Fold changes of expression of metal-responsive core transcriptome at HD^a

^aThe change in expression was considered statistically significant if the fold change in expression in response to the metal compared with that of the control was ≥2.0-fold and the P value was ≤1.0E−4. PFOR, pyruvate ferredoxin oxidoreductase; sub, subunit; †, also responsive at the LD; #, responsive only at the LD; gray shading, no statistically significant response observed; ^, least-squares mean (LSM), for which a value of 0 is the average transcription level for all ORFs. Violet, white, and green correspond to above average, average, and below average levels of transcription, respectively. Fold change was calculated as 2^{(LSM_metal−LSM_control)}.
