Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution
Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

The advantages and disadvantages of being polyploid
L Comai - Nature reviews genetics, 2005 - nature.com
Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

The B73 maize genome: complexity, diversity, and dynamics
We report an improved draft nucleotide sequence of the 2.3-gigabase genome of maize, an
important crop plant and model for biological research. Over 32,000 genes were predicted …

Polyploidy: pitfalls and paths to a paradigm
Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

The polyploidy revolution then… and now: Stebbins revisited
Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

Subgenome dominance in an interspecific hybrid, synthetic allopolyploid, and a 140-year-old naturally established neo-allopolyploid monkeyflower
Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

Widespread paleopolyploidy in model plant species inferred from age distributions of duplicate genes
It is often anticipated that many of today's diploid plant species are in fact paleopolyploids.
Given that an ancient large-scale duplication will result in an excess of relatively old …
