Cd and Zn concentration in <i>Δycf1</i> and <i>Δzrc1</i> yeast cells expressing <i>SaMT2</i>.

<p>The yeast transformants containing pDR195 or pDR195-<i>SaMT2</i> were grown in liquid SD selective medium with 30 µM CdCl₂ and 100 µM ZnSO₄ for <i>Δycf1 and </i><i>Δzrc1</i>, respectively. Cells were incubated at 30°C for 48 h and metal contents were measured by ICP-MS. Results are averages (±S.E.) from three independent experiments done with four different colonies. The ‘*’ symbol indicates the mean values were significantly different at p<0.05 (Tukey’s test).</p

Cd and Zn tolerance of yeast cells expressing <i>SaMT2</i>.

<p>The <i>Saccharomyces cerevisiae</i> BY4741, <i>Δycf1</i> and <i>Δzrc1</i> yeast cells harboring pDR195 (vector control) or pDR195-<i>SaMT2</i> were grown in liquid SD selective medium. Cultures were adjusted to OD_600nm of 0.1 and serially 10-fold diluted in water. 10 µl aliquots of each dilution were spotted either on SD selective plates or on plates with 30 µM CdCl₂ or 5 mM ZnSO₄. After 3 days of incubation at 30°C, plates were photographed. CK represents the control group.</p

The expression level of <i>SaMT2</i> in <i>Sedum alfredii</i>.

<p>The transcript level of <i>SaMT2</i> induced by Cd and Zn treatments. The different letters above the columns indicate the significant difference between the treatments (p<0.05, Tukey’s test). CK represents the control group.</p
