The accurate classification of viral dark matter–metagenomic sequences that originate from
viruses but do not align to any reference virus sequences–is one of the major obstacles in …

Virus metagenomics is a young research filed but it has already transformed our
understanding of virus diversity and evolution, and illuminated at a new level the …

Kitaviridae is a family of plant-infecting viruses that have multiple positive-sense, single-
stranded RNA genomic segments. Kitaviruses are assigned into the genera Cilevirus …

Six novel insect-specific viruses, isolated from mosquitoes and phlebotomine sand flies
collected in Brazil, Peru, the United States, Ivory Coast, Israel, and Indonesia, are described …

While a large number of negative-strand (−) RNA viruses infect animals and humans, a
relative small number have plants as their primary host. Some of these have been classified …

There may be many factors contributing to reduction in longevity and productivity in passion
fruit plants, especially diseases of viral, bacterial or fungal etiologies, among which passion …

The etiology of citrus leprosis was initially contested. In the United States, Fawcett and

Citrus leprosis complex is an emerging disease in the Americas, associated with two
unrelated taxa of viruses distributed in South, Central, and North America. The cytoplasmic …

Aphids (order Hemiptera) are important insect pests of crops and are also vectors of many
plant viruses. However, little is known about aphid-infecting viruses, particularly their …
