Figure 3. Flight response of C. glomerata to Arabidopsis wt plants that had been previously exposed to hpl1 volatiles under different conditions.

Undamaged wt-[damaged hpl1]: undamaged wt receiver plants exposed to volatiles from damaged hpl1 emitters; Undamaged wt-[undamaged hpl1]: undamaged wt receiver plants exposed to volatiles from undamaged hpl1 emitters; Damaged wt-[damaged hpl1]: damaged wt receiver plants exposed to volatiles from damaged hpl1 emitters; Damaged wt-[undamaged hpl1]: undamaged wt receiver plants exposed to volatiles from undamaged hpl1 emitters. Choice data were analysed with a binomial test (α = 0.05).
