Microbial Genetics

Microbial genetics refers to the study of genetic material and hereditary traits in microorganisms—bacteria, fungi, and other microbes—that interact with cannabis plants during cultivation and post-harvest processing. In cannabis breeding and cultivation contexts, microbial genetics becomes relevant when considering how beneficial microbes (mycorrhizae, endophytes, rhizobia) colonize plant tissues and potentially influence secondary metabolite production, including terpene profiles. The genetic diversity of microbial communities in growing media and on plant surfaces can vary considerably based on environmental conditions, substrate composition, and agricultural practices. Breeders and cultivators increasingly recognize microbial ecology as a factor in phenotypic expression, though direct genetic transfer from microbes to cannabis plants remains a complex and evolving area of research.

Some breeders and cultivation researchers explore microbial inoculants and managed microbiomes as tools to stabilize or enhance phenotypic traits across generations. Understanding microbial genetics helps explain variability in terpene expression and plant vigor that may not be solely attributable to cannabis nuclear genetics.
