Orchid fleck dichorhavirus movement protein shows RNA silencing suppressor activity [PDF]
Journal of General Virology, 2022 To counteract RNA interference-mediated antiviral defence, virus genomes evolved to express proteins that inhibit this plant defence mechanism. Using six independent biological approaches, we show that orchid fleck dichorhavirus citrus strain (OFV-citrus) movement protein (MP) may act as a viral suppressor of RNA silencing (VSR).

Pest categorisation of Citrus leprosis viruses [PDF]
EFSA Journal, Volume 15, Issue 12, December 2017., 2017 Abstract The EFSA Panel on Plant Health performed a pest categorisation of the Citrus leprosis viruses for the EU territory and identified five distinct viruses, Citrus leprosis virus C (CiLV‐C), Citrus leprosis virus C2 (CiLV‐C2), Hibiscus green spot virus 2 (HGSV‐2), the Citrus strain of Orchid fleck virus (OFV) and Citrus leprosis virus N sensu novo

Journal of Economic Entomology, 2020 Abstract The incidences of Citrus leprosis virus C (CiLV-C) and Orchid fleck dichorhavirus Citrus strain (OFV-citrus) were determined in field populations of Brevipalpus mites from 15 citrus-producing states in Mexico. Mites were collected from orange, grapefruit, mandarin, lime, and sweet lime orchards.

Identification and Characterization of Citrus Chlorotic Spot Virus, a New Dichorhavirus Associated with Citrus Leprosis-Like Symptoms [PDF]
Plant Disease, 2018 Local chlorotic spots resembling early lesions characteristic of citrus leprosis (CL) were observed in leaves of two sweet orange (Citrus sinensis L.) trees in Teresina, State of Piauí, Brazil, in early 2017. However, despite the similarities, these spots were generally larger than those of a typical CL and showed rare or no necrosis symptoms.

Arabidopsis thaliana as a model host for Brevipalpus mite-transmitted viruses [PDF]
Scientia Agricola, 2017 : Brevipalpus-transmitted viruses (BTV) are a taxonomically diverse group of plant viruses which severely affect a number of major crops. Members of the group can be sub-classified into cytoplasmic (BTV-C) or nuclear type (BTV-N) according to the ...

HISTOPATHOLOGICAL PATTERNS OF LESIONS CAUSED BY TWO DICHORHAVIRUS [PDF]
BRAZILIAN JOURNAL OF AGRICULTURE - Revista de Agricultura, 2020 Different from most plant viruses, Brevipalpus mite-transmitted viruses (BTV) cause localized infection, not being able to systemically invade the infected plant. To broaden the specter of the histopathological changes in leaf tissues induced by BTV infection, we examined the tissue organization of leaf lesions caused by the infection of two ...

Smilax auriculata: A New Host for Orchid Fleck Dichorhavirus Identified in Florida, USA [PDF]
Plant Disease, 2022 In June 2020, Orchid fleck virus (OFV) was detected in a species of Liriope in Leon and Alachua County, Florida (Fife et al; 2021). In October of the same year, four adjacent dune/ear-leaf greenbrier vines, Smilax auriculata (Smilaceae: Liliales), showed yellowing and mottling symptoms (Figure 1). Infected and healthy S.
