The Potyviridae is the largest family of RNA plant viruses, members of which have single-stranded, positive-sense RNA genomes and flexuous filamentous particles 680–900 nm long and 11–20 nm wide. There are eight genera, distinguished by... more
Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security. CBSD is caused by two distinct species of ipomoviruses, Cassava brown... more
Potato Virus Y (PVY) is a pathogen of economic importance in pepper and other major crop species in the family Solanaceae. Three major PVY strain groups: O, C, and N, have been distinguished on the basis of genome sequencing. In this... more
Arracacha mottle virus (AMoV) is the only potyvirus reported to infect arracacha (Arracacia xan-thorrhiza) in Brazil. Here, the complete genome sequence of an isolate of AMoV was determined to be 9,630 nucleotides in length, excluding the... more

In sub-Saharan Africa, maize is a staple food and key determinant of food security for smallholder farming communities. Pest and disease outbreaks are key constraints to maize productivity. In September 2011, a serious disease outbreak,... more
Resumen (es_ES) Los potyvirus son uno de los grupos de virus más limitantes en los cultivos de papa (Solanum tuberosum y S. phureja) en el mundo, siendo PVY, PVV y PVA las especies más prevalentes. En este trabajo se evaluó la presencia... more
Pepper, Capsicum annuum L., is an economically important crop in Zimbabwe, grown as a spice and vegetable for both the local and export markets. Pepper is susceptible to infection by up to 49 virus species, some of which cause serious... more
Soybean mosaic virus (SMV) and peanut mottle virus (PMV) are two potyviruses that cause yield losses and reduce seed quality in infested soybean (Glycine max (L.) Merr.) fields throughout the world. Rsv1 and Rpv1 are genes that provide... more

The RNA silencing pathway mediated by small interfering RNAs (siRNAs) plays an important antiviral role in eukaryotes. To counteract this defense barrier, a large number of plant viruses express proteins with RNA silencing suppression... more
