Figure 5From: Stability of toxin gene proportion in red-pigmented populations of the cyanobacterium Planktothrix during 29 years of re-oligotrophication of Lake ZürichComposition of the toxic and nontoxic genotype in populations of Planktothrix across Europe. Allelic discrimination plot of toxic and nontoxic Planktothrix genotypes of populations differing in pigmentation as determined by a custom TaqMan SNP genotyping assay within mcyT, indicative of a genotype that lost (allele 1) or still contains (allele 2) the mcy gene cluster. Delta Rn values represent the difference in fluorescence from the post-PCR and pre-PCR reads of the normalized reporter (VIC, FAM). The symbols represent the mean ± SE of measurements in triplicate. When not visible, the error bars are hidden behind the symbol. Values located close to the no-template control failed to amplify.Back to article page
