Beet pseudoyellows virus (BPYV) is a species of virus in the genus Crinivirus . [1]
The virus was first recognised by James E. Duffus of the United States Department of Agriculture, and reported in 1975 under the title 'A new type of whitefly-transmitted disease – a link to the aphid-transmitted viruses'. [2] Beet ( Beta vulgaris ) in a research greenhouse unexpectedly presented symptoms characteristic of the aphid-vectored virus Beet yellows virus, despite no aphids being present. Instead, greenhouse whiteflies ( Trialeurodes vaporariorum ) were present and determined to be the vector. The presumed new species of virus was designated 'Beet pseudo-yellows virus' (note the hyphen, omitted in the currently accepted name). Further investigation revealed the virus typically causes stunting, interveinal yellowing, and/or chlorotic spotting in its hosts, and that at least an additional 36 species of plants from various families are susceptible to infection.
