“…OFV has been found worldwide due to the global exchange and trade of orchid plants. In contrast to OFV, CoRSV has been reported in only two countries, Brazil and Costa Rica (Bittancourt 1938; Chagas et al, 1981; Rodrigues et al, 2002). Whereas phylogenetic analysis of OFV showed little geographical relationship between isolates, genetic variation in CoRSV is largely dependent on the distance between collection sites (Ramalho et al 2016).…”

The family Rhabdoviridae consists of mostly enveloped, bullet-shaped or bacilliform viruses with a negative-sense, single-stranded RNA genome that infect vertebrates, invertebrates or plants. This ecological diversity is reflected by the diversity and complexity of their genomes. Five canonical structural protein genes are conserved in all rhabdoviruses, but may be overprinted, overlapped or interspersed with several novel and diverse accessory genes. This review gives an overview of the characteristics and diversity of rhabdoviruses, their taxonomic classification, replication mechanism, properties of classical rhabdoviruses such as rabies virus and rhabdoviruses with complex genomes, rhabdoviruses infecting aquatic species, and plant rhabdoviruses with both mono- and bipartite genomes.

“…It has been reported also from the Philippines (Valdez, 1967), but probably the Asiatic disease is different because seed-transmitted, while CoRSV is not, and the vector is not known. CoRSV, like CiLV, is mechanically transmitted to some herbaceous hosts, mainly C. amaranticolor in which it causes only local lesions (Chagas et al, 1981). Carvalho & Figueira (1998) found that an isolate of CoRSV was systemic in C. amaranticolor and other hosts.…”

Citrus leprosis disease, caused by citrus leprosis virus (CiLV), had severe effects on sweet oranges in Florida (US) until the 1920s, after which it became rare. In South America, it appeared in the 1930s, first in Argentina and then in Brazil, where it is now widespread and very dangerous. It has also been reported in Paraguay, Peru, Uruguay and Venezuela. CiLV is transmitted by three species of Brevipalpus, mainly Brevipalpus phoenicis. The virus mainly attacks sweet orange, but also citrange, citron, Cleopatra mandarin, grapefruit, lemon, mandarin, sour orange and tangor. CiLV is a non‐enveloped rhabdovirus characterized by bacilliform particles measuring 120–130 × 50–55 nm, present in mesophyll and vascular parenchyma within cisternae of the endoplasm reticulum. Viroplasm structures are present in the infected cells. CiLV has been partially purified and its dsRNA as been investigated. It is mechanical transmissible to 13 test plant species belonging to the genera Atriplex, Beta and Chenopodium (Chenopodiaceae), Gomphrena (Amaranthaceae), and Tetragonia (Tetragoniaceae). Using some of these herbaceous test plants, grown at a suitable temperature, it is possible to diagnose CiLV in 3–4 days. CiLV is covered by lists and requirements in phytosanitary regulations, but the information given is often misleading. For phytosanitary purposes, it is important to consider the following main points: (a) both CiLV and its vectors need to be considered; (b) sweet orange fruits can be infected even more than propagation material; and (c) CiLV does not infect susceptible citrus systemically, or any of its known hosts.

“…The viral nature of the Coffee ringspot was inferred by electron microscopy which revealed the presence of short rod-like particles in the nucleus and cytoplasm and a characteristic electron lucent inclusion (viroplasma) in the nucleus (Kitajima and Costa, 1972;Chagas, 1980), its transmission by the tenuipalpid mite Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) (Chagas, 1973), and mechanical transmission to Chenopodium quinoa Willd., C. amaranticolor Coste & Reyn. and Gomphrena globosa L. (Chagas et al, 1981). The causal virus was named Coffee ringspot virus (CoRSV).…”

Coffee ringspot is a minor coffee disease caused by the nuclear type of Brevipalpus mite-transmitted virus, Coffee ringspot virus (CoRSV). Recently outbreaks of the disease in some growing regions of the state of Minas Gerais, Brazil, were registered with qualitative and quantitative yield losses. Coffea arabica was the only species registered as natural host. A survey was made on a germplasm collection of Coffea and related species kept at the Centro de Café "Alcides Carvalho", Instituto Agronômico, Campinas, state of São Paulo (SP), Brazil, to assess natural susceptibility of Coffee species, other than C. arabica and some interspecific hybrids of Coffea as well as other non-Coffea plant species to the Coffee ringspot virus (CoRSV). The following plants were found with ringspot symptoms on their leaves and/or fruits besides C. arabica L.: C. kapakata (IAC 4511), C. dewevrei cv. Excelsa, C. canephora cv. Robusta, hybrid derivative of the C. arabica × C. racemosa (IAC1195-5-6-2), C. arabica × C. dewerei (Piatã IAC 387), Híbrido de Timor CIFC 832/1 (derivative from a natural crossing between C. arabica × C. canephora) and C. racemosa. Also Psilanthus ebracteolatus, a species close to the genus Coffee was also found with ringspot lesions on their leaves. All these plants were also found infested by Brevipalpus mites identified as B. phoenicis. Infection of these plants by CoRSV was confirmed by the observation of characteristic cytopathic effects in the tissues of the lesion and by RT-PCR using a pair of primer specific for CoRSV. Only with C. racemosa RT-PCR failed to amplify the CoRSV genome. The susceptibility of P. ebracteolatus to CoRSV adds new dimension regarding its controversial taxonomic position
