Antiviral potential of crude extracts from two Streptomyces spp. against Cucumber Mosaic Virus infection under greenhouse conditions.

ABSTRACT: Marine actinomycetes are a promising source for developing new antiviral agents for plant diseases, as they produce a wide variety of bioactive compounds. To date, antiviral activity of marine actinomycetes against plant viruses are rare. The present study proceeded to identify and characterize promising antiviral actinomycetes from Red Sea in Hurghada, Egypt, control Cucumber Mosaic Virus (CMV) and, profile the individual chemical components of bioactive crude extracts. Biological and molecular characterization was performed to identify CMV isolate using RT-PCR and coat protein (CP) gene nucleotide sequences analysis. In squash plants, antiviral, CMV optical density, biochemical responses, and resistance genes expression of Streptomyces extracts (SE1 and SE2) were performed against CMV by
