Studying gene expression in polyploids is complicated by genomewide gene duplication
and the problem of distinguishing transcript pools derived from each of the two …

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 …

INTRODUCTION Polyploidy, arising from whole-genome duplication or interspecific
hybridization, is ubiquitous across the plant and fungal kingdoms. The presence of highly …

Since the discovery of polyploidy (the presence of more than two chromosome sets in a
nucleus) a century ago, scientists have investigated and speculated about the factors that …

A phylogenetic tree can be used to illustrate the evolutionary relationship between a group
of genes, especially duplicated genes, which are sources of genetic innovation and are …

Polyploidy appears dependent on heterozygosity! The largest group of polyploids, the
allopolyploids (disomic polyploids), have fixed heterozygosity in the two or more divergent …

Abstract.—Experimental advanced‐generation backcross populations contain individuals
with genomic compositions similar to those resulting from interspecific hybridization in …

Genome sizes vary by several orders of magnitude, driven by mechanisms such as
illegitimate recombination and transposable element proliferation. Prior analysis of the CesA …

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 …

Background Intergenomic gene transfer (IGT) between nuclear and organellar genomes is a
common phenomenon during plant evolution. Gossypium is a useful model to evaluate the …
