New tospovirus from Brazil
A new tospovirus isolate originating from Brazil had been investigated and found distinct from tomato spotted wilt tospovirus (potential EPPO A2 quarantine pest) and impatiens necrotic spot tospovirus (potential EPPO A2 quarantine pest). The isolate systemically infected Petunia hybrida, but did not infect Cucumis sativus. Analysis of its single stranded RNA (S RNA) indicated that the new isolate is more closely related to the TSWV isolates than to INSV. The isolate was provisionally designated as TSWV-B until further biological and molecular evidence allow a further and more precise classification.
