Autopolyploids of Arabidopsis thaliana are more phenotypically plastic than their diploid progenitors.

ABSTRACT:

Background and aims

Polyploids are often hypothesized to have increased phenotypic plasticity compared with their diploid progenitors, but recent work suggests that the relationship between whole-genome duplication (WGD) and plasticity is not so straightforward. Impacts of WGD on plasticity are moderated by other evolutionary processes in nature, which has impeded generalizations regarding the effects of WGD alone. We assessed shifts in phenotypic plasticity and mean trait values accompanying WGD, as well as the adaptive consequences of these shifts.

Methods

To isolate WGD effects, we compared two diploid lineages of Arabidopsis thaliana wiht corresponding autotetraploids grown across different salt and nutrient conditions in a growth chamber.
