The alignment of the 28S gene of several species of Pezizales allowed to select two pairs of primers able to amplify the internal transcribed spacer region of ribosomal DNA in mycorrhizal fungi, such as truffles. The higher yield of the amplification product demonstrates a better annealing of the new primers to the rDNA, as compared to the universal primers internal transcribed spacer 1 and int...
گونه های مخمری نقش مهمی را در مرگ و میر بیماران دارای نقص ایمنی ایفا می کنند. در مطالعه حاضر از پلی مورفیسم قطعات طولی internal transcribed spacer موجود در dna ریبوزومی برای شناسایی مهمترین و شایع ترین گونه های مخمری پزشکی از میان نمونه های بالینی استفاده شده است. نواحی its1 و its2 214 سوش قارچی شامل 30 سوش استانداردو 184 نمونه بالینی توسط روش pcr با استفاده از دو جفت پرایمر (its1-its2) و (its...
OBJECTIVES In addition to several molecular methods and in particular 16S rDNA analysis, the application of a more discriminatory genetic marker, i.e., 16S-23S internal transcribed spacer gene sequence has had a great impact on identification and classification of mycobacteria. In the current study we aimed to apply this sequencing power to conclusive identification of some Iranian clinical str...
The historical biogeography of Scabiosa (Dipsacaceae): implications for Old World plant disjunctions
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...
Three dictyostelid isolates were found in Spain and Argentina that are morphologically different from known species. These isolates have some features similar to Dictyostelium sphaerocephalum (Oudem.) Sacc., Marchal & É.J. Marchal, but differ in size and sorocarp branching pattern. We sequenced the nuclear ribosomal internal transcribed spacer region to explore phylogenetic relationships among ...
