The floral quartet model of floral organ specification poses that different tetramers of MIKC-
type MADS-domain transcription factors control gene expression and hence the identity of …

Highlights•Polyploidy or whole-genome duplication (WGD) is a ubiquitous feature of plant
genomes.•Polyploidy is most frequent in angiosperms.•A complex pattern of polyploidy is …

Wheat (Triticum aestivum) is one of the most important crops worldwide. Given a growing
global population coupled with increasingly challenging cultivation conditions, facilitating …

Tomato ripening is a highly coordinated developmental process that coincides with seed
maturation. Regulated expression of thousands of genes controls fruit softening as well as …

We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of
shotgun sequence assembly with genetic mapping enabled chromosome-scale …

Members of the MADS-box transcription factor family play essential roles in almost every
developmental process in plants. Many MADS-box genes have conserved functions across …

Many organisms are currently polyploid, or have a polyploid ancestry and now have
secondarily'diploidized'genomes. This finding is surprising because retained whole-genome …

Polyploidy has long been recognized as a major force in angiosperm evolution. Recent
genomic investigations not only indicate that polyploidy is ubiquitous among angiosperms …

Background Although it is agreed that a major polyploidy event, gamma, occurred within the
eudicots, the phylogenetic placement of the event remains unclear. Results To determine …

Genomic comparisons provide evidence for ancient genome-wide duplications in a diverse
array of animals and plants. We developed a birth–death model to identify evidence for …
