The family Potyviridae includes >30% of known plant virus species, many of which are of great agricultural significance. These viruses have a positive sense RNA genome that is approximately 10 kb long and contains a single long ORF. The ORF is translated into a large polyprotein, which is cleaved into approximately 10 mature proteins. We report the discovery of a short ORF embedded within the P...
Habenaria mosaic virus (HaMV), a member of the genus Potyvirus in the family Potyviridae, was first discovered from Habenaria radiata in Japan. The complete genomic sequence of a South Korean isolate (PA1) of HaMV infecting Plantago asiatica L. was determined with high-throughput RNA sequencing.
PVY is a member of the Potyviridae, the largest plant virus family. For general information on PVY see the Web Site (life.anu.edu.au/viruses/ICTVdB/57010001.htm). Currently, three main strains of PVY are know. (i) PVY (ordinary or common strain) is widely distributed throughout the potato growning areas of the world. This strain induces mild to severe mosaic and can cause stem necrosis in some ...
Cowpea, (Vigna unguiculata L. (Walp)) is an annual tropical grain legume. Often referred to as "poor man's meat", cowpea is one of the most important subsistence legumes cultivated in West Africa due to the high protein content of its seeds. However, African cowpea production can be seriously constrained by viral diseases that reduce yields. While twelve cowpea-infecting viruses have been repor...
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 streak virus and Ugandan cassava brown streak virus, belonging to the family Potyviridae. Previously, CBSD was reported only from the coastal lowlands of East Afr...
The helper-component proteinase (HC-Pro) of potyvirus is involved in polyprotein processing, aphid transmission, and suppression of antiviral RNA silencing. There is no high resolution structure reported for any part of HC-Pro, hindering mechanistic understanding of its multiple functions. We have determined the crystal structure of the cysteine protease domain of HC-Pro from turnip mosaic viru...
