稻瘟病病菌（Magnaporthe grisea）分生孢子悬浮液具有激发子活性，可诱导水稻细胞中防御相关基因的表达和H2O2的产生。产生的H2O2水平依赖于真菌分离株，并与每个分生孢子悬浮液上清部分的过氧化氢酶活性相关，而与基因对基因的相互作用无关。
A conidia suspension of Magnaporthe grisea carried elicitor activity that induced the expression of defense-related genes and the production of H2O2 in suspension-cultured rice cells. The levels of H2O2 produced were dependent on fungal isolates and were correlated with the catalase activity in the supernatant fraction of each conidia suspension, not with gene-for-gene interactions.
