Persistent plant viruses have a unique natural history. They are cytoplasmic RNA viruses found in many plants, including many crop and ornamental plants, and are the most common type of virus found in wild plants. Persistent plant viruses have very long associations with their hosts. They do not move between plant cells, are found in every cell, and are only vertically transmitted. Their evolutionary history remains obscure but many aspects of their lifestyles imply mutualistic relationships with their plant hosts. Many are related to viruses of fungi, including endophytic fungi, and in some cases there is evidence for transmission between plants and fungi read more ...
