The structure of the maize ribosomal DNA spacer region
Nucleic Acids Research, 1986 A combination of a single stranded plasmid vector and ordered deletions were used to determine the complete nucleotide sequence of a rDNA spacer region isolated from the DNA of maize Black Mexican Sweet suspension cells. The sequence reveals the presence of ten "200 base" subrepeats within the maize rDNA spacer region.

Cloning and sequencing of the complicated rDNA gene family of Bos taurus
Czech Journal of Animal Science, 2006 The rDNA genes coding for ribosomal RNA (rRNA) in animals are repeat sequences with high GC content and complicated structure. Based on the sequences of human ribosomal DNA repeat unit and transcription unit and the long and accurate PCR method with LA ...

Molecular Diversity of Mold Associated with Gatotan
Microbiology Indonesia, 2021 Gatotan is a raw material to make gatot, an Indonesian fermented food, especially in Central Java, made from cassava tubers. Traditionally, the cassava tubers are sun-dried for several days until the black color appears.

Transcription of spacer sequences flanking the rat 45S ribosomal DNA gene. [PDF]
Molecular and Cellular Biology, 1987 The transcriptional activity of spacer sequences flanking the rat 45S ribosomal DNA (rDNA) gene were studied. Nascent RNA labeled in in vitro nuclear run-on reactions hybridized with both 5' and 3' spacer regions. The highest level of hybridization was seen with an rDNA fragment containing tandem repeats of a 130-base-pair sequence upstream of the 45S ...

Telomere and ribosomal DNA repeats are chromosomal targets of the bloom syndrome DNA helicase
BMC Cell Biology, 2003 Background Bloom syndrome is one of the most cancer-predisposing disorders and is characterized by genomic instability and a high frequency of sister chromatid exchange. The disorder is caused by loss of function of a 3' to 5' RecQ DNA helicase, BLM. The

Restriction analysis of spacers in ribosomal DNA of Drosophila melanogaster
Nucleic Acids Research, 1979 The sequence arrangement of ribosomal DNA (rDNA) spacers in Drosophila melanogaster was analyzed with restriction endonucleases. Spacers, derived from cloned rDNA repeats and from uncloned purified rDNA, are internally repetitive, as demonstrated by the regular 250 base pairs interval between sites recognized by the enzyme Alu I.

Evaluation of five regions as DNA barcodes for identification of Lepista species (Tricholomataceae, Basidiomycota) from China [PDF]
PeerJ, 2019 Background Distinguishing among species in the genus Lepista is difficult because of their similar morphologies. Methods To identify a suitable DNA barcode for identification of Lepista species, we assessed the following five regions: internal ...

New Microbes and New Infections, EarlyView., 2014 Abstract We describe a case of fungal keratitis due to Beauveria bassiana in a farmer with Fuchs' dystrophy, treated with amphotericin B. Surgery with penetrating keratoplasty was necessary to resolve the lesions. Susceptibility testing and molecular sequencing permitted the identification and treatment of this rare aetiological agent of invasive ...

Acid digestion and symbiont: Proton sharing at the origin of mitochondriogenesis?
BioEssays, Volume 45, Issue 1, January 2023., 2023 ADMit hypothesis for the origin of eukaryotes. A bacterial symbiont became associated with a protophagocytic host that captured prey with membrane processes. The symbiont cooperated to kill and digest the prey with reactive oxygen species and the acidification of the microenvironment.
