The Arbuscular mycorrhizal fungi (AMF) (Funneliformis mosseae), are the most widely distributed symbiont assisting plants to overcome counteractive environmental conditions. In order improve sustainability and activity of AMF, use nanotechnology was important. main objective this study investigate effect titanium dioxide nanoparticles (TiO2NPs) on AMF in common bean roots as well its under salinity stress using morphological molecular methods. colonization has increased presence TiO2NPs especially for arbuscule (A%), which three times with TiO2NPs. improvement rate Funneliformis mosseae plant growth from 180% 224% control at lowest level 48% 130% higher level, respectively. dependencies dry biomass 277% absence 465 883% % low high levels, co-inoculated resulted increasing tolerance all levels reached 110% 100 mM NaCl. Quantitative methods showed that intensity ratio relative density paired inocula Nest (NS) or chitin synthases gene (Chs) were significantly P.>0.05 than single inoculants by about two folds 40%. Hence, positive confined not itself.
