Functions and stress responsiveness of retained duplicates in the C. reinhardtii lineage. (A) Functions of retained duplicates. Columns indicate four phylogenetic branches as in Figure 2 with the most recent on the far right. Rows indicate GO biological processes terms with over or under-represented numbers of retained duplicate genes in at least one branch. Values shown are -log₁₀(p) for over-represented and log₁₀(p) for under-represented categories, respectively. (B) Stress responsiveness of retained duplicates. Stress conditions shown are N (nitrogen deprivation), S (sulfur deprivation), Cu (copper deprivation), Fe (iron deprivation), CO2 (CO₂ deprivation), oxidative (oxidative stress), and all (all six conditions combined). Values shown are -log₁₀(p) for over-representation and log₁₀(p) for under-representation. Branches are the same as (A).
