Restriction analysis of spacers in ribosomal DNA of Drosophila melanogaster

open access: yesNucleic 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.

Single Strand Conformation Polymorphism Method for Initial Detection DNA Sequences Homogeneity

open access: yesHayati Journal of Biosciences, 2010
In molecular phylogenetic study, homogeneity of DNA sequences is a prerequisite before putting it into practice. Internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) has been common in phylogenetic study, but a homogenous sequence is

A phylogeny of Uniolinae with a new genus, Eragrostiola and combination, E. spicata (Poaceae, Chloridoideae, Eragrostideae, Uniolinae) [PDF]

open access: yesPhytoKeys
We present a molecular DNA phylogeny of Uniola utilizing three plastid (rps16-trnK spacer, rps16 intron, rpl32-trnL spacer) and the nuclear ribosomal internal transcribed spacer (ITS) regions investigating 87 species of tribe Eragrostideae, including an ...

Evaluation of five regions as DNA barcodes for identification of Lepista species (Tricholomataceae, Basidiomycota) from China [PDF]

open access: yesPeerJ, 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 ...
