Abstract. The first recorded experimental transmission by a natural vector of a plant virus with filamentous particles (here termed a filamentous virus) appears to have been that of sugarcane mosaic potyvirus by the aphid Rhopalosiphum maidis (Brandes, ).

Because the potyviruses comprise the largest plant virus group and are among the most commonly occurring plant viruses, it is perhaps Cited by: The Voice of Landscape Ontario. Start Planning Your Success in Now with Exciting. Listings. Great. Sale plants.
