Interpretive Summary: Historically, Tomato spotted wilt virus and Impatiens necrotic spot virus have been significant constraints to crop production worldwide. With the emergence of Tomato chlorotic spot virus and a natural Groundnut ringspot virus reassortant in Florida and the Caribbean region, the significance of tospoviruses in production of major solanaceous vegetables including tomato and pepper has increased.
Technical Abstract: Tomato chlorotic spot virus (TCSV) has been reported in common weeds including American black nightshade and jimsonweed in Florida and/or Puerto Rico. Experimental host range studies demonstrated that TCSV and/or GRSV can also infect ornamentals including petunia, brugmansia and garden impatiens. During 2014, the first natural TCSV infections of porcelainflower, false Christmas cactus and annual vinca were detected in Florida. Since then, TCSV has been documented in other important crop and weed species, indicating host and geographic range expansion of this tospovirus. In view of projected climate change-driven shifts in cropping systems, further knowledge of emerging plant viruses in Florida and the Caribbean region will help strengthen agricultural security.
