Top 10 highest correlating transcript levels with robustness towards heat stress (A) or oxidative stress (B). Average P-value is the average of the P-values of the correlation as assessed by a linear model of the strains MG1363, IL1403, KF147 and SK11 and was used to rank the genes. Maximum P-value indicates the largest P-value of the correlation among the four strains.
