Fig. 5From: Assessing the effects of accumulated Cd(II) on seed germination and root development of Arabidopsis thalianaStandard curve for quantifying the accumulated Cd(II) concentration in plants. The known Cd(II) concentration of ranging from 0 to 0.1 mg/L was spiked to E. coli-cell based biosensor and the induction coefficient values were determined after 1 h of exposure. The induction coefficient values were plotted against the Cd(II) concentration and the equation was obtained by a hyperbolic curve fit with R2 = 0.995Back to article page
