FIGURE 4.

Expression analysis of marker genes for JA (A,B), ABA (C,D), IAA (E,F), and GA (G,H) in the sixth leaf of mock control (CW, CB, and CS), blast-infected (BW, BB, and BS), and cutting off blast-infected leaf blades (BcW, BcB, and BcS). Rice seedlings at four-leaf stage were blast-inoculated, and half of them were subjected to cutting off the inoculated fourth leaf blades at 2-dpi. Whole sixth leaf from every treatment was collected at 3-dpi (CW, BW, and BcW), and leaf blades (CB, BB, and BcB) and leaf sheathes (CS, BS, and BcS) separately at 6-dpi. Values are the means ± standard errors. Different letters above bars indicate a significant difference (P < 0.05) based on Duncan’s test; (w): for whole leaves, (b): for leaf blades, (s): for leaf sheaths.
