Title: R James Cook: Innovator in Biocontrol Agents
Introduction
R James Cook is a prominent inventor based in Pullman, WA (US), known for his significant contributions to the field of biocontrol agents. He holds a total of 7 patents, showcasing his innovative approach to controlling plant diseases caused by soil-borne fungi.
Latest Patents
His latest patents include the development of biocontrol agents for take-all, specifically utilizing fluorescent Pseudomonas spp. These agents are effective in managing diseases caused by soil-borne fungi, such as take-all, in small grain crops and turf grass. The biocontrol strains exhibit a unique genotype, characterized by a distinctive banding pattern. They demonstrate superior root-colonizing ability, with higher population density on roots and extended colonizing activity compared to known Gg-suppressive strains. Additionally, these strains can replicate the level of biocontrol found naturally in take-all decline soil. Methods for isolating and identifying these strains, as well as their application in disease control, are also provided. Notably, strains NRRL B-21806 and NRRL B-21807 are highlighted in his work.
Another significant patent involves transgenic strains of Pseudomonas designed for biocontrol of plant root diseases. These transgenic fluorescent Pseudomonas spp. possess a biosynthetic locus that encodes the production of the antibiotic phenazine-1-carboxylic acid, which has been stably introduced into their genome. They also have a locus for producing the antibiotic 2,4-diacetylphloroglucinol, making them effective against diseases caused by soil-borne fungi such as Rhizoctonia and Pythium.
