Abstract: Plant diseases caused by viruses account for an economic loss of about more than 30 billion US dollars a year. Endophytes are the future probiotics for plant health with great potential as biocontrol agents against plant viruses. Arbuscular mycorrhizal fungi and Piriformospora indica are the widely exploited fungal endophytes for management of plant viruses. Biocontrol activity of many other fungal endophytes are reported against viruses, viz., Beauveria bassiana, Trichoderma harzianum and Metarhizium anisopliae. Biocontrol activity of many bacterial endophytes are also reported against viruses viz.,Pantoea agglomeransand Paenibacilluspasadenensis. A continued research pipeline consisting of screening, in vitro and in vivo testing, biomass production and commercialization of endophytes as biocontrol agents can contribute to sustainable agriculture.
Keywords: Endophyte, mycorrhiza, Piriformospora indica, plant viruses
