Dercoreas reticulatum contains salicylic acids in its locomotion mucus.
LC-MS spectra of salicylic acid (left) and its internal standard (right) from locomotion mucus extracts from 13 different molluscan herbivores.
Figure 2.
Increased salicylic acid levels in extracts of Arabidopsis thaliana leaves supplied with locomotion mucus of Deroceras reticulatum.
Average ± SE of five biological replicates. Different letters indicate significant differences between treatments for each time point (ANOVA, Turkey HSD, P<0.05).
Figure 3.
Locomotion mucus of Deroceras reticulatum increases PR1 promotor activity in transgenic Arabidopsis thaliana PR1::GUS plants.
Leaves were wounded and water or D. reticulatum locomotion mucus was applied to wounds. Blue color indicates PR1 promotor activation. Pictures from two independent experiments are shown.
