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.
