Is a Fully Established Arbuscular Mycorrhizal Symbiosis Required for Bioprotection of <i>Pisum sativum</i> Roots against <i>Aphanomyces euteiches</i>?

Abstract

Bioprotection of pea roots against Aphanomyces euteiches by the arbuscular mycorrhizal fungus G. mosseae was demonstrated to depend on a fully established symbiosis. This was related with induction of mycorrrhiza-related chitinolytic enzymes. Possible mechanisms implicated in bioprotection are discussed.
