Parental squabbles and genome expression: lessons from the polyploids.
The merger of evolutionarily diverged genomes to form a new polyploid genetic system can involve extensive remodeling of gene regulation. A recent paper in BMC Biology provides important insights into regulatory events that have affected the evolution of allopolyploid cotton.
