Fig. 6: Mechanosensory trichomes evoke an immune response.

From: Mechanosensory trichome cells evoke a mechanical stimuli–induced immune response in Arabidopsis thaliana

Fig. 6

Model showing how trichomes directly sense the mechanical impact of raindrops as an emergency signal in anticipation of possible infections. Mechanosensory trichome cells initiate intercellular calcium waves in response to MS. [Ca2+]cyt initiates the de-repression of Ca2+/CaM-dependent CAMTA3 and activates the phosphorylation of MPK3 and MPK6, thereby inducing WRKY-dependent transcription.
