Abstract

A virus was isolated from grain amaranth (Amaranthus hypochondriacus L.) showing mosaic symptoms. The virus infected 20 plant species of 8 families, and was readily transmitted by aphid. The thermal inactivation point of the virus in crude sap was 55-60°C (10min), dilution end point 10-3-10-4, and longevity in vitro 2-4 days at 25°C. The virus was isometric about 28-30nm in diameter, and was serologically indistinguishable from a yellow strain of cucumber mosaic virus (CMV-Y). Electrophoretic patterns of dsRNA of the virus were similar to those of CMVs. Based on these results, the virus was identified as CMV.
