DOIAbstract
Root colonization with arbuscular mycorrhizal fungi (AMF) improves plant tolerance against soil-borne pathogens. The purpose of the present study was to explore the efficacy of the AMF Rhizophagus intraradices (N.C. Schenck & G.S. Sm.) as a biocontrol agent against Fusarium pseudograminearum (O'Donnell and Aoki) in wheat plants grown under greenhouse conditions. Parameters here analyzed included disease severity, plant morphological features, mycorrhizal structures within roots, and oxidative stress levels. AMF inoculation significantly counteracted on the negative effects of the pathogen F. pseudograminearum on plant parameters such as aerial and root biomass, number of spikes and plant height. These results suggest that AMF inoculation co...
