Abstract

The Objectives of this study were to: -   Isolate and identify Bean yellow mosaic virus affecting bean and faba bean plants under field conditions from different locations in Menoufia governorate. Yellowing, mosaic malformations and blisters were appeared on infected leaves. Symptomatic plants were tested by biological methods as  host range and indicator plants, serological tests and PCR method. -   Study of some inhibitors (Plant extracts and salicylic acid (SA) against BYMV. Evaluate systemic acquired resistance (SAR) using host local lesions (Chenopodium amaranticolor) and Dianthus caryophyllus extract was found to be the most effective inducer (95.8%). -   Study the biochemical changes in induced, infected and healthy plants, photosynthesis pigments (chlorophyll a, chlorophyll b and carotenoids), oxidative enzymes (peroxidase and polyphenol oxidase) and antiviral protein. -   Examine the histological changes using light and electron microscopy, revealed changes as affecting on  mesophyll layers, spongy tissue and decrease in number of chloroplasts and increase of starch grains in infected plants compared with healthy and induced plants. -   Also, Evaluate the SAR under field conditions, our results were based on  determination of  chlorophyll pigments, oxidative enzymes and the yield (the dry weight of pods and seeds) for treatments healthy and infected plants.
