Rapid and accurate identification of Staphylococcus species by tRNA intergenic spacer length polymorphism analysis.
PCR-amplified tRNA gene (tDNA) intergenic spacer length polymorphism (tDNA-ILP) was analyzed for its ability to identify to the species level type strains (n = 18) and clinical isolates (n = 163) of staphylococci. Amplified products obtained by PCR with outwardly directed consensus tDNA primers were separated by agarose and polyacrylamide gel electrophoreses. The results were compared with thos...
متن کاملRibosomal DNA (rDNA) spacer polymorphism in mole rats.
Genetic differentiation of ribosomal DNA (rDNA) nontranscribed-spacer (NTS) polymorphism was analyzed in 50 individuals from 13 populations among the four chromosomal species (2n = 52, 2n = 54, 2n = 58, and 2n = 60) of subterranean mole rats of the Spalax ehrenbergi complex in Israel. Southern blot analysis with a mouse rDNA probe and two restriction enzymes, EcoRI and BamHI, revealed various s...
متن کاملStructural and functional characterization of the intergenic spacer region of the rDNA in Daucus carota.
The intergenic spacer (IGS) region of rDNA in Daucus carota contains at least eight kinds of repeated sequence. One sequence may act as a genuine initiation site for a stable transcript and another may act as a spacer promoter that may be an entry site for proteins required for transcription.
متن کاملDifferential Identification of Flavobacterium Species by Sequence Analysis of Genus-Specific Hypervariable 16S-23S rDNA Intergenic Spacer Target
The aim of the current study was to develop a molecular system for differential identification of various fish diseases caused by Flavobacterium species. The system uses the hypervariability of the 16S-23S rDNA Intergenic spacer region (ISR) to develop PCR-based sequence analysis assay. For this purpose, eight different 16S-23S rDNA ISR sequences of six different Flavobacterium species were ali...
متن کاملEvaluation of seven DNA barcodes for differentiating closely related medicinal Gentiana species and their adulterants
BACKGROUND Species identification of living organisms by standard DNA sequences has been well-accepted. Consortium for the Barcode of Life (CBOL) recommends chloroplast regions rbcL and matK as the DNA barcodes for the land plants. This study aims to evaluate the feasibility and limitations of rbcL, matK, and 5 other commonly used regions as the DNA barcodes for the medicinal Gentiana and their...
