When everything changes at once: finding a new normal after genome duplication
Genome duplication results in substantial changes to the cell biology and physiology of plants. One of the most common changes in neopolyploids is an increase in cell size. This has important implications for growth, fitness and stress resilience in neopolyploids. But is an increase in cell size a challenge or an opportunity? This literature review suggests that probably both are true, and discusses how polyploids can evolve a “new normal” through extensive physiological retuning.
