relative gene expressions of proteases of D. magna grown on different food treatments after 24 and 48 h. Relative gene expression of proteases form D. magna grown on 100% S. obliquus for 24 h or 48 h ("24 h S.obliquus" or "48 h S.obliquus"), or grown on 20% M. aeruginosa (with chymotrypsin inhibitors) NIVA CYA 43 and 80% S. obliquus for 24 h ("24 h NIVA"), or for another 24 h on 100% S. obliquus ("24 h NIVA + 24 h 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 (24 h S. obliquus) and cyanobacterial food treatments.
