Ribosomal DNA intergenic spacer of indoor wood-decay fungi

hfsg, 2008
Abstract Indoor wood-decay fungi are economically very important. Approximately half of the total damage caused by indoor fungi in Germany is caused by species of the Coniophoraceae. The sequence of the intergenic spacer (IGS) region of the ribosomal DNA was elucidated with the following fungi of this family: Serpula lacrymans (true dry ...

Typing truffle species by PCR amplification of the ribosomal DNA spacers

Mycological Research, 1994
Variation within the internal transcribed spacer (ITS) and the intergenic spacer (IGS) of the ribosomal RNA genes of European species of Tuber was examined by polymerase chain reaction (PCR) and coupled restriction fragment length polymorphism (RFLP) analysis.

Ribosomal DNA spacer-length variation inSecale spp. (Poaceae)

Plant Systematics and Evolution, 1990
Variation in ribosomal DNA spacer length was analysed in 23 populations of 12Secale spp. by restriction enzyme analysis. Digestion of rDNA with Taq I endonuclease enzyme yields spacer fragments that include the subrepeat array and the non-repetitive region downstream of the array.

Molecular Phylogenetic Analysis of Ixodid Ticks Based on the Ribosomal DNA Spacer, Internal Transcribed Spacer 2, Sequences

The Journal of Parasitology, 2000
An internal transcribed spacer (ITS2) sequence between the 5.8S and 28S rRNA genes was used to estimate the phyletic relationships among Ixodes spp. tick vectors of Lyme disease-causing Borrelia spirochetes. Analysis indicates that Borrelia burgdorferi sensu lato species associated with Lyme disease are found mainly in ticks of the Ixodes ricinus ...

Ribosomal DNA spacer probes for yeast identification: Studies in the genus Metschnikowia

Yeast, 1991
AbstractTo test whether DNA probes derived from ribosomal DNA spacer sequences are suitable for rapid and species‐specific yeast identification, a pilot study was undertaken. A 7·7 kb entire ribosomal DNA unit of the type strain of Metschnikowia reukaufii was isolated, cloned and mapped.

Conservation of intergenic spacer length in ribosomal DNA of the tailed frog, Ascaphus truei

Gene, 1992
We have examined the organization of cloned rDNA [encoding ribosomal RNA (rRNA)] repeat units from the tailed frog, Ascaphus truei, and have compared rDNA spacer lengths in the genomes of eleven individuals from two widely-separated populations. This comparison has shown that the A.

Why Nuclear Ribosomal DNA Spacers (ITS) Tell Different Stories in Quercus

Molecular Phylogenetics and Evolution, 2001
The molecular systematics of Quercus (Fagaceae) was recently assessed by two teams using independently generated ITS sequences. Although the results disagreed in several remarkable features, the phylogenetic trees for either hypothesis were highly supported by bootstrap resampling. We have reanalyzed the ITS sequences used by both teams (eight taxa) to

Ribosomal DNA ITS-1 Intergenic Spacer Polymorphism in Triatomines (Triatominae, Heteroptera)

Biochemical Genetics, 2005
The length polymorphism of ribosomal DNA ITS-1 intergenic spacer was analyzed in eight species of triatomines belonging to Triatoma, Rhodnius, and Panstrongylus genera. The analyzed species were Rhodnius domesticus, R. neivai, R. robustus, Triatoma brasiliensis, T. infestans, T. vitticeps, Panstrongylus megistus, and P. herreri.

Evolution of Repeated Sequences in the Ribosomal DNA Intergenic Spacer of 32 Arthropod Species

Journal of Molecular Evolution, 2010
The evolution of a multigene family (MGF) is affected by the structure and function of its regulatory elements, specifically by the link between recombination and DNA transcription and/or replication. The ribosomal DNA (rDNA) MGF is often hierarchically repetitive, combining function with repetition in a single genic system.

The structure and evolution of the ribosomal DNA intergenic spacer in arthropods

The tandemly repeated ribosomal DNA (rDNA) multigene family (MGF) contains the transcription unit of the 45S ribosomal RNA (rRNA) precursor alternating with an intergenic spacer (IGS) that frequently contains iterated regulatory elements. Although the rRNA coding sequences are highly conserved, the IGS displays the high rates of interspecific sequence ...
