The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Treatment with flg22 peptide is sufficient to increase filament density.
Twenty-four d-old plants that were hand-infiltrated with 1 µM flg22 peptide show significantly enhanced filament density (A), whereas the same concentration of either elf26 or A. tumefaciens flg (flgAt) peptide exhibit no change compared to mock controls. Bundling analysis (B) of the same images used in (A) shows no significant change for any MAMP peptide treatment. Epidermal pavement cells from rosette leaves were imaged by SDCM at 0–3 hpi and 24 optical sections were combined into a z-series projection. Values given are means ± SE (n = 150 images per treatment, from n = 3 biological repeats). Asterisks represent significant differences by ANOVA.
