TCV infection-caused temporal color changes in control plants. A and B, The histogram illustrates the temporal changes (1 d preinoculation to 17 dpi, from bottom to above) of pixel distribution at each hue value (degree) in Col-0 (A) and dcl2 dcl3 dcl4 (B) plant rosette images. Pixels were collected and summed up from four individual images in the same treatment group: mock (left), TCV (middle), or TCV CPB (right) inoculum. The color chart illustrates the relationship between the hue value (degree) with the corresponding RGB coordinates. C and D, The plots show the average hue value (degree) change over time (averaged by four plants, ±se) in Col-0 (C) and dcl2 dcl3 dcl4 (D) plants from 1 d preinoculation to 17 dpi (K-S test with α = 0.05). E, The box plot shows the average hue value at 17 dpi in Col-0 and dcl2 dcl3 dcl4 plants. Statistical analysis was calculated between treatments in each genotype. Boxes with different letters are statistically different (n = 4, Tukey post hoc test with α = 0.05).
