SUMMARY Arbuscular mycorrhizal (AM) fungi, which date from the Devonian era, must have dealt very early on with problems of plant defence, a tactic has enabled them to colonize roots most extant taxa. Conversely, plants forming arbuscular mycorrhiza exert some sort control over fungi during symbiotic interactions since mycelial proliferation within is confined cortical parenchyma tissue. Plants possess panoply defence mechanisms are triggered by microbial attack. Here we review present‐day knowledge defence‐related root responses colonization AM and assess their possible implications in symbiosis. Weak, transient, unco‐ordinated or extremely localized activation inducible occurs compatible differs that plant–pathogen interactions. When symbiosis‐related genes mutated, typical associated resulting resistance whilst, contrastingly, constitutively expressing unaffected capacities. The can modulate way A1V1 might contend these discussed.
