Time course of consumption of linolenic (A) and linoleic (B) acids by LOX. The activities were monitored in control (dotted line) and P. putida BTP1-treated (continuous line) tomato leaves. Samples were collected before (0), two days (+2), and four days (+4) after inoculation of B. cinerea. Stars (*) indicate statistically significant differences between control and treated plants (Student's t test, α = 0,01). Data are means and standard deviations calculated from three measurements on two enzyme extracts.
