Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

Background The growing wealth of knowledge on whole-plant genome sequences is
highlighting the key role of transposable elements (TEs) in plant evolution, as a driver of …

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

Allopolyploidy involves hybridization and duplication of divergent parental genomes and
provides new avenues for gene expression. The expression levels of duplicated genes in …

Background In studies looking at individual polyploid species, the most common patterns of
genomic change are that either genome size in the polyploid is additive (ie the sum of …

Transposable elements (TEs) represent an important fraction of plant genomes and are
likely to play a pivotal role in fuelling genome reorganization and functional changes …

Here, we describe the evolution of gene expression among a diversified cohort of five
allopolyploid species in the cotton genus (Gossypium). Using this phylogenetic framework …

Polyploidy is an important force in the evolution of flowering plants. Genomic merger and
doubling induce an extensive array of genomic effects, including immediate and long-term …

Phylogenetic utility of two nuclear genes (GBSSI-2 and DHAR) was explored in genus
Fragaria in order to clarify phylogenetic relationships among taxa and to elucidate the origin …

Transposable elements, particularly LTR-retrotransposons, comprise the primary vehicle for
genome size expansion in plants, while DNA removal through illegitimate recombination …
