula Isolates and Sarcocystis neurona

The Journal of Parasitology, 1999
The genetic diversity among 6 Sarcocystis falcatula isolates derived from geographically distinct regions in the U.S.A. was detected using the first internal transcribed spacer region 1 (ITS-1) of the rRNA gene. These sequences were then compared to the full sequence from a Sarcocystis neurona isolate obtained from a California horse diagnosed with ...

Differences in the Second Internal Transcribed Spacer (ITS-2) of Eight Species of Gastrointestinal Nematodes of Ruminants

The Journal of Parasitology, 1999
Genetic differences in the nucleotide sequence of the second internal transcribed spacers (ITS-2) among Trichostrongylus axei, Trichostrongylus colubriformis, Ostertagia ostertagi, Cooperia oncophora, Cooperia punctata, Nematodirus helvetianus, Nematodirus filicollis, and Haemonchus contortus are described.

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.

Differentiation of two ovine Babesia based on the ribosomal DNA internal transcribed spacer (ITS) sequences

Experimental Parasitology, 2009
The first and second internal transcribed spacers (ITS1, ITS2) as well as the intervening 5.8S coding region of the rRNA gene for six Babesia spp. isolated from different geographic origins were characterized. Varying degrees of ITS1 and ITS2 intra- and inter-species sequence polymorphism were found among these isolates.

Distribution of Candida in the oral cavity and its differentiation based on the internally transcribed spacer (ITS) regions of rDNA

Yeast, 2012
AbstractThis study aimed to determine the distribution of Candida species in the oral cavity and differentiate the species based on PCR amplification, including HinfI and MspI digestion, in order to assess the effectiveness of using the rDNA region for species identification.
