Methods for stimulating plant growth and/or promoting plant health using free enzymes or recombinant microorganisms that overexpress enzymes are provided. Plant seeds coated with free enzymes or recombinant microorganisms that overexpress enzymes are also provided. Compositions comprising a fertilizer and an enzyme or a recombinant microorganism that overexpresses an enzyme are provided. Modified enzymes having ACC deaminase activity, recombinant microorganisms expressing the modified enzymes, plant seeds treated with the modified enzymes or recombinant microorganisms, and methods for stimulating plant growth and/or promoting plant health using the modified enzymes or recombinant microorganisms are also provided.

Methods for promoting plant health using free enzymes and microorganisms that overexpress enzymes

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.
