Experimental evolution of TuMV lineages. (A) Experimental design of the evolution experiment. (B) AUDPS measured at the beginning and after five passages of experimental evolution for viruses evolved in standard (Upper) and in drought conditions (Lower) for each one of the A. thaliana accessions (columns). Significance values from pairwise post hoc Bonferroni tests in the GLM described in Eq. 1; in all cases, P ≤ 0.004. (C) Mutations found in the standard- (Left) and drought-evolved (Right) lineages. Each square corresponds with a protein indicated in the lowest row (proportional to the cistron size). Nonsynonymous mutations are indicated with the new amino acid in red.
