Persistent PEI-SWNT specific gene response leads to severe leaf damage. A Arabidopsis leaves infiltrated with different PEI-SWNTs concentrations. Images taken two, four, six and eight dpi. B mRNA levels of selected marker genes at different time points after infiltration. mRNA levels are normalized to non-infiltrated samples at the corresponding time point (represented by a grey line). Each colored line represents the average mRNA levels at each time point and the faded band represents a 95% confidence interval (n = 3)
