Carbon dioxide utilization pathway analysis for enhanced crop yield through plant phenotyping

Overview

This research program investigates how targeted regulation of carbon dioxide concentration can enhance crop yield, strengthen plant stems, and increase organic matter content in edible parts such as roots, stems, and leaves. The approach combines controlled CO2 enrichment with phenotyping to understand plant carbon fixation pathways and direct nutrients toward harvestable organs. Initial validation on wheat demonstrated that a directional increase of 5% CO2 concentration can improve yield by 1% (p<0.1) while producing stronger stems. The program aims to expand testing across additional crops to maximize CO2 absorption and develop green feed applications.

Technical specifications

Key research areas:

• Controlled CO2 concentration regulation in growing environments
• Phenotypic observation of stomatal opening and closing in real time
• Analysis of carbon fixation pathways in crop plants
• Methods to concentrate nutrients in crop fruit organs through physiological controls
• Evaluation of stem strength changes under elevated CO2 conditions
• Development of devices for manual intervention in stomatal regulation

Validation approach:

• Determine reasonable CO2 concentration ranges for optimal yield gains
• Identify yield improvement limits across different crop types
• Explore secondary changes from CO2 concentration increases
• Test on multiple crops beyond wheat to broaden applicability

Technology readiness level

The research is at an early-to-intermediate stage with preliminary validation completed on wheat showing measurable yield improvements and stem strengthening effects. The team is seeking partners to expand phenotypic observation capabilities and develop real-time monitoring devices. The experimental timeline is projected at 1 to 2 years for completion. Current needs include collaborators with advanced phenotyping capabilities and funding support to continue the research program.
