Abstract Indirect ELISA studies revealed that the most frequently detected virus in all tested plants showing mosaic symptoms was Bean Yellow Mosaic Virus (BYMV). The virus-induced symptoms in diagnostic hosts revealed that mosaic on faba bean, chloritic mosaic on cowpea, local lesions on Chenopodium amaranticolor. Electron micrographs of ultrathin sections prepared from BYMV-infected faba bean leaves showed aggregates of virus particles randomly distributed in the cell and mitochondrial degeneration. Two bacterial isolates were selected upon their antiviral activity, phenotypically characterized, 16S rRNA sequenced and identified as Bacillus sp and Rhizobium etlli (Abis-Alexandria) In vivo, the application of the Bacillus treatment showed the highest shoot and fresh root weight with 46.33 and 48.7 g, respectively, followed by Rhizobium treatment with 41.67 and 43.3g. Compared to control, the viral treatment only exhibited the lowest weight with 20.67and 21.7g. The Phenolic content (TPC) in the Rhizobium treatment showed the highest content with 21.54 GAE mg/100g extract compared to control 10.17 GAE mg/100g extract. The virus treatment showed a relative accumulation level of 11.50 GAE mg/100g extract |
