Mycorrhizal volatile organic compounds to enhance plant root development and stress resilience
A research-driven biotechnology approach using mycorrhizal fungal volatile organic compounds (VOCs) to promote lateral root formation and whole-plant development by modulating hormonal pathways. Validated in Arabidopsis mutants, this solution targets improved crop performance under stress conditions such as drought, temperature extremes, and elevated CO2.
Overview
This research program investigates how volatile organic compounds (VOCs) emitted by mycorrhizal fungi influence plant hormone balance, driving increased lateral root density and enhanced whole-plant development. By identifying the specific hormonal pathways affected by these fungal VOCs, the work establishes a foundation for novel agricultural biostimulants and crop improvement strategies. The technology has potential applications in improving plant tolerance to environmental stressors including drought, extreme temperatures, and elevated CO2 levels.
Technical specifications
Key features:
- Mycorrhizal VOC blends from three fungal species tested on Arabidopsis hormonal mutants
- Identification of hormonal pathways (including auxin-mediated signaling) responsible for lateral root primordia formation
- Documented increase in lateral root density and overall plant growth under controlled conditions
- Statistical validation using ANOVA and Tukey tests (p < 0.05)
- Planned stress-condition validation across drought, high and low temperature, and varying CO2 environments
- Three-month experimental timeline for stress response characterization
Technology readiness level
The technology is currently at an early-to-mid research stage (TRL 3-4). Laboratory validation has been completed using Arabidopsis mutants impaired in different hormonal pathways, confirming the role of auxins in root primordia formation in response to mycorrhizal VOCs. Future validation under real-world stress conditions is planned but requires equipment and personnel funding. The solution is not yet commercialized and represents an opportunity for collaborative development toward agricultural applications.
