Until around 1990, most multigene families were thought to be subject to concerted
evolution, in which all member genes of a family evolve as a unit in concert. However …

A surprisingly large fraction of the eukaryotic genome is repetitive. More than one third of the
human genome consists of interspersed repetitive DNA, and tandemly repeated DNA …

Environmental DNA metabarcoding is a powerful tool for studying biodiversity. However,
bioinformatic approaches need to adjust to the diversity of taxonomic compartments targeted …

Background Identification of species via DNA sequences is the basis for DNA taxonomy and
DNA barcoding. Currently there is a strong focus on using a mitochondrial marker for this …

Analysis of intragenomic variation of 16S rRNA genes is a unique approach to examining
the concept of ribosomal constraints on rRNA genes; the degree of variation is an important …

Although nuclear ribosomal DNA (rDNA) repeats evolve together through concerted
evolution, some genomes contain a considerable diversity of paralogous rDNA. This …

Marine invertebrates representing at least five phyla are symbiotic with dinoflagellates from
the genus Symbiodinium. This group of single-celled protists was once considered to be a …

Because of their simple organization the Acoela have been considered to be either primitive
bilaterians or descendants of coelomates through secondary loss of derived features …

A diverse array of molecular approaches is now available to the plant systematist for use in
phylogenetic inference, including restriction site analysis, comparative sequencing, analysis …

Giardia duodenalis isolates recovered from humans and dogs living in the same locality in a
remote tea-growing community of northeast India were characterized at 3 different loci; the …
