ABSTRACT
The use of arbuscular mycorrhizal (AM) fungi has great potential, being used as biostimulants, biofertilizers and bioprotection agents in agricultural natural ecosystems. However, the application AM fungal inoculants is still challenging due to variability results when applied production systems. This partly differences symbiosis establishment. Reducing such promoting establishment essential improve efficiency inoculants. In addition strigolactones, flavonoids have been proposed participate pre-symbiotic plant-AM fungus communication rhizosphere, although their role unclear. Here, we studied specific function signaling molecules symbiosis. For that, both vitro planta approaches were test stimulatory effect an array different subclasses on Rhizophagus irregularis spore germination establishment, using physiological doses compounds. We show that flavone chrysin flavonols quercetin rutin able promote root colonization at low doses, confirming pave way these formulation fungal-based products can commercial inoculants, therefore, help implement sustainable agriculture.
