P. parasitica gene expression patterns in response to I-1G6-GFP. Roots of 2-week-old plants covered with a P. parasitica biofilm after 3 h of incubation with zoospores. They were then incubated in water or in the presence of I-1G6-GFP. mRNAs relative abundance were measured by RT-qPCR at 2, 6, and 20 h post-bacterial inoculation and for PPMUCL1, PPMUCL2, PPMUCL3 (a), PPTG03562, PPTG02949, PPTG4818 (b) and PSE1 (c). A Student’s t test indicated no significant differences between mock and inoculated situations (0.06 < p < 0.92, n = 3) except at 2 dpi for PPMUCL1, PPMUCL2, and PPTG4818 (p = 0.01, 0.02, and 0.04, respectively)
