Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of afamily member are provided. Recombinantfamily members expressing such fusion proteins are also provided. Genetically inactivatedfamily members and recombinantfamily members that overexpress exosporium proteins are also provided. Seeds coated with the recombinantfamily members and methods for using the recombinantfamily members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinantfamily members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

Fusion proteins, recombinant bacteria, and methods for using recombinant bacteria

Fusion proteins containing a targeting sequence, exosporium protein, or exosporium protein fragment that targets the fusion protein to the exosporium of a recombinantfamily member are provided. The fusion proteins further comprise an enzyme having ACC deaminase activity, a phospholipase, a lipase, a xylanase, a xylosidase, a lactonase, a chitosanase, a protease, a glucanase, a phytase, an acid phosphatase, a pectinase, a mannanase, and/or an expansin protein. Also provided are recombinantfamily members that express the fusion proteins, exosporium fragments derived from the recombinantfamily members, and formulations containing the recombinantfamily members or exosporium fragments. Plant seeds treated with the recombinantfamily members, exosporium fragments, or formulations are also provided. The invention further relates to methods for stimulating plant growth and/or promoting plant health using the recombinantfamily members, exosporium fragments, or formulations.
