Abstract: In a greenhouse experiment, was adapted to monitor potential of faba bean seed bacterization with R. leguminosarum for induction of systemic resistance in faba bean against Broad bean mottle virus and Botrytis fabae. The results demonstrated that BbMV or/and B. fabae challenged plants emerged from R. legumonisarum inoculated seeds not only showed a pronounced reduction in percent disease severity but also reduction in virus concentration and B. fabae count compared to the non-bacterized ones. The bioproduct efficiency to restrict the pathogenicity of BbMV and B. fabae hardly exceeded 49.85 and 77.50% with seed bacterilization respectively. In parallel with disease reductions, the faba bean plant survival was the best (average of 71.0%) when Rhizo-N was seed bacterized system. Appreciable the significant increase in both salicylic acid level, chlorophyll content, protein and peroxidase activity were recorded in leaves of all PGPR (plant growth promoting rhizobacteria) inoculated plants compared to non-bacterized ones. At harvest, the tallest of nodulated plants (45.3 cm) were those received the bioagent Rhizo-N infected faba bean host 38.5 and 35.7 cm of BYMV and B. fabae. As well as 25,15 and 14 nodules -like structures per plant on their root system, respectively. On the other hand, BbMV and B. fabae induced systemic acquired resistant in faba bean plants against pathogens. Whereas mixed infection due to reduction of BbMV (49.85%) or B. fabae (49.80%) infection. It was increased by seed bacterization with 64.30% for BbMV and B. fabae. The nodulatedfaba bean plants; BYMV and B.fabae infected ones were varied in number and density of expressed protein bands. The polymorphic (specific bands) with 52.1% polymorphism, monomorphic (commonly bands) was percentage 34.2%. and the unique band (genetic markers) was percentage 13.8% related to 1 in Rhizobium(R), BYMV(V); 2 in B. fabae(B), R+V; 3 in R+B,V+B and 4 in R+V+B with MW 70 to 14 KDa.
