Sweet Potato Mild Mottle Virus
Sweet potato mild mottle virus (SPMMV) is a plant pathogenic virus of the family '' Potyviridae''. Host and symptoms Sweet Potato Mild Mottle Virus (or SPMMV) has a large host range. This is uncommon for potyviruses, making SPMMV a divergent species of potyviruses. SPMMV hosts include 45 different species in 14 different plant families. The naturally occurring host, and namesake for the virus is ''Ipomoea batatas'' (sweet potato). Even though SPMMV is found naturally in sweet potato, scientists have been able to experimentally transmit the virus to different species including beets, sowbane, devil’s snare, makhmali, tomato, tobacco, petunia, and zinna. Some common symptoms seen in SPMMV hosts include mild leaf mottling, which is characterized by irregular patterns of marks, patches, spots, and streaks of different colors on host leaves. Also, stunting and dwarfing of the plant is common. Some hosts even have venial chlorosis. Overall, plant growth is very poor in hosts with SPM ...

Potyviridae
''Potyviridae'' is a family of positive-strand RNA viruses that encompasses more than 30% of known plant viruses, many of which are of great agricultural significance. The family has 12 genera and 235 species, three of which are unassigned to a genus. Structure Potyvirid virions are nonenveloped, flexuous filamentous, rod-shaped particles. The diameter is around 12–15 nm, with a length of 200–300 nm. Genome Genomes are linear and usually nonsegmented, around 8–12kb in length, consisting of positive-sense RNA, which is surrounded by a protein coat made up of a single viral encoded protein called a capsid. All induce the formation of virus inclusion bodies called cylindrical inclusions (‘pinwheels’) in their hosts. These consist of a single protein (about 70 kDa) made in their hosts from a single viral genome product. Member viruses encode large polypeptides that are cleaved into mature proteins. In 5'–3' order these proteins are * P1 (a serine protease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
