Survey on soybean viruses in Iran
A survey was conducted in five main soybean-producing provinces of Iran (Golestan, Mazandaran, Ardebil, Lorestan and Khuzestan) in 1999-2000 to study the presence of soybean viruses. 3110 leaf samples were collected from 80 soybean fields, and tested for the presence of 13 viruses: Alfalfa mosaic alfamovirus (AMV), Bean common mosaic potyvirus (BCMV), Bean yellow mosaic potyvirus (BYMV), Blackeye cowpea mosaic virus (BlCMV), Cucumber mosaic cucumovirus (CMV), Pea enation mosaic enamovirus-1 (PEMV-1), Peanut mottle potyvirus (PeMoV), Soybean mosaic potyvirus (SMV), Tobacco mosaic tobamovirus (TMV), Tobacco ringspot nepovirus (TRSV) (EPPO A2 quarantine pest), Tomato ringspot nepovirus (ToRSV) (EPPO A2 quarantine pest), Tomato spotted wilt tospovirus (TSWV) (EPPO A2 quarantine pest) and Tobacco streak ilarvirus (TSV). All viruses were found*. The overall virus incidence was 15.4%. SMV, TSV, TRSV, ToRSV and TSWV had previously been recorded in soybean in Iran and AMV, BCMV, BYMV, CMV, PEMV-1 and PeMoV on other hosts. The authors note that this is the first report of naturally occurring infections of 8 viruses in soybean fields in Iran: AMV, BCMV, BlCMV, BYMV, CMV, PEMV-1, PeMoV and TMV.
