Medicinal Plants
If you grow cannabis, hemp, or just care about soil life, this review shows the roots underground are trading signals with microbes and steering what chemicals show up in the leaves and flowers you actually use.
Most cannabis research looks at the buds and leaves, but this review flips that around to look at what's happening underground. The roots make their own antimicrobial and antioxidant chemicals, team up with specific soil microbes, and send signals upward that can change the chemistry of the whole plant. Scientists think that by studying and even engineering these root systems, growers could boost yields of the plant's most valuable compounds without touching the parts above ground.
Key Findings
Cannabis roots synthesize bioactive compounds with antimicrobial, anti-inflammatory, antioxidant, and cytotoxic properties, distinct from those studied in aerial tissues
Root exudates and endophytic microbes shape rhizosphere microbial networks that support nutrient uptake, stress tolerance, and pathogen resistance
Root-derived phytohormones and signaling molecules may coordinate secondary metabolism between belowground and aboveground tissues, opening a path to root-culture systems for scalable bioactive compound production
chevron_right Technical Summary
Cannabis roots make their own set of antimicrobial and antioxidant compounds and work with soil microbes to help the plant handle stress, and scientists think tuning root biology could boost the valuable chemicals produced in the leaves and flowers above ground.

Cannabis sativa L. roots have been less studied than aboveground organs, despite their key role in plant physiology, metabolism, and interactions with biotic and abiotic factors. Metabolomic and ph...

Cannabis is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis. Al...
