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 …

Pericentromeric effects shape the patterns of divergence, retention, and expression of duplicated genes in the paleopolyploid soybean
The evolutionary forces that govern the divergence and retention of duplicated genes in
polyploids are poorly understood. In this study, we first investigated the rates of …

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 …

Polyploidy and genome evolution in plants
Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

[HTML][HTML] Plant polyploidy: origin, evolution, and its influence on crop domestication
The prevalence and recurrence of polyploidization in plant species make it one of the most
important evolutionary events in plants, and as a result, polyploidization is an extensively …

Shared subgenome dominance following polyploidization explains grass genome evolutionary plasticity from a seven protochromosome ancestor with 16K …
Modern plant genomes are diploidized paleopolyploids. We revisited grass genome
paleohistory in response to the diploidization process through a detailed investigation of the …

[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 …

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 …

The fate of duplicated genes in a polyploid plant genome
Polyploidy is generally not tolerated in animals, but is widespread in plant genomes and
may result in extensive genetic redundancy. The fate of duplicated genes is poorly …
