The subject matter disclosed herein pertains to the modulation of a bacterial invasion switch and the subsequent use of the bacterium to vaccinate an organism. In one embodiment, the bacterial invasion switch is modulated by changing the proteolysis of ExoR protein. In another embodiment, a mutated bacterium produces a mutant ExoR protein that resists proteolysis.

The present invention relates to an endophyte strain isolated from a plant of the Poaceae family, wherein said endophyte is a strain of Pseudomonas poae which provides bioprotection and/or biofertilizer phenotypes to plants into which it is inoculated. The present invention also relates to plants infected with the endophyte and related methods.
