Figure 7

Time course of PT activity in wood and bark after treatment with MeJA. A, GPP synthase activity, wood. B, FPP synthase activity, wood. C, GGPP synthase activity, wood. D, GPP synthase activity, bark. E, FPP synthase activity, bark. F, GGPP synthase activity, bark. Values are the means of duplicate or triplicate assays of extracts from treated (●) and control (○) trees. A rapid increase of enzyme activity was found only for GGPP synthase in induced wood samples. The apparent increase in specific activities of GPP synthase and FPP synthase at d 35 reflect on a decrease of total protein in these samples. Ranges of duplicate assays were normally 1% to 25% of the mean but were 45% to 60% of the mean in control d 35 in A and B and in MeJA d 25 and 35 in B.
