Some Properties of Three Related Viruses: Andean Potato Latent, Dulcamara Mottle, and Ononis Yellow Mosaic

Abstract

SUMMARY: Three similar and apparently previously unrecorded viruses were studied and found to be most like viruses of the turnip yellow mosaic group. Andean potato latent virus (APLV) was obtained from primitive cultivated potatoes collected in the high tropical Andes, dulcamara mottle virus (DMV) from Solanum dulcamara L. growing near Rothamsted, and Ononis yellow mosaic virus from Ononis repens L. growing in many parts of England. All three viruses are readily transmitted by sap inoculation; APLV and DMV are transmitted through the seed of infected plants; DMV is transmitted by the flea beetle Psylloides affinis Paykull. Plants infected by one of the viruses are not protected against infection by the others.
