Abstract
AbstractCurrently, crop production is at risk due to the global warming effect with increased biotic and abiotic stresses. Viral diseases of plants cause enormous economic losses particularly in the tropics and semi-tropics. Assessments of losses as a result of pest or pathogen attack in crop plants are mostly lacking. In particular, viral diseases cause serious economic losses destroying crops and reducing agronomic productivity, they become the limiting factor production of both open field and under greenhouse cultivation systems. This is because plant viruses are obligate parasites and require living tissue for their multiplication and spread. Therefore, they are able to interfere with plant metabolism and compete for host plant resources, so determining a decrease of plant growth and productivity. Many diverse approaches have been tried to minimize the losses caused by these diseases. In such a scenario, it is necessary to introduce new strategies for controlling plant viruses and parasites in order to help maintain ecosystems and to boost sustainable agriculture. The work on virucidal activity of endophytes against plant viruses is very negligible and absent. Therefore, based on available literature and experience, we have formulated the protocols for the testing of plant endophytes against plant viruses.Key wordsEndophyteVirusScreeningIsolatesMicrobes
