The internal transcribed spacer (ITS) region of the nuclear rDNA cistrons is one of the more
frequently utilized regions for phylogenetic analyses at the genus and species levels. It has …

DNA sequences, powerful for phylogeny, have not yet proven as rewarding for taxonomic
categorization purposes. However, further analyses of one locus, the second Internal …

The internal transcribed spacer 2 (ITS2) of the nuclear ribosomal repeat unit is one of the
most commonly applied phylogenetic markers. It is a fast evolving locus, which makes it …

Background In sequence analysis the multiple alignment builds the fundament of all
proceeding analyses. Errors in an alignment could strongly influence all succeeding …

For evolutionary comparisons, phylogenetics and evaluation of potential interbreeding taxa
of a species, various loci have served for animals and plants and protistans. One [second …

Given two organisms, how can one distinguish whether they belong to the same species or
not? This might be straightforward for two divergent organisms, but can be extremely difficult …

The nuclear ribosomal locus coding for the large subunit is represented in tandem arrays in
the plant genome. These consecutive gene blocks, consisting of several regions, are widely …

To understand how allopatric speciation proceeds, we need information on barriers to gene
flow, their antiquity, and their efficacy. For marine organisms with planktonic larvae, much of …

The information that can be obtained from the secondary structure of the nuclear ribosomal
internal transcribed spacer 2 (ITS2) is substantial, and yet many studies exploit this …

Compensatory base changes (CBCs) in internal transcribed spacer 2 (ITS2) rDNA
secondary structures correlate with Ernst Mayr's biological species concept. This hypothesis …
