Technical Abstract: Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus (TCSV) emerged in Florida in 2009 and 2012, respectively, joining Tomato spotted wilt virus (TSWV), as economic threats to horticultural and agronomic crops in the southeastern U.S. Currently, GRSV, TCSV and TSWV infect solanaceous vegetable crops and occur sympatrically in south Florida. All U.S. GRSV isolates characterized to date have a reassorted genotype (LGMTSG) with GRSV S and L RNAs and a TCSV M RNA; this is the first known instance of an interspecies tospovirus reassortant. Methods were developed to detect reassortants in natural mixed infections and a study was initiated to examine reassortment in experimental mixed infections. A better understanding of these processes will enhance rational disease management and forecasting strategies.
