Where Do Phosphosites Come from and Where Do They Go after Gene Duplication?

Figure 3

Detailed analysis of the patterns of evolution of pSer and pThr sites. Each bar represents the percentage of sites (pSer, cSer, pThr, or cThr) that evolved from or to Asp or Glu. Numbers above the bars represent the total number of pSer, cSer, pThr, or cThr sites that were gained or lost. Numbers above the arrows indicate 𝑃-values of the Fisher’s exact tests, bold ones being below 0.05. The top panel shows results obtained by ancestral sequence reconstruction using a likelihood approach and the bottom panel using parsimony.
