Living and heat-killed bacterial cells of Rhizobium leguminosarum protected totally lentil plants against infection by the pathogen Fusarium oxysporum MR 84. Culture filtrate of this rhizobacterium was also able to protect the plants to a high degree. However, when they were inoculated separately of the pathogen, living bacterial cells did not protect the plants whereas culture filtrate and killed bacterial cells protected them. These results suggest that Rhizobium cannot protect lentil plants without interaction with the pathogen, but the culture filtrate and the killed bacterial cells can protect them even in the absence of this interaction. It seems that the culture filtrate and the killed bacterial cells contain signals able to induce plant resistance. Those signals would be suppressed once Rhizobium is in contact with the plant.
