Belonolaimus isolates from six U.S. states were compared by restriction endonuclease digestion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based on restriction sites inferred from the nucleotide sequence of a South Carolina Belonolaimus isolate. Amplified product size from individuals of each...

Methods This study uses maximum-likelihood and Bayesian phylogenetic analyses of chloroplast DNA (atpB–rbcL, trnL–trnF, trnS–trnG, psbA–trnH) and nuclear ribosomal DNA [internal transcribed spacer (ITS) and external transcribed spacer (ETS)] from 24 out of c. 37 ingroup taxa, beast molecular dating, and the dispersal–extinction–cladogenesis method (Lagrange) to reconstruct ancestral geographica...

The genus Pseudozyma is an anamorph that belongs to the Ustilaginales. Pseudozyma species are unusual yeast-like fungi and are most frequently isolated from plant materials. The Pseudozyma strain, BCRC 33871, was isolated from the flower of Albizia julibrissin in Taiwan. BCRC 33871 was identified as P. antarctica and described based on morphological, physiological, and molecular data. This disc...

In this article, ITS sequences of 20 species in Osmanthus were cloned and researched. It was found that length of ITS sequences ranged from 614bp to 619bp, in which ITS-1 is obviously longer than ITS-2, 5.8S of 20 species is composed of 163bp, and the percentage of G+C in ITS sequence of 20 species is 54.24%-64.56%. Alignment between ITS sequences from 20 species of Osmanthus was performed, and...

ticks are important acarina that infest animals. they are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. in view of the importance of hyalomma anatolicum anatolicum in pathogen transmission, including th...

The nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) region has been characterized in the sister genera Larix and Pseudotsuga (Pinaceae). Complete sequences were obtained for seven species of Larix from North America and Eurasia and five species of Pseudotsuga from western North America and eastern Asia. ITS region lengths ranged from 1759 to 1770 bp in Larix and from 1564 to 157...

The present findings suggest that Anopheles (Kerteszia) homunculus may comprise more than one species. The rDNA ITS2 sequence data corroborate the presence of An. homunculus l.s. in Mata Atlântica, southern Brazil, and suggest that specimens from Trinidad may belong to an unnamed morphologically similar species. There is a need for additional studies to establish the geographical distribution o...

Internal parasites are considered by some to be one of the most economically important constraints in raising livestock. The growing concern about the resistance of internal parasites to all classes of dewormers has caused people to look for alternatives. As dewormers lose their effectiveness, the livestock community fears increasing economic losses from worms. There is no one thing that can be...
