What does the published scientific research say about Rhizophagus intraradices?

Peer-reviewed research characterizes R. irregularis as the model species for AMF study and the most widely propagated for commercial plant biostimulants. Literature cited across these records covers tobacco growth promotion, mine-site revegetation, and biostimulant, biofertilizer, and bioprotection applications. One study identified the flavonoids chrysin, quercetin, and rutin as pre-symbiotic signaling molecules that promoted spore germination and root colonization in R. irregularis — a finding the authors proposed could improve inoculant formulation efficiency.

A greenhouse study (PMID 32853027) reported that R. intraradices inoculation improved both plant growth and lead uptake in Parkinsonia aculeata under elevated lead concentrations, a result the authors described as relevant to phytoremediation research. A mine-wasteland review (PMID 39035525) separately cited R. irregularis as enhancing plant growth and survival in revegetated mine sites.
