Revolutionize in Protein Patterns of Different Vicia faba L. Cultivars Infected with Broad bean true mosaic virus under Salicylic Acid Treatments

Abstract: A variety of faba bean cultivars infected with BBTMV showed symptoms as severe mosaic, mottling, crinkling, size decline and malformation. Salicylic Acid (SA) application before inoculation specially 100 μM concentrate was reduced the virus symptoms. In Infected plants under all SA treatments were decreased the viral concentration, percentage of infection and severity of diseases compared with decreasing under BBTMV infection without SA treatments. Increase the level of SA play role important for resistance against BBTMV infection in all faba bean cultivars. Possessions of viral disease with SA application were tested after 21 days from inoculation measured up to healthy control on some protein characters include the quantity of protein bands, molecular weight of band and percentage of the protein band in all diverse faba bean cultivars within this investigation. The results showed that all SA treatments increased all properties of protein patterns. The highest increase was observed when seedling treated by 100 μM (SA and BBTMV) compared with uninfected control. The highest increase of protein contents was observed in infected cv. Sakha1 and lower increase was noticed in cv. Tribe White. In the largest parts of SA applications, the all protein characters were mentioned above an increased includes protein amounts and numbers. Total soluble proteins were accumulated when healthy plants were treated by SA. Stimulation of broad bean cultivars to BBTMV infection under SA application were observed in found many modifications in protein patterns. Probably, the polypeptides accumulation is depending on the SA level. The main purpose of this research was to invistegate the effects of BBTMV and SA treatments on symptoms development, virus concentrations, percentage of infections, disease severity, protein patterns in different broad bean leave cultivars, protein bands numbers, molecular weight bands and percentage of amounts in susceptible and tolerance broad bean cultivars.
