Oxidative burst in Oryza sativa cell suspension culture.
ROS production was monitored over time after elicitation with products of chitin hexamer (A6) PesCDA incubation (a). Mean of maximal ROS production; the standard deviation was calculated based on three independent experiments (b). t1 to t4 refer to different time points of enzyme incubation (see Table 1); A6* was incubated with heat-deactivated enzyme; D6 chitosan hexamer.
