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 …

Preferential retention of genes from one parental genome after polyploidy illustrates the nature and scope of the genomic conflicts induced by hybridization
Polyploidy is increasingly seen as a driver of both evolutionary innovation and ecological
success. One source of polyploid organisms' successes may be their origins in the merging …
