Polyploidy is a major evolutionary force that has shaped plant diversity. However, the
various pathways toward polyploid formation and interploidy gene flow remain poorly …

Whole genome duplications (WGDs) have played a major role in angiosperm species
evolution. Polyploid plants have undergone multiple cycles of ancient WGD events during …

Interspecific hybridization and allopolyploidization contribute to the origin of many important
crops. Synthetic Brassica is a widely used model for the study of genetic recombination and …

Background Allopolyploids require rapid genetic and epigenetic modifications to reconcile
two or more sets of divergent genomes. To better understand the fate of duplicate genes …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms …

Allohexaploid Brassica hybrids (2 n= AABBCC) have been the subject of plant breeding and
research for many years, both to increase our understanding of polyploid plant evolution and …

Production of allohexaploid Brassica (2 n= AABBCC) is a promising goal for plant breeders
due to the potential for hybrid heterosis and useful allelic contributions from all three of the …

Allopolyploidy, which results from the merger and duplication of two divergent genomes, has
played a major role in the evolution and diversification of flowering plants. The genomic …

Allopolyploid species contain more than two sets of related chromosomes (homoeologs) that
must be sorted during meiosis to ensure fertility. As polyploid species usually have multiple …

Homoeologous recombination, aneuploidy, and other genetic changes are common in
resynthesized allopolyploid Brassica napus. In contrast, the chromosomes of cultivars have …
