Abstract: Plants have evolved adaptive responses to a wide range of mechanical stimuli, such as gentle touch caused by light wind. Although touch-induced responses have been shown to share signaling components with defense pathways, whether the phyllosphere microbiota contributes to touch-triggered disease resistance remains unknown. Herein, we demonstrated that touch-induced resistance against Botrytis cinerea in tomato leaves is partially dependent on the phyllosphere microbiome, as surface sterilization significantly diminished the protective effect of touch. Using 16S ribosomal RNA (rRNA) amplicon sequencing, we found that repeated gentle touch markedly restructures the phyllosphere bacterial community. Screening against probiotic databases revealed that the majority of the enriched beneficial taxa belonged to the genus Pseudomonas. We further conducted plate confrontation assays to isolate seven Pseudomonas strains that exhibited antagonistic activity against B. cinerea. A synthetic community reconstituted from these isolates significantly reduced lesion development when applied to tomato leaves prior to B. cinerea inoculation. Our findings suggest that mechanical stimulation might enrich beneficial Pseudomonas populations in the phyllosphere, revealing a previously unrecognized link between mechanical stimuli and the plant microbiome.
