Ancient duplication events and a high rate of retention of extant pairs of duplicate genes
have contributed to an abundance of duplicate genes in plant genomes. These duplicates …

Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

An ordered draft sequence of the 17-gigabase hexaploid bread wheat (Triticum aestivum)
genome has been produced by sequencing isolated chromosome arms. We have annotated …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Different plant species within the grasses were parallel targets of domestication, giving rise
to crops with distinct evolutionary histories and traits. Key traits that distinguish these species …

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

Duplication is a prominent feature of plant genomic architecture. This has led many
researchers to speculate that gene duplication may have played an important role in the …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Allohexaploid bread wheat (Triticum aestivum L.) provides approximately 20% of calories
consumed by humans. Lack of genome sequence for the three homeologous and highly …

The wheat group has evolved through allopolyploidization, namely, through hybridization
among species from the plant genera Aegilops and Triticum followed by genome doubling …
