Figure 6.

Relative normalized expression of the target genes GapDH (top), UBC (middle) and SucDH (bottom) in Daphnia magna in the microcystin experiment. D. magna was raised either on the green alga S. obliquus (= calibrator set at 1), on microcystin-free cyanobacteria (S. elongatus or the mutant of M. aeruginosa PCC 7806), or on the microcystin-producing M. aeruginosa PCC 7806 wild type. Depicted is the mean relative expression (n = 3, ± SD) of GapDH, UBC and SucDH. Letters indicate a significant difference (p < 0.001) between treatments.
