Internal transcribed spacer 1 and 2 (ITS1 and ITS2) sequences were analysed in Ensis razor shells (Mollusca: Bivalvia: Pharidae). We aimed to (1) test ITS1 and ITS2 as molecular markers at the population level in the successful alien E. directus (Conrad, 1843); (2) test these spacers at the species level in E. directus and three other Ensis species, E. siliqua (L., 1758), E. macha (Molina, 1782...

anopheles fluviatilis complex is known to be a vector of malaria in iran. since mosquitoes of this species cover a wide geographical range in iran, they might have evolved into different separated populations. random amplified polymorphic dna polymerase chain reaction (rapd-pcr) assay was used to differentiate geographic populations of this species. dna was extracted from individual mosquitoes ...

The class Litostomatea is a highly diverse ciliate taxon comprising hundreds of free-living and endocommensal species. However, their traditional morphology-based classification conflicts with 18S rRNA gene phylogenies indicating (1) a deep bifurcation of the Litostomatea into Rhynchostomatia and Haptoria+Trichostomatia, and (2) body polarization and simplification of the oral apparatus as main...

Two new Stephanostomum-like cercariae, Cercaria capricornia VII and Cercaria capricornia VIII (Digenea: Acanthocolpidae), are described from the nassariid gastropods Nassarius dorsatus and Nassarius olivaceus collected from the intertidal zone in the Capricornia region of Central Queensland, Australia. Morphological analysis of these new cercariae was augmented with DNA sequence data from the l...

We introduce an open source software utility to extract the highly variable ITS1 and ITS2 subregions from fungal nuclear ITS sequences, the region of choice for environmental sampling and molecular identification of fungi. Inclusion of parts of the neighbouring, very conserved, ribosomal genes in the sequence identification process regularly leads to distorted results. The utility is available ...

DNA sequencing analyses have demonstrated relatively limited polymorphisms within the fungal internal transcribed spacer (ITS) regions among Trichophyton spp. We sequenced the ITS region (ITS1, 5.8S, and ITS2) for 42 dermatophytes belonging to seven species (Trichophyton rubrum, T. mentagrophytes, T. soudanense, T. tonsurans, Epidermophyton floccosum, Microsporum canis, and M. gypseum) and deve...

In central China, Anopheles anthropophagus is considered the primary malaria vector andAnopheles sinensis is a secondary vector. IdentiÞcation of these twocryptic specieswould facilitate studies on malaria transmission and the application of control measures. At present, the only reliable morphological markers occur in the egg stage, making this approach impractical for any large scale Þeld stu...

‘Vidari’ is an Ayurvedic herbal drug used as aphrodisiac and galactagogue. It is also used in the preparation of Chyavanaprash, an Ayurvedic Nutraceutical. Ayurvedic Pharmacopeia of India correlates tubers of Pueraria tuberosa (Roxb. ex Willd.) DC (Fabaceae) as ‘Vidari’ and Ipomoea mauritiana Jacq. (Convolvulaceae) as Kshiravidari, used as a substitute for Vidari in some parts of India. Tubers ...

Molecular studies of six species from the ancient extant seed plant Cycas, covering a wide range of its morphological diversity and all major areas of distribution, revealed a high level of intra-individual polymorphism of the internal transcribed spacer (ITS1, 5.8S, and ITS2) region, indicative of incomplete nrDNA concerted evolution. Through a range of comparisons of sequence characteristics ...

The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. In this study, DNA sequence data and polymerase chain reaction (PCR) were utilized to develop a molecular diagnostic marker for S. dorsalis. The DNA sequence variation from the internal transcribed spacer 2 (ITS2) region of nuclear ribosom...
