GO slim analysis of fast evolving genes. A. Frequency of GO-slim terms. The x-axis represents GO-slim terms classified into the biological process (BP), cellular component (CC) and molecular function (MF) while the y-axis represents % of fast evolving genes assigned to specific GO-slim categories. B. GO-slim enrichment analysed by fisher’s exact test and p-values estimating fisher’s exact test under the description. The x-axis represents fold ratio between the frequency of fast evolving gene in recent or young genome categorized in certain GO-slim terms and background frequency (total B. rapa gene are not detected in fast evolving genes) in that term. The y-axis represents GO-slim terms. Different levels of p-value (< 0.05, < 0.01, < 0.001) are represented by *, **, ***, respectively.
