Resolution of Prochlorococcus and Synechococcus ecotypes by using 16S-23S ribosomal DNA internal transcribed spacer sequences.
Cultured isolates of the marine cyanobacteria Prochlorococcus and Synechococcus vary widely in their pigment compositions and growth responses to light and nutrients, yet show greater than 96% identity in their 16S ribosomal DNA (rDNA) sequences. In order to better define the genetic variation that accompanies their physiological diversity, sequences for the 16S-23S rDNA internal transcribed sp...
متن کاملLimits of nuclear ribosomal DNA internal transcribed spacer (ITS) sequences as species barcodes for Fungi.
In PNAS, the work by Schoch et al. (1) proposed nuclear ribosomal DNA internal transcribed spacer (ITS) sequences as the sole universal barcode for fungi. The work by Schoch et al. (1) stated that “the proposal will satisfy most fungal biologists but not all” (1). I am among those biologists who are not so satisfied and not really surprised either, because ITS has been the most widely used mark...
متن کاملPhylogenetic relationships of Elymus L. and related genera (Poaceae) based on the nuclear ribosomal internal transcribed spacer sequences
To help in the clarification of the taxonomic status of Elymus L. and related genera Agropyron Gaertn., Leymus Hochst., Hordelymus (Jess.) Harz, and Brachypodium P.Beauv., the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied. ITS data of 64 Triticeae accessions including 40 Elymus, 12 Agropyron, 7 Leymus, and 4 Hordelymus, and 1 Brachypodiu...
متن کاملMolecular characterization of Rhipicephalus (Boophilus) annulatus from Iran by sequences of cytochrome c oxidase subunit I (COI) and the second internal transcribed spacer (ITS2)
Background: Traditionally, morphological features of Rhipicephalus (Boophilus) annulatus from closely-related ticks have been considered for their identification and differentiation. However, it is difficult and requires expertise in order to accurately identify and differentiate engorged female ticks and some developmental stages such as larva and nymph from other similar ticks. Hence, molecul...
متن کاملPolymorphic internal transcribed spacer region 1 DNA sequences identify medically important yeasts.
Species-specific polymorphisms in the noncoding internal transcribed spacer 2 (ITS2) region of the rRNA operon provide accurate identification of clinically significant yeasts. In this study, we tested the hypothesis that ITS1 noncoding regions contain diagnostically useful alleles. The length of ITS1 region PCR products amplified from 40 species (106 clinical strains, 5 reference strains, and ...
