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

We summarize, in this review, the evidence that genomic balance influences gene
expression, quantitative traits, dosage compensation, aneuploid syndromes, population …

Cultivated strawberry emerged from the hybridization of two wild octoploid species, both
descendants from the merger of four diploid progenitor species into a single nucleus more …

Gene duplications have long been recognized as a contributor to the evolution of genes with
new functions. Multiple copies of genes can result from tandem duplication, from …

The evolution of land flora transformed the terrestrial environment. Land plants evolved from
an ancestral charophycean alga from which they inherited developmental, biochemical, and …

Heterosis refers to the phenomenon that progeny of diverse varieties of a species or crosses
between species exhibit greater biomass, speed of development, and fertility than both …

Each mode of gene duplication (tandem, tetraploid, segmental, transpositional) retains
genes in a biased manner. A reciprocal relationship exists between plant genes retained …

Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …

Differences between males and females in the optimal phenotype that is favoured by
selection can be resolved by the evolution of differential gene expression in the two sexes …

To study the evolutionary effects of polyploidy on plant gene functions, we analyzed
functional genomics data for a large number of duplicated gene pairs formed by ancient …
