From: RNA silencing can explain chlorotic infection patterns on plant leaves
Infection patterns caused by RNA silencing. (A-C): low silencing strength (Dicer cleavage rate is 5 cleavages per Dicer per hour). (A) concentric circles, (B) mosaic and (C) local spot. (D-G): intermediate silencing strength (Dicer cleavage rate is 15 cleavages per Dicer per hour). (D) speckle-pattern; (E) concentric circles; (F) mosaic; and (G) local spot. The patterns spread over the entire tissue, except the patterns shown in C and G. In the first three columns the number of +RNAs is shown for 75, 150 and 300 hours post infection (hpi), column 4 and 5 show siRNA and virions, respectively. Also shown is the intracellular amount of +RNA through time for a row of cells. ΔSi gives the percentage of siRNAs that move to neighboring cells per hour. Colors according to the color-ramps shown in Figure 2.
