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

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Investigating recombination of homoeologous chromosomes in allopolyploid species is
central to understanding plant breeding and evolution. However, examining chromosome …

Chromosome number is a key feature of the higher-order organization of the genome, and
changes in chromosome number play a fundamental role in evolution. Dysploid gains and …

Abstract Background and Aims To assess the number and phylogenetic distribution of large-
scale genome duplications in the ancestry of Actinidia, publicly available expressed …

Nextgeneration sequencing (NGS) has revolutionized molecular systematics as well as
population and conservation genetics. It is now possible to obtain enormous amounts of …

Evolutionary changes in karyotype provide genetic support to organisms' differentiation and
adaptation; however, the association between karyotype diversity and species diversification …

The study of pollen morphology has historically allowed evolutionary biologists to assess
phylogenetic relationships among Angiosperms, as well as to better understand the fossil …

Karyotype data within a phylogenetic framework and molecular dating were used to
examine chromosome evolution in Nierembergia and to infer how geological or climatic …

To study the origin and evolution of naturally occurring polyploids, we performed
phylogenetic analyses of nuclear ribosomal DNA spacers combined with molecular …
