Figure 2. Flight response of C. glomerata to Arabidopsis wt plants that had been previously exposed to wt volatiles under different conditions.

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