Premise of the Study Recurrent formation of polyploid taxa is a common observation in many
plant groups. Haploid, cytoplasmic genomes like the plastid genome can be used to …

The origin and evolution of polyploids have been studied extensively in angiosperms and
ferns but very rarely in gymnosperms. With the exception of three species of conifers, all …

In a cross between two homozygous Brassica napus plants of synthetic and natural origin,
we demonstrate that novel structural genome variants from the synthetic parent cause …

Abstract Background and Aims The distribution of polyploidy along a relatively steep
Andean elevation and climatic gradient is studied using the genus Fosterella LB …

Abstract Background and Aims The distribution of cytotypes and its potential correlation with
environmental variables represent a cornerstone to understanding the origin and …

Abstract Background and Aims Whole-genome duplication is known to influence ecological
interactions and plant physiology; however, despite abundant case studies, much is still …

In spite of their success during the past several millions of years, recent analyses indicate
that polyploid species may have higher extinction rates than their diploid relatives. The idea …

The diploid D-genome lineage of the Triticum/Aegilops complex has an evolutionary history
involving genomic contributions from ancient A-and B/S-genome species. We explored here …

The wide geographical distribution of many fern species is related to their high dispersal
ability. However, very limited studies surveyed biological traits that could contribute to …

Gene content in genomes changes through several different processes, with gene
duplication being an important contributor to such changes. Gene duplication occurs over a …
