Genome doubling (polyploidy) has been and continues to be a pervasive force in plant
evolution. Modern plant genomes harbor evidence of multiple rounds of past …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Allotetraploid oilseed rape (Brassica napus L.) is an agriculturally important crop. Cultivation
and breeding of B. napus by humans has resulted in numerous genetically diverse …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms …

Polyploidy is a common mode of evolution in flowering plants. The profound effects of
polyploidy on gene expression appear to be caused more by hybridity than by genome …

We have used an∼ 8.7-Mb BAC contig of Arabidopsis thaliana Chromosome 4 to trace
homeologous chromosome regions in 21 species of the family Brassicaceae. Homeologs of …

Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

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 …

Association genetics can quickly and efficiently delineate regions of the genome that control
traits and provide markers to accelerate breeding by marker-assisted selection. But most …
