Experimental evolution in plants: how to adapt to climate change? One effect of climate change is that plants are exposed to increasing local variation in weather conditions, including more episodes of heat stress. Should plants evolve to perform better at high temperatures, or to become more plastic and cope with a broader range of temperatures? This project compares duckweed genotypes with different levels of plasticity in gene expression, and uses experimental evolution and genomic analysis to test if more plastic genotypes have a selective advantage when temperature environments become more variable.
