Plant viral intergenic DNA sequence repeats with transcription enhancing activity [PDF]
Virology Journal, 2005 Background The geminivirus and nanovirus families of DNA plant viruses have proved to be a fertile source of viral genomic sequences, clearly demonstrated by the large number of sequence entries within public DNA sequence databases.

Patterns of Evolutionary Constraints in Intronic and Intergenic DNA of Drosophila [PDF]
Genome Research, 2004 We develop methods to infer levels of evolutionary constraints in the genome by comparing rates of nucleotide substitution in noncoding DNA with rates predicted from rates of synonymous site evolution in adjacent genes or other putatively neutrally evolving sites, while accounting for differences in base composition.

Structure of the intergenic spacers in chicken ribosomal DNA [PDF]
Genetics Selection Evolution, 2019 Background Ribosomal DNA (rDNA) repeats are situated in the nucleolus organizer regions (NOR) of chromosomes and transcribed into rRNA for ribosome biogenesis. Thus, they are an essential component of eukaryotic genomes. rDNA repeat units consist of rRNA

Genomic selective constraints in murid noncoding DNA. [PDF]
PLoS Genetics, 2006 Recent work has suggested that there are many more selectively constrained, functional noncoding than coding sites in mammalian genomes. However, little is known about how selective constraint varies amongst different classes of noncoding DNA.

A discrete class of intergenic DNA dictates meiotic DNA break hotspots in fission yeast.
PLoS Genetics, 2007 Meiotic recombination is initiated by DNA double-strand breaks (DSBs) made by Spo11 (Rec12 in fission yeast), which becomes covalently linked to the DSB ends.

A novel repeated DNA sequence located in the intergenic regions of bacterial chromosomes [PDF]
Nucleic Acids Research, 1990 We report the discovery of a novel group of highly conserved DNA sequences located within the intergenic regions of the chromosomes of Escherichia coli, Salmonella typhimurium and other bacteria. These intergenic repeat units (IRUs) are 124-127 nucleotides long and have the potential to form stable stem-loop structures.

Structure and evolution of the intergenic region in a ribosomal DNA repeat unit of wheat [PDF]
Journal of Molecular Biology, 1988 The complete nucleotide sequence of the intergenic region between the 25 S and 18 S wheat ribosomal RNA genes has been determined from a 4.6 kb EcoRI-BamHI fragment (1 kb = 10(3) bases or base-pairs) subcloned from the plasmid pTa71. Within this subclone the intergenic DNA is flanked by the 3' end of the 25 S and the 5' end of the 18 S ribosomal RNA ...

Statistical analysis of gene and intergenic DNA sequences [PDF]
Physica A: Statistical Mechanics and its Applications, 2004 Much of the on-going statistical analysis of DNA sequences is focused on the estimation of characteristics of coding and non-coding regions that would possibly allow discrimination of these regions. In the current approach, we concentrate specifically on genes and intergenic regions.

Involvement of DNA curvature in intergenic regions of prokaryotes [PDF]
Nucleic Acids Research, 2006 It is known that DNA curvature plays a certain role in gene regulation. The distribution of curved DNA in promoter regions is evolutionarily preserved, and it is mainly determined by temperature of habitat. However, very little is known on the distribution of DNA curvature in termination sites.

Arabidopsis DNA Replication Initiates in Intergenic, AT-Rich Open Chromatin [PDF]
Plant Physiology, 2020 The selection and firing of DNA replication origins play key roles in ensuring that eukaryotes accurately replicate their genomes. This process is not well documented in plants due in large measure to difficulties in working with plant systems. We developed a new functional assay to label and map very early replicating loci that must, by definition ...
