Abstract

To ascertain the biological link between BCMV and other host plants, a french bean infecting isolate was physically inoculated into various host plants. 13 host plants out of the 25 host plants examined were shown to be easily infected by the virus. Across plant species, there were differences in the incubation period required for symptom expression typical symptoms of mosaic, mottling and leaf rolling were produced on pea, pole bean and cowpea. The pole bean expressed symptoms after long incubation period (15-18 days). BCMV produced mosaic symptoms on green gram, moth bean, black gram and horse gram. A typical chlorotic and necrotic local lesion symptoms were produced with shorter incubation period on Glysine max L. (6-7 days), Nicotiana rustica (5-6 days) and Chenopodium amaranticolor (4-5 days). To verify the existence of BCMV, every plant was exposed to the Double Antibody Sandwich-Enzyme Linking Immunosorbent Assay (DAS-ELISA). The results demonstrated that the host plants that had distinct symptoms following mechanical sap inoculation had a good response to the antibody-specific.

Conclusion

The results of the experiments conducted in this study demonstrated that BCMV may be readily transmitted to other host plants through mechanical sap inoculation and can display a range of symptoms however, the host plants incubation times for expressing different symptoms differed. The hosts that were found to be susceptible to BCMV after mechanical injection may act as a reservoir for the virus. Therefore, the data acquired for this study may help with the prognosis of diseases and the development of appropriate management approach.
