relative expressions of proteases of D. magna grown in the presence or absence of microcystin. D. magna were grown on three different food treatments (100% S. obliquus, 10% M. aeruginosa PCC 7806 Mut and 90% S. obliquus, or on 10% M. aeruginosa PCC 7806 WT (with microcystins) and 90% S. obliquus). Depicted is the mean relative expression (n = 3, ± SD) of trypsins (T152, T208) or chymotrypsins (CT448, CT383, CT802). Letters indicate a significant difference (p < 0.05) between calibrator (S. obliquus) and cyanobacterial food treatments. The y-axis is scaled to 10 to allow comparison with Fig. 4.
