Research Project:
Characterization & Epidemiology of Citrus Tristeza Virus & Other Invasive & Emerging Graft-Transmissible Diseases of Citrus in California
Location: Crop Diseases, Pests and Genetics
Project Number: 5302-22000-009-00
Project Type:
Appropriated
Start Date: Apr 09, 2007
End Date: Apr 08, 2012
Objective:
Determine genetic diversity of tristeza and stubborn disease agents in California; 2)Characterize tristeza and stubborn biologically by graft and vector passage; and 3)Examine patterns of spatial and temporal spread of tristeza and stubborn.
Approach:
Isolate, identify, and characterize field strains of tristeza and stubborn in California with respect to phenotype, vector transmissibility, serology, molecular structure and phylogeny, and epidemiology. This will be accomplished by using a combination of the following: enzyme-linked immunosorbent assay (ELISA); reverse transcription (RT) polymerase chain reaction (PCR); conventional PCR; real time PCR; transmission electron microscopy; dark field microscopy; bacterial culturing in cell-free media; cloning; sequencing; spectrophotometry; electrophoresis; insect transmission; geostatistics; and ARC-GIS.
