… Allopolyploidy is a prominent mode of speciation in higher plants. Due to the coexistence of
closely related genomes, a successful allopolyploid … and synthetic allopolyploids have raised …

… a key role in the evolution of the three most important crops, wheat, maize and rice, each of
which provides a unique model system to study allopolyploidy, segmental allopolyploidy, or …

… nonrandom elimination of DNA sequences augments the divergence of homoeologous
chromosomes, that is, it accelerates the evolution of genomic allopolyploids from segmental …

… allopolyploidy accelerates genome evolution in wheat in two ways: (1) allopolyploidization
triggers rapid genome … sporadic genomic changes during the life of the species (evolutionary …
