Figure 3. Ordination analysis of genetic divergence data ( weighted per-gene F ST). The points are individual genes, the vectors are original contrasts (see legend). The two labeled red points are genes sharing strong genetic divergence in both high-CO2 adaptation datasets; GPX4 stands for glutathione peroxidase 4. Bar chart displays the proportion of variance explained by each principal coordinate.
Figure 4. Gene set overlap analysis for the top 25% quantiles of F ST datasets. Bar chart displays the number of outlier genes shared between contrasts identified by connected dots below; the first five bars are numbers of contrast-specific outlier genes.
