Leaf samples were collected 0 (pre-inoculation), 24, 48, 72, 48, 72, 96 and 120Â h after inoculation of Rs and activity of PPO (a) and PAL (b) was measured. Error bars indicate the standard deviation from the mean. Each experiment was performed with five replicates, and the experiment was repeated three timesBack to article page
