Project Type: Non-Assistance Cooperative Agreement
Start Date: Jun 1, 2021
End Date: Jun 14, 2024
Objective:
Develop novel means for detection of resistance-breaking tospoviruses and tomato resistance genes for tospoviruses.
Approach:
Previous work has demonstrated that genetic markers can be identified for tomato spotted wilt virus isolates that are able to overcome (“break”) resistance genes for this virus in tomato. Similar markers have been identified for these resistance genes in tomato. Robust genetic markers will be developed for resistance breaking in the related tomato chlorotic spot virus isolates in Puerto Rico. These tools and protocols will be used to analyze resistant tomato cultivars in Puerto Rico for resistance-breaking isolates of this virus.
