Table 1. Convergent-application biomarkers for mild stress induced enhanced robustness.
| Convergent-application biomarker multiple mild stresses, lethal stress specific | Mild stressa | Lethal stress |
| SigB | heat, salt | heat |
| ClpC | heat, acid | heat |
| ClpP | heat, acid | heat |
| clpC | acid, salt | acid |
| clpP | acid, salt | acid |
| catalase activity | heat, acid, H2O2 | H2O2 |
a
italic text indicates that mild stress treatment did not significantly induce the biomarker and also did not provide a robustness enhancement towards lethal stress upon pretreatment (no response condition).
