Samples from 1294 plants representing different cultivars were analysed by Enzyme-linked immunosorbent assay (ELISA) and Dot immunobinding assay (DIBA). The data showed that green-house cucumbers are infected by CMV, ZYMV, TSWV and WMV-2. However, ZYMV was the most prevalent virus. Mixed infection including double and triple infection was identified in some samples. Transmission of aphid-borne viruses (CMV, ZYMV and WMV-2) by Aphis gossypii, A. fabae, A. craccivora and Myzus persicae revealed that ZYMV is most efficiently vectored by these aphids and, A. craccivora transmitted these viruses with more than 60% efficiency. In addition, WMV-2 was not transmitted by A. gossypii. In RT-PCR, ZYMV infection was confirmed by amplifying a PCR product of the predicated size 458 bp, using total RNA extracted from infected plants. All ZYMV infected samples reacted with monoclonal antibodies (705-1, 705-2 and 705-4) in TAS-ELISA test. These results showed that ZYMV isolate collected from Jiroft belongs to group A, cluster 1 or 2. In electron microscopy study, normal length of ZYMV flexuous particles in partial purified preparation was calculated as 790 nm. The molecular weight of coat protein of ZYMV was estimated at 36 KDa., using SDS-PAGE and western blotting. This is the first report of these viruses in greenhouse grown cucumber in the Jiroft region. SP - 393 EP - 407 AU - M. Shabanian, AU - H. Masomi, AU - A. Hoseinipour, AU - J. Heidarnejad, AU - Z.
