Resumo

Genomic reassortment is a well-documented process in multisegmented viruses, including members in the genus Orthotospovirus. Comparative analysis of partial fragments of the large (L), medium (M) and small (S) segments of two orthotospovirus isolates from Adenium obesum (known as desert rose) collected in Brazil showed a higher nucleotide similarity with groundnut ringspot virus (GRSV). However, genome sequence analysis of another isolate of orthotospovirus from A. obesum revealed a reassortment event involving GRSV and tomato chlorotic spot virus (TCSV) with L and M segments assigned to GRSV and S to TCSV (i.e., STCMGLG). The two GRSV isolates from A. obesum were not transmissible to any tested plants by mechanical inoculation, including A. obesum itself. In contrast, the STCMGLG isolate was mechanically transmitted to a number of indicator plants but not to A. obesum. Furthermore, neither STCMGLG nor GRSV isolates were able to overcome the Sw5 resistance gene in tomato. (AU)
