Genomic architecture of adaptive radiation and hybridization in Alpine whitefish
Adaptive radiations represent some of the most remarkable explosions of diversification
across the tree of life. However, the constraints to rapid diversification and how they are …

Subgenome dominance in an interspecific hybrid, synthetic allopolyploid, and a 140-year-old naturally established neo-allopolyploid monkeyflower
Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

The long and short of doubling down: polyploidy, epigenetics, and the temporal dynamics of genome fractionation
We consider the rapidly advancing discipline of plant evolutionary genomics, with a focus on
the evolution of polyploid genomes. In many lineages, polyploidy is followed by 'biased …

The ancient wave of polyploidization events in flowering plants and their facilitated adaptation to environmental stress
Flowering plants, or angiosperms, consist of more than 300,000 species, far more than any
other land plant lineages. The accumulated evidence indicates that multiple ancient …

Extraordinary preservation of gene collinearity over three hundred million years revealed in homosporous lycophytes
Homosporous lycophytes (Lycopodiaceae) are a deeply diverged lineage in the plant tree of
life, having split from heterosporous lycophytes (Selaginella and Isoetes)~ 400 Mya …

Patterns, mechanisms, and consequences of homoeologous exchange in allopolyploid angiosperms: a genomic and epigenomic perspective
Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …
