The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

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 …

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

During the past decade there has been a tremendous resurgence of interest in polyploidy
that has in large part been stimulated by the development of increasingly powerful genetic …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

Polyploidization and recombination are two important processes driving evolution through
the building and reshaping of genomes. Allopolyploids arise from hybridization and …

• Premise of the study: The opuntias (nopales, prickly pears) are not only culturally,
ecologically, economically, and medicinally important, but are renowned for their taxonomic …

Repeat families within genomes are often maintained with similar sequences. Traditionally,
this has been explained by concerted evolution, where repeats in an array evolve “in …

Polyploidy, the possession of more than 2 complete genomes, is a major force in plant
evolution known to affect the genetic and genomic constitution and the phenotype of an …

Microalga are of high relevance for the global carbon cycling and it is well-known that they
are associated with a microbiota. However, it remains unclear, if the associated microbiota …
