Histological observation and measurement of infection hyphal during the incompatible interaction between Suwon11 and CYR23.

xControl, leaves treated with Fes buffer; BSMV:00, leaves treated with BSMV genome with insert; BSMV:TaAbc1, leaves treated with BSMV carrying a fragment of TaAbc1; ymean of values (numbers) ± standard deviation of the hyphal length per colony (unit in 100 µm); zarea of dead mesophyll cells around an infection site (unit in 1000 µm2, length × width of individual dead spots); a: indicates insignificant difference; b: indicates significant difference at PP
