Soybean mosaic virus (SMV) is a member of the plant virus genus Potyvirus (family Potyviridae). It infects mainly plants belonging to the family Fabaceae but has also been found infecting other economically important crops.[HW 1][1] SMV is the cause of soybean mosaic disease that occurs in all the soybean production areas of the world. Soybean (Glycine max) is one of the most important sources of edible oil and proteins and pathogenic infections are responsible for annual yield losses of about $4 billion in the United States. Among these pathogens, SMV is the most important and prevalent viral pathogen in soybean production worldwide.[2] It causes yield reductions of about 8% to 35%, but losses as high as 94% have been reported.[HW 2]
The virus was first reported from Connecticut in 1915 and described in 1921.[3] Its genome is a single stranded positive sense RNA of about 9.5kb that encodes at least 11 proteins.[2] SMV virion is non enveloped, flexuous and filamentous of about 720–800 nm long and 12–15 nm in diameter.[4] Several strains of the SMV have been fully sequenced, consisting of 9,588 nucleotides (the sequenced data can be found on GenBank).[5]
