Microbial Volatile Interactions

Microbial Volatile Interactions (MVIs) describe the exchange of chemical signals between cannabis plants and their associated microbial communities—fungi, bacteria, and other microorganisms in soil and rhizosphere environments. These interactions influence secondary metabolite production, including cannabinoid and terpene profiles, through microbial-derived volatile compounds that trigger plant biochemical responses. Breeders and cultivators increasingly recognize that strain expression is not purely genetic; soil microbiota composition can modulate phenotypic outcomes. Research into MVIs remains emerging, with lineage records and cultivation notes documenting variable terpene and cannabinoid ratios under different microbial inoculants. Understanding these dynamics is relevant to reproducible cultivation and genetic preservation strategies.

Breeders working with microbial-enhanced cultivation systems document shifts in secondary metabolite expression across generations, informing strain stabilization protocols. Seed banks and preservation programs increasingly account for microbial association when characterizing strain genetics, recognizing that microbiota legacy may influence offspring phenotypes.
