[HTML][HTML] Intragenomic rDNA variation-the product of concerted evolution, mutation, or something in between?
The classical model of concerted evolution states that hundreds to thousands of ribosomal
DNA (rDNA) units undergo homogenization, making the multiple copies of the individual …

[HTML][HTML] Does intraspecific variation in rDNA copy number affect analysis of microbial communities?
Amplicon sequencing of partial regions of the ribosomal RNA loci (rDNA) is widely used to
profile microbial communities. However, the rDNA is dynamic and can exhibit substantial …

5S‐IGS rDNA in wind‐pollinated trees (Fagus L.) encapsulates 55 million years of reticulate evolution and hybrid origins of modern species
Standard models of plant speciation assume strictly dichotomous genealogies in which a
species, the ancestor, is replaced by two offspring species. The reality in wind‐pollinated …
