Aphid transmission of nanoviruses [PDF]
Archives of Insect Biochemistry and Physiology, 2020 AbstractThe genus Nanovirus consists of plant viruses that predominantly infect legumes leading to devastating crop losses. Nanoviruses are transmitted by various aphid species. The transmission occurs in a circulative nonpropagative manner. It was long suspected that a virus‐encoded helper factor would be needed for successful transmission by aphids ...
