Fig 6. Relative fold-induction of the five T. thermophila MT genes in metal-adapted strains.

Fig 6

These strains were maintained for 1 or 6 months without the metal treatment and then re-exposed (1 or 24h) to the relevant MTC. (A): Cd-adap after 1 month without metal (-1M). (B): Cd-adap after 6 months without metal (-6M). (C): Cu-adap (-1M). (D): Cu-adap (-6M). (E): Pb-adap (-1M). (F): Pb-adap (-6M). β-actin was used as the normalizer gene. Each histogram bar represents an average value ± standard deviation (see S3 Table) from two or three independent experiments. Asterisks indicate significant differences from the control with p ≤ 0.05.
