Decrease in PCB congeners caused by planting nettles in the contaminated soil from Lhenice.
Standard errors are expressed as a standard deviation depending on the square root of the number of replicas [56]. The decrease in individual congeners was determined as the variance between the congener amount in the planted soil and non-planted soil (expressed in %, relative to 1 g of nettles). The data were analyzed using Fisher's Least Significant Difference (LSD) test at 5% probability level.

Detection of transgene expression at mRNA level in transiently transformed nettles.
The transgenes used, CUP (left) and bphC (right), originate from microorganisms, where they play an important role in remediation and tolerance to pollutants.
