The invention relates to methods of producing a plant with delayed senescence comprising inducing at least one nucleotide deletion, insertion or substitution into at least one copy of a gene encoding deoxyhypusine synthase (DHS) in the plant, wherein the nucleotide deletion, insertion or substitution
decreases the activity of DHS encoded by the gene in the plant. The invention also relates to plants produced by the methods and progeny thereof.

The subject invention provides KB59A4-6 pesticidal proteins and preferred methods of using these proteins to control lepidoteran pests. This invention provides Bacillus thuringiensis isolate KB59A4-6.

Disclosed and claimed are novel Bacillus thuringiensis isolates, pesticidal toxins, genes, and nucleotide probes and primers for the identification of genes encoding toxins active against pests. The primers are useful in PCR techniques to produce gene fragments which are characteristic of genes encoding these toxins. The subject invention provides entirely new families of toxins from Bacillus isolates.

The specification discloses a nucleic acid from Bacillus thuringiensis strain KB59A4-6 that encodes a novel pesticidal SUP toxin and plants and microbial cells transformed with the nucleic acid.

Methods and compositions for the control of nematodes are disclosed. Specifically, fatty acid ester compounds have been found to advantageously control nematodes at concentrations which are non-phytoxic. The fatty acid ester compounds can be used in conjunction with other nematicidal agents such as free fatty acids, fatty acid salts, avermectins, ivermectin, and milbemycin. In another embodiment, the subject invention further provides methods for killing the eggs of nematodes. Thus, the subject… Show more

In another embodiment, the subject invention further provides methods for killing the eggs of nematodes. Thus, the subject invention further relates to the surprising discovery that certain fatty acid esters have ovicidal activity against nematode eggs. Show less

The subject invention concerns a means for discovery of microbes having useful activities. More specifically, the subject invention comprises the use of nematodes as the starting material for discovering novel strains of microbes such as Bacillus thuringiensis or other Bacilli. The nematodes are processed by Bacillus isolation techniques to recover the microbes.

Disclosed and claimed are novel nucleotide primers for the identification of genes encoding toxins active against nematodes and coleopterans. The primers are useful in PCR techniques to produce gene fragments which are characteristic of genes encoding these toxins. The primers are also useful as nucleotide probes to detect the toxins-encoding genes. The subject invention also concerns novel isolates, toxins, and genes useful in the control of plant pests.

The present invention discloses multifunctional recombinant DNA plasmid cloning vectors able to replicate and express dominant drug resistance markers in Escherichia coli, Streptomyces, and Actinomadura.

The invention provides a recombinant plasmid that is capable of inducing the expression of a brown pigment. The plasmid is a pARCl plasmid into which has been inserted DNA which includes a transcriptional terminator and a polylinker sequence.

Plasmid DNA was isolated from two Actinomadura species and characterized by mapping the sites of restriction endonuclease cleavages and by calculation of total molecular size.
