Interpretive Summary:

Technical Abstract: The need to reliably detect and identify multiple plant pathogens simultaneously, especially in woody perennial hosts, has led to development of new molecular diagnostic approaches. In this study, a Luminex-based system was developed that provided a robust and sensitive test for simultaneous detection, identification and quantification of nine citrus pathogen targets. The assay included a target for a citrus housekeeping gene, Nad5, as an internal control. The protocol developed here is the first to successfully detect up to 10 targets in one multiplex assay. A procedure for high throughput robotic extraction and purification of pathogen nucleic acid targets, optimized for citrus tissue, was developed and used with the Luminex-based system to increase uniformity and cost effectiveness of the test. The assay is user friendly and can be applied to detect endemic and/or exotic plant pathogens in quarantine or certification programs.
