Abstract

Abstract A virus, first reported from China in 1983 as producing a mild mottle in peanut (Arachis hypogaea) was further characterized and named peanut stripe virus (PStV) in the USA. It has since been reported from major groundnut‐growing areas in South‐east Asia including India, and has been found to cause economically significant crop losses. Besides groundnut, it infects soybean (Glycine max) cowpea (Vigna unguiculata), Indigofera amoena, Pueraria phaseoloides, Stylosanthes capitata and S. craba naturally. It is seedborne and transmissible mechanically by sap as well as by the aphid Aphis craccivora. The movement of infected seed has resulted in its wide dissemination. The virus is serologically closely related to blackeye cowpea mosaic potyvirus (BICMV), Azuki bean mosaic potyvirus (AzMV) and the serogroup B strains of bean common mosaic potyvirus (BCMV), and distantly to clover yellow vein and soybean mosaic potyviruses. PStV was initially described as a new virus, but recent molecular studies have s...
