Project Number: 1275-22000-204-00
Project Type: Appropriated

Start Date: Mar 27, 2003
End Date: Mar 26, 2008

Objective:
1. Establish the etiology of novel diseases of citrus 2. Develop novel rapid, sensitive and quantitative diagnostic tests for the presence of exotic pathogens in plant tissues. 3. Identify the virulence mechanisms used by exotic pathogens 4. Maintain and facilitate cooperative research on the Exotic Pathogens of Citrus Collection

Approach:
We will characterize novel or exotic pathogens of citrus that threaten the U.S. citrus industry. This work will include the determination of the etiology of novel diseases, characterization of the diversity present in a pathogenic taxon, the development of diagnostic tests for the pathogen, and the development of information about disease processes and knowledge that may lead to control of the diseases. This project will also maintain and develop an extensive collection of exotic pathogens of citrus for use by this project and collaborators from the U.S. and around the world. Detection methods will be generally PCR-based, including real-time quantitative PCR. Antibodies will also be developed. The etiology of novel diseases will be established by plant inoculations both in the greenhouse in Beltsville and by field experiments in the countries where the disease exists.
