Abstract:
... Sugarcane streak mosaic virus (SCSMV; genus Poacevirus, family Potyviridae) is a major causal agent of sugarcane mosaic disease in Asia. A survey of SCSMV was conducted in cultivated fields in Khuzestan province, southwestern Iran. Sixty-five sugarcane leaf samples showing mosaic symptoms were collected and investigated by RT-PCR. Almost one-fourth of the samples were found to be infected by SCSMV ...
