relative gene expressions of proteases of D. magna grown on different food treatments. D. magna were grown on three different food treatments (100% S. obliquus, 20% M. aeruginosa NIVA Cya 43 (with chymotrypsin inhibitors) and 80% S. obliquus or on 20% M. aeruginosa PCC 7806 Mut (with trypsin inhibitors) and 80% 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.
