The atypical Brevipalpus-transmitted viruses and their interactions with host plants and mite vectors.
The role of Brevipalpus mites as vectors of plant viruses has been known for decades. However, only recentlj their relevance has been acknowledged. The Iist of Brevipalpus-transmitted viruses (BrTV) has increased ir. the last years, reaching close to 50, along with the economic importance 01' the diseases caused by them. The most studied BrTV is the Citrus leprosis vírus C (CiLV-C) due to the losses it causes to the citrus industry in the Americas. Also, Coffee ringspot vírus (CoRSV), Passion fruit green spot vírus (PFGSV), and Orchid fleck viru. (OFV) are of economic importance, wíth the later being the only BrTV with worldwíde distríbutíon probabl. due to the intense intematíonal market of orchids. In the last decade, most of what was accepted about CiLV-C and its interactions with the host and the vector was shown to be inaccurate. Our data bring novel information or its taxonomic classification (originally believed to be a rhabdovirus and now considered the type-member of the recently created Cilevirus), its persistent circulative (and not propagative, as originally proposed) interaction witl B. phoenicis, and the type of response it induces in its host (initially thought to be a HR-type of resistance ane now shown to be typical of compatíble host-virus interaction).
