First Report of Brevipalpus papayensis as Vector of Coffee ringspot virus and Citrus leprosis virus C

open access: yesPlant Disease, 2018
Coffee ringspot virus (CoRSV) and Citrus leprosis virus C (CiLV-C) are two emergent pathogens that can cause significant losses to coffee and citrus, respectively. Recently, it was verified that Brevipalpus phoenicis, originally reported as vector of these viruses, is indeed a complex group reclassified into eight mite species (Beard et al.

Pest categorisation of Longidorus diadecturus [PDF]

open access: yes, 2017
The Panel on Plant Health performed a pest categorisation of Longidorus diadecturus (Nematoda: Longidoridae) for the EU. The nematode is a well-defined taxon and was described from Ontario, Canada and later reported from some states in the USA.

Orchid fleck dichorhavirus movement protein shows RNA silencing suppressor activity. [PDF]

open access: yes, 2022
[EN] 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 ...

Reproductive performance of the mite Brevipalpus phoenicis (Geijskes, 1939) on citrus and coffee, using life table parameters

open access: yesBrazilian Journal of Biology
The flat-mite Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) is considered important in citrus (Citrus spp.) and coffee plants (Coffea spp.) in Brazil, and is known as the leprosis and coffee ring spot mite, as being a vector of the Citrus

Powerful sequence similarity search methods and in-depth manual analyses can identify remote homologs in many apparently "orphan" viral proteins. [PDF]

open access: yes, 2014
The genome sequences of new viruses often contain many "orphan" or "taxon-specific" proteins apparently lacking homologs. However, because viral proteins evolve very fast, commonly used sequence similarity detection methods such as BLAST may overlook ...
