摘要
Interactions between an arbuscular mycorrhizal fungus and pea cv. Frisson (myc(+)) or an isogenic mycorrhiza-resistant mutant (myc) were investigated by immunocytochemistry. Observations of the presence of proteins and polysaccharides accumulating in other symbioses (pectins) or in plant-pathogenic interactions (PR-b(1) protein, beta-1,3-glucans) indicated a weak activation of defence mechanisms during establishment of symbiosis. In contrast, the myc(-) mutant showed an important defence reaction against the mycorrhizal fungus, suggesting that there are complex interactions between defence genes and symbiosis genes during endomycorrhiza establishment.
