Abstract
Root nodule bacterial strains are designed specifically to aid in the growth of soybeans. A high copy number plasmid is described to make trifolitoxin, an antibiotic. The plasmid is preferably hosted in a Sinorhizobium species which is capable of nodulating roots of soybean plants. The phenotype of trifolitoxin production confers a competitive advantage on the inoculant strains by inhibiting competitive strains. To facilitate soybean growth a separate hydrogen uptake capability is also included in the inoculant, either in the same Sinorhizobium strain or in a companion trifolitoxin-resistant strain of root nodule bacteria introduced in the same inoculant.
