Abstract:
The present invention provides a method for controlling crown gall disease in plants using an effective quantity of α-proteobacteria that produces trifolitoxin (TFX). The present invention also provides a biocontrol agent for use in the above method, and a plant coated with the biological control agent. The biocontrol agent is characterized as a biologically pure culture of an α-proteobacteria strain that produces TFX, or an α-proteobacteria strain genetically engineered to produce TFX. The α-proteobacteria strain employed may include any one of the many strains of capable of producing crown galls, including and, in particular, F2/5. The α-proteobacteria strain employed may be genetically engineered to produce TFX by introducing a genetic construct into the so as to cause the to carry and express the tfx operon from. The bacteria may also be genetically engineered to produce TFX by introducing a pT2TFXK plasmid into the. The biocontrol agent may also be the strain F2/5 (pT2TFXK), ATCC Patent Deposit Designation PTA-2356.

Materials And Methods For Enhancing Nitrogen Fixation In Plants
The subject invention concerns materials and methods for providing or enhancing nitrogen fixation in plants. The invention provides for the use of nitrogen fixing bacteria that are isolated from nitrogen efficient plants. Plants for which enhanced nitrogen fixation is desired are inoculated with an effective amount of nitrogen firing bacteria of the invention. In an exemplified embodiment, the bacteria is Kp342. The subject invention also concerns means to increase the number of free-living nitrogen-fixing bacteria in plants. Mutants of beneficial endophytic bacteria that are resistant to plant defense responses can be used to colonize a plant in numbers higher than a wild type or a non-mutated bacteria can colonize a plant. The higher number of bacteria colonizing the plant provide for more nitrogen fixation for the plant. The subject invention concerns methods for producing non-leguminous plants that are capable e of utilizing atmospheric nitrogen by colonization with a nitrogen fixing endophyic bacteria that is resistant to plant defense responses. The subject invention also concerns the plants produced by the subject method. The subject invention also concerns methods for producing the mutant endophytic bacteria. The subject invention also concerns the mutant endophytic bacteria produced using the subject methods.

Plasmid For Transformation Of Root Nodule Bacteria
A plasmid for use in root nodule bacteria is described which is intended both to increase yield of inoculated legume plants inoculated with the bacteria as well as aiding in the competitiveness of the bacteria with native strains. The plasmid include a hydrogen uptake element which aids in energy efficient nitrogen fixation by the plant bacteria symbiotic pair as well as a toxin and resistance element intended to aid in the competitive fitness of the inoculant bacterial strain.
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.
The sequences of a Rhizobium bacteria responsible for competitiveness with respect to plant nodulation have been isolated and permanently transferred to superior nodulating Rhizobium genome. This has resulted in a stable construct that can form a plant inoculant that yields effective nodulation, while reducing the risk of suppression by other bacteria in the environment.
A novel category of microorganisms has been identified from its ribosomal DNA (rDNA) sequence. That sequence, P36, is characteristic of this category of microorganisms, here termed metathermophiles. Methods for isolating samples of metathermophiles using the rDNA sequence are described.
