Research Project: Identification, Characterization, and Control of Seed-Transmitted New Diseases of Citrus

Location: Subtropical Plant Pathology Research

Project Number: 6034-22000-042-25-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2020

Objective:
1) Identify the causal agent(s) of these two disease. Based on the symptom development and disease progression, we suspect the causal agents could be associated with bacterial or viral pathogens; and 2) develop methods for rapid detection of these pathogens.

Approach:
1. Identification of Causal Pathogens: The primary suspects of the causal agents for both diseases are either bacteria or viruses based on visual symptoms and disease progression. A combination of traditional plant pathology approach and next generation sequencing and analysis will be used to increase the probability to identify the casual agents. 2. Development of Methods for Rapid Identification of the Pathogens: Once the nature and the identity of the pathogens are known, it is feasible to develop qPCR-based and antibody-based methods for their rapid identification.
