Abstract
A virus was isolated from spinach plants showing rugose symptom in Saitama prefecture. The virus was readily transmitted by sap inoculation and by aphid, but not through seed of spinach. The virus had similar host range to CMV-P, although it did not produce any symptoms on tomato and cucumber. The virus was spherical particles, 30nm in diameter, and was serologically indistinguishable from CMV-P. Electrophoresis of RNA of the virus revealed four component showing minor differences in mobility from the components of CMV-Y and CMV-P. We propose the name of the virus, CMV-SR.
