Clustering analysis of plants of ecotype Col-0 non-inoculated or inoculated with
. Fifteen plants of A. thaliana of ecotype Col-0 were inoculated with P. ramosa and 15 plants were not inoculated. The plants were imaged for 55 fluorescence parameters. Dendrograms were built based on the histograms of the CF parameter qP(25) using the WPGMA agglomeration method. Inoculated plants (red) and non-inoculated plants (blue) globally belong to different branches of the dendrogram. However, inoculated plants INOC-P9 and INOC-P3 group with non-inoculated plants. These plants are visually healthier than other inoculated plants, as seen on photo at the bottom of the figure. The non-inoculated plant Ctrl-P13 groups with inoculated plants. This plant is visually less healthy than other non-inoculated plants.
