Intraspecific Variation in Commiphora wightii Populations Based on Internal Transcribed Spacer (ITS1-5.8S-ITS2) Sequences of rDNA
Commiphora wightii is an endangered, endemic species found in the Thar Desert of Rajasthan, India and adjoining areas of Pakistan. The populations of this plant are rapidly dwindling due to overexploitation for their medicinally important resin. Analysis of nucleotide sequences of the internal transcribed spacer of rDNAs revealed low genetic diversity ( = 0.03905; w = 0.05418) and high popula...
متن کاملMolecular Identification and Differentiation of Fasciola Isolates Using PCR- RFLP Method Based on Internal Transcribed Spacer (ITS1, 5.8S rDNA, ITS2)
BACKGROUND In this study, we used both ITS1 and ITS2 for molecular identification of Fasciola species. METHODS The region between 18S and 28S of ribosomal DNA was used in PCR-RFLP method for molecular identification of Fasciola species. Ninety trematodes of Fasciola were collected during abattoir inspection from livers of naturally infected sheep and cattle from Khorasan, East Azerbaijan, and...

متن کاملComparison of european Trichobilharzia species based on ITS1 and ITS2 sequences.
Schistosomes are parasites of considerable medical and veterinary importance and, therefore, all aspects of their biology have been intensively studied. In contrast, our knowledge of species of the largest genus, Trichobilharzia, is insufficient. Because morphological characterization of Trichobilharzia species provides a limited number of criteria for species determination, molecular data are ...
متن کاملEvolution of rDNA ITS1 and ITS2 sequences and RNA secondary structures within members of the fungal genera Grosmannia and Leptographium.
The two internal transcribed spacers (ITS) of the nuclear ribosomal (r) DNA tandem repeat were examined in ophiostomatoid fungi belonging to the genera Grosmannia and Leptographium and closely-related taxa. Although the DNA sequence of the ITS region evolves rapidly, core features of the RNA secondary structure of the ITS1 and ITS2 segments are conserved. The results demonstrate that structural...
