Research Project: DISCOVERY AND DEVELOPMENT OF NATURAL PRODUCT-BASED WEED MANAGEMENT METHODS

Location: Natural Products Utilization Research

Project Number: 6408-21410-006-00
Project Type: Appropriated

Start Date: Mar 23, 2006
End Date: Oct 18, 2010

Objective:
To discover phytotoxins and allelochemicals for use in pest management and to provide the fundamental information on mode of action, structure-activity relationships, natural resistance mechanisms, and biosynthesis of natural phytotoxins that will be required for development medicinal/nutraceutical crops. To discover, characterize, manipulate and utilize genes involved in the production of natural products and in chemical defense and resistance mechanisms against allelochemicals and environmental phytotoxins.

Approach:
Conduct bioassays in collaboration with research chemists during bioassay-directed isolation of new phytotoxins. Molecular sites of action will be determined with genomic and biochemical approaches. Biosynthetic pathways of toxins from plants will be investigated. Genes controlling synthesis of useful plant secondary products and plant defenses to phytotoxins will be identified, cloned, and manipulated.
