The Cucurbita maxima ribosomal DNA intergenic spacer has a complex structure
Gene, 1989The nucleotide (nt) sequence of the 5508-nt intergenic spacer (IGS), between the 25S- and the 18S-coding regions of Cucurbita maxima rDNA, was determined. The fragment sequenced is 6142 nt long and includes 472 nt of 25S- and 162 nt of 18S-coding regions.

Ribosomal DNA intergenic spacer of indoor wood-decay fungi
hfsg, 2008Abstract 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 ...

Respiratory-competent yeast mitochondrial DNAs generated by deleting intergenic regions
Gene, 1989Two respiratory-competent yeast strains having mitochondrial (mt) DNA characterized by single non-overlapping deletions, encompassing intergenic sequences, have been crossed. Diploid daughter clones have been screened by electrophoresis of mtDNA fragments, and a respiratory-competent clone (ER8.75), having a recombinant small mtDNA with both parental ...

Analytical Biochemistry, 2012
The untranscribed DNA sequences of the intergenic spacer regions (ISRs) in the groESL gene of 23 Vibrio species were determined and compared. ISR sequence length (41-85 bp) was variable. Vibrio species could be divided into three groups according to the length and homology of their ISR sequences.

Transcription of ribosomal DNA intergenic spacer sequences in normal and regenerating rat liver
Biochemical and Biophysical Research Communications, 1991In regenerating rat liver both the transcriptional activity of the intergenic spacer rDNA promoter and the steady-state abundance of spacer transcripts are increased about 2-fold, as compared to normal liver. These changes are parallel to the observed 2.5-fold increase in regenerating liver of rRNA gene promotor activity and gene promotor transcripts ...

Conservation of intergenic spacer length in ribosomal DNA of the tailed frog, Ascaphus truei
Gene, 1992We 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.

Ribosomal DNA ITS-1 Intergenic Spacer Polymorphism in Triatomines (Triatominae, Heteroptera)
Biochemical Genetics, 2005The 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, 2010The 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 ...openaire +1 more source
