Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

The importance of gene duplication in supplying raw genetic material to biological evolution
has been recognized since the 1930s. Recent genomic sequence data provide substantial …

Genome duplication (GD) has permanently shaped the architecture and function of many
higher eukaryotic genomes. The angiosperms (flowering plants) are outstanding models in …

Publisher Summary This discusses the lifecycle, the methods of culture, the isolation of
mutants, the formal genetics, the identification of loci, and the diploids and mitotic …

Polyploidy is a prominent process in plants and has been significant in the evolutionary
history of vertebrates and other eukaryotes. In plants, interdisciplinary approaches …

▪ Abstract Over 35 years ago, Susumu Ohno stated that gene duplication was the single
most important factor in evolution. He reiterated this point a few years later in proposing that …

Through phylogeny reconstruction we identified 49 genes with a single copy in man, mouse,
and chicken, one or two copies in the tetraploid frog Xenopus laevis, and two copies in …

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 …

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 …

Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which
seems to have arisen from one or more cycles of genome doubling. Polyploidy has been …
