P. syringae pv. mori multiplied on leaf surface and colonized particularly on the cystoliths and in the grooves of veins. The masses of bacteria were associated with necrotic spots, which appeared 9 days after inoculation. The studies also revealed that the bacterium invaded leaf tissues through cystoliths. However, it did not enter through stomata and trichomes which had commonly been observed in most of the plant pathogenic bacteria.
