A new tospovirus serogroup IV species infecting capsicum and tomato in Queensland, Australia

A previously undescribed tospovirus infecting tomato, capsicum and chilli in Queensland was characterised. The virus reacted with antibodies to serogroup IV tospoviruses, and the complete nucleotide sequence of its nucleocapsid protein gene indicated that it was a new tospovirus species. Sequence identities at the nucleotide and amino acid levels were <85% with recognised members of serogroup IV The virus infected test plants in five families and, importantly, overcame the Sw-5 resistance gene in tomato and TSWV resistance in Capsicum chinense accessions PI 152225, PI 159236 and AVRDC 00943. The name Capsicum chlorosis virus (CaCV) is proposed for this virus.
