N2 - A hypersensitive response (HR) occurs after infection of cotyledon, leaf and stem of Brassica napus cv. Surpass 400 by an avirulent strain of Leptosphaeria maculans. The cotyledon or the sixth true-leaf stages of plants were inoculated with pycnidiospores of L. maculans (strain UWA P11). For the first time in this specific pathosystem and its HR, we report condensation of cytoplasm, shrinkage in cell size and nuclear DNA fragmentation in cotyledon tissues, and in stem tissues, shrinkage and condensation of the cytoplasm, chromatin fragmentation and lobing of the nucleus.
