Plants, including Cannabis (Cannabis sativa subsp. sativa) host distinct beneficial microbial communities on and inside their tissues, designated the plant microbiota from the moment that they are planted into the soil as seed. They contribute to plant growth promotion, facilitating mineral nutrient uptake, inducing defense resistance against pathogens, higher yield and modulating plant secondary metabolites. Understanding the microbial partnerships with Cannabis has the potential to affect agricultural practices by improving plant fitness and the production yield of cannabinoids. Much less is known about this beneficial Cannabis-microbe partnership, and the complex relationship between the endogenous microbes associated with various tissues of the plant, particularly, the role that cannabis may play in supporting or enhancing them. This review will focus on Cannabis microbiota studies and the effect of endophytes on the elicitation of secondary metabolites production in Cannabis plants. The aim of this review is to shed light on the importance of Cannabis microbiome and how cannabinoid compounds concentration can be stimulated through symbiotic and or mutualistic relationships with endophytes.
