Fig. 5

The plots of predicted models for oxygenated taxanes, biomass accumulation and ROS level in BN6 strain expressing Taxus cuspidata CYP725A4 and reductase in tandem. A Effect plots showing the regression-based fitted values for each response relative to the concentrations of the predictors when supplemented in the growth medium (unit: mM for all predictors, except for hemin: µM); B Correlation plot for variables, showing the correlation coefficients between all the screened factors (navy blue and maroon represent the strongest positive and negative associations, respectively). The asterisks indicate significant differences in each pair of correlations (***p < 0.001, **p < 0.01, *p < 0.05). T5alphaOl and iso.OCT represent T5α-ol and iso-OCT.
