Interpretive Summary:

Technical Abstract: Among known tospoviruses, Tomato spotted wilt virus (TSWV; genus Tospovirus, family Bunyaviridae) continues to be the major viral disease affecting a wide range of agricultural and horticultural crops worldwide. Like many other RNA viruses, TSWV is known to maintain heterogeneous and divergent populations with individual isolates that have distinct biological and virulence characteristics. Adaptation of TSWV isolates to new hosts and development of resistance-breaking isolates capable of overcoming Tsw and Sw5 resistance genes are challenging the sustainability of management systems against the virus. As we strive to develop better management strategies with greater sustainability, it is critical to gain a deeper understanding of genetic diversification of the virus. Towards this objective, we have begun to analyze genetic diversity among S- and M-RNA segments of field isolates of TSWV collected from different plant species in California, North and South Carolina, New Mexico, New York, Virginia and Washington.
