Peanut stunt virus (PSV)

This virus is widespread and causes epidemics in legume crops like groundnuts, beans or soybeans. The symptoms include stunting, chlorosis, leaf and seed mottling, as well as malformations. In soybeans, infections result in yield losses and reduced seed quality. It can be transmitted by several species of aphids in a non-persistant manner, by mechanical means, as well as through seeds.

The genome consists of 3 positive-sensed, single-stranded RNA molecules. The strains of PSV have been assigned to four subgroups. Some of them are associated with satellite RNAs.
