Plant Microbiome

The plant microbiome refers to the community of microorganisms—bacteria, fungi, and archaea—that colonize cannabis tissues and growing media. Rather than a single terpene, the microbiome is an ecological system that influences secondary metabolite production, including terpene synthesis and expression. Healthy microbial communities in soil and rhizosphere are commonly associated with enhanced nutrient uptake and plant vigor. Breeders and cultivators working in controlled environments increasingly document how microbiome composition correlates with terpene profiles and cannabinoid ratios across genetic lines. Understanding microbiome dynamics has become relevant to phenotype stability and consistency in cannabis genetics research.

Breeders studying microbiome effects use this knowledge to standardize cultivation conditions and identify how specific genetic lines respond to microbial inoculants or soil ecology. Microbiome management is being integrated into breeding protocols to assess whether terpene and cannabinoid expression is genetically fixed or environmentally modulated.
