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.

Ribosomal DNA Intergenic Spacer of the Swimming Crab, Charybdis japonica

Journal of Molecular Evolution, 1999
We have determined the full sequence of the ribosomal DNA intergenic spacer (IGS) of the swimming crab, Charybdis japonica, by long PCR for the first time in crustacean decapods. The IGS is 5376 bp long and contains two nonrepetitive regions separated by one long repetitive region, which is composed mainly of four subrepeats (subrepeats I, II, III, and

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 ...

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

Restriction analysis of the nontranscribed spacers of Xenopus laevis ribosomal DNA

Cell, 1977
Abstract We have studied sequence organization in the nontranscribed spacer regions of four cloned fragments of Xenopus laevis ribosomal DNA. Each clone contains a spacer of different length. The distribution of cleavage sites for several restriction endonucleases have been investigated in these spacers.

Complex structure of the ribosomal DNA spacer of Cucumis sativus (cucumber)

Molecular and General Genetics MGG, 1988
The nuclear 18 S, 5.8 S and 25 S ribosomal RNA genes (rDNA) of Cucumis sativus (cucumber) occur in at least four different repeat types of 10.2, 10.5, 11.5, and 12.5 kb in length. The intergenic spacer of these repeats has been cloned and characterized with respect to sequence organization.

The Cucurbita maxima ribosomal DNA intergenic spacer has a complex structure

Gene, 1989
The 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.

Cell-Specific Ribosomal DNA Spacer Variability in Human Urothelial Carcinoma Cultures

Journal of Urology, 1987
Length variation of a ribosomal DNA "spacer" region in four chromosomally characterized transitional cell carcinoma cultures was analyzed by restriction endonuclease cleavage and Southern blotting. Cell lines with relative karyotypic conservation, such as UM-UC-2 (modal chromosome number 48, four marker chromosomes) demonstrate little change in the ...

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.

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 ...
