[HTML][HTML] Following tetraploidy in maize, a short deletion mechanism removed genes preferentially from one of the two homeologs
MR Woodhouse, JC Schnable, BS Pedersen… - PLoS …, 2010 - journals.plos.org
Previous work in Arabidopsis showed that after an ancient tetraploidy event, genes were
preferentially removed from one of the two homeologs, a process known as fractionation …

Patterns and consequences of subgenome differentiation provide insights into the nature of paleopolyploidy in plants
Polyploidy is an important feature of plant genomes, but the nature of many polyploidization
events remains to be elucidated. Here, we demonstrate that the evolutionary fates of the …

Differentiation of the maize subgenomes by genome dominance and both ancient and ongoing gene loss
JC Schnable, NM Springer… - Proceedings of the …, 2011 - National Acad Sciences
Ancient tetraploidies are found throughout the eukaryotes. After duplication, one copy of
each duplicate gene pair tends to be lost (fractionate). For all studied tetraploidies, the loss …

Changes in twelve homoeologous genomic regions in soybean following three rounds of polyploidy
With the advent of high-throughput sequencing, the availability of genomic sequence for
comparative genomics is increasing exponentially. Numerous completed plant genome …

Following tetraploidy in an Arabidopsis ancestor, genes were removed preferentially from one homeolog leaving clusters enriched in dose-sensitive genes
BC Thomas, B Pedersen, M Freeling - Genome research, 2006 - genome.cshlp.org
Approximately 90% of Arabidopsis' unique gene content is found in syntenic blocks that
were formed during the most recent whole-genome duplication. Within these blocks, 28.6 …

Polyploidy and genome evolution in plants
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 …

Gene expression analysis at the intersection of ploidy and hybridity in maize
Heterosis and polyploidy are two important aspects of plant evolution. To examine these
issues, we conducted a global gene expression study of a maize ploidy series as well as a …

Persistence of subgenomes in paleopolyploid cotton after 60 my of evolution
The importance of whole-genome multiplication (WGM) in plant evolution has long been
recognized. In flowering plants, WGM is both ubiquitous and in many lineages cyclical, each …
