Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution

AS Mason, JF Wendel - Frontiers in Genetics, 2020 - frontiersin.org
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 polyploidy revolution then… and now: Stebbins revisited

DE Soltis, CJ Visger, PS Soltis - American journal of botany, 2014 - Wiley Online Library
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

PP Edger, R Smith, MR McKain, AM Cooley… - The Plant …, 2017 - academic.oup.com
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

G Blanc, KH Wolfe - The plant cell, 2004 - academic.oup.com
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 …
