TCV infection-caused temporal changes in rosette size and the percentage of unhealthy tissues in 10 single ago mutant plants. A, The growth curves show the temporal change of rosette area (total pixel number, averaged by four plants, ±se) in Col-0, dcl2 dcl3 dcl4, and 10 single ago mutant plants from 1 d preinoculation to 17 dpi (K-S test with α = 0.05, detailed D value, and P value are listed in Supplemental Table S1). B, The curves show the percentage of unhealthy tissue change overtime (red pixels/total pixels, averaged by four plants, ±se) in Col-0, dcl2 dcl3 dcl4, and 10 single ago mutant plants from 1 d preinoculation to 17 dpi. (K-S test with α = 0.05, detailed D value, and P value are listed in Supplemental Table S2). Curves with different letters are statistically different.
