Research Summary:

Small fruits virus diseases have been understudied and several new virus complexes have emerged in the last decade causing detrimental losses.  One of the goals of our research is to understand the epidemiology of small fruit virus complexes and implement cultural and pest management strategies to minimize disease impact.  Blackberry yellow vein disease (BYVD) and diseases associated with graft transmissible agents in blueberry are two major projects in progress in our laboratory.  BYVD is a devastating disorder that causes major losses in blackberry in the Southern United States.  More than 12 new and old viruses are involved in the disorder and we are collaborating with scientists in Oregon, California, Mississippi and the Carolinas to understand the epidemiology of each virus involved in disease development.  On blueberry we are working with the effects of Blueberry mosaic and Tobacco ringspot viruses on plant establishment and long term viability. 

We have several projects on ornamental viruses, especially those belonging to the genus Emaravirus, negative-strand RNA viruses that replicate in their mite vectors.  We use four emaravirus species in our efforts to understand the virus-vector interactions and the role of virus genes in replication and disease onset.

Soybean, the most important crop for Arkansas, suffers significant losses due to virus infection.  We are working on vein necrosis virus, the most widespread soybean virus in the United States.  Our work on this virus focuses on the virus epidemiology, identification of resistance in varieties and accessions and virus gene function in association to the necrosis symptoms often observed with vein necrosis infection.
