Peanut green mosaic virus — a member of the potato virus Y group infecting groundnut (Arachis hypogaea) in India uri icon

abstract

  • Peanut (groundnut) green mosaic virus was identified as a potyvirus by electron microscopy, aphid transmission and chemical properties. It was sap transmissible to 16 spp. in the Leguminosae, Solanaceae, Chenopodiaceae, Aizoaceae and Pedaliaceae. Phaseolus vulgaris was a good local lesion host. It remained infective in buffered groundnut leaf sap at dilutions of 10-3 after 3-4 days at 25 deg C or heating for 10 min to 55 deg but not 60 deg . It was transmitted in the non-persistent manner by Aphis gossypii and Myzus persicae but was not seed-borne. Purified preparations contained flexuous, filamentous particles c. 750 nm long which sedimented as a single component with a sedimentation coefficient (S deg 20,w) of 171S and contained a single polypeptide (mol. wt. 34 500 daltons) and 1 nucleic acid species (mol. wt 3.25 X 106 daltons). The virus is serologically unrelated to groundnut mottle virus and other viruses infecting leguminous crops. Infected leaves contained cylindrical, cytoplasmic inclusions
