Figure 5. Habituation of CTKR and CTKRs evoked through substrate vibrations.

Figure 5

Quickly moving back and forth the tip of a blue ball pen (see S1A) resulted in a habituation of CTKR of A. nerii (A) and U. hypochoeridis (B) colonies. Stimulus directions are indicated by double-arrows in the pictures next to A and B. The stimulus in A was either presented from the right side (blue curve) or from top (red curve). Introducing a pause of 15 s in A. nerii (last dot in the red curve in A) and a pause of 60 s in U. hypochoeridis restored CTKR (red curve in B). C Time course of CTKR evoked by substrate vibrations that were induced by gently tipping on the stalk 10 cm below the colonized leaf (ellipse in the picture next to C). Vibratory stimulations were separated by pauses of 30 s. Curves in C are aligned to the onset of the stimulus.
