The present invention is generally directed to fusion proteins containing a targeting sequence that targets the fusion protein to the exosporium of a Bacillus cereus family member. The invention also relates to recombinant Bacillus cereus family members expressing such fusion proteins, formulations containing the recombinant Bacillus cereus family members expressing the fusion proteins. Methods for stimulating plant growth and for protecting plants from pathogens by applying the recombinant Bacillus cereus family members or the formulations to plants or a plant growth medium are also described. The invention also relates to methods for immobilizing spores of a recombinant Bacillus cereus family member expressing a fusion protein on plant roots.
