• The histological reaction of current shoots of the Japanese cedar. Cryptomeria japonica, inoculated with Cercospora sequoiae was investigated. Wound periderm was formed on current shoots of the cedar on and after the 4th day after inoculation. In the cells of the cork layer, lignin and suberin were deposited, and a phenolic substance was accumulated. In other inoculated samples, plasmolysis, contraction of the cells and necrosis of the tissues were also observed. On the 32nd day, wound periderm and phellogen were observed in samples of the tissue inside the necrotic tissues in response to hyphal invasion. Occurrence of wound periderm and phellogen in tissues of the needles was confirmed in the inoculated samples although no hyphae were observed in and around the tissues. These results suggest that this fungus causes necrosis of host tissues and induces defense responses.
