My research focuses on grapevine fanleaf virus (GFLV), a nematode vectored virus capable of causing significant yield losses in Vitis vinifera grapes. My current project aims to determine the GFLV genetic sequence responsible for causing symptoms in the model species Nicotiana benthamiana, as well as to figure out the mechanism of symptom development. It is hoped that lessons learned in conducting this project in a model species will be helpful in studying GFLV symptoms in grapes.
