Abstract
The present invention is directed to methods of modifying the plant development process comprising of exposing a plant or plant part to volatiles biosynthesized by one or more bacteria or enzymes. Specifically, the embodiment uses one or more bacteria selected from the plant growth promoting bacteria group consisting of Rhodococcus spp., Pseudomonas spp., Bacillus spp., or Xanthobacter spp., or a mixture thereof. A closed apparatus, FIG. 1A, containing a tri-phasic system is used to expose the bacteria to hydrocarbons, iron, cyanide, and/or ammonium compounds; the method induces the biocatalyst to biosynthesize volatile compound(s) that deter ethylene production in climacteric plants or fruit resulting in the biocatalyst ability to delay fruit ripening.
Claims4
A method of reducing fungal infections in climacteric fruit or plants comprising:
- inducing bacteria of the genus Rhodococcus, genus Pseudomonas, genus Bacillus, genus Xanthobacter to express dehydratase, nitrile hydratase and monooxygenase enzymes by culturing the bacteria under an atmosphere comprising ethylene and/or propylene with the co-inducers iron and urea and wherein no cobalt is present, and wherein the bacteria convert the ethylene and/or propylene into volatile compounds,
- applying the resulting volatile compounds either directly or indirectly to climacteric fruit or plants in order to reduce fungal infection.
