Photosynthesis, Carbon Fixation & Metabolic Engineering

Photosynthesis, carbon fixation, and metabolic engineering sit at the heart of how plants convert sunlight, water, and carbon dioxide into the energy and biomass that sustain nearly all life on Earth. This field studies the light reactions, the carbon-fixing pathways, and the intricate metabolic networks that determine how efficiently a plant captures and uses energy. It also extends into engineering, where researchers redesign these pathways to boost productivity, improve resource use, and create plants tailored for specific needs. This Photosynthesis, Carbon Fixation & Metabolic Engineering session brings together scientists working to understand and reshape the fundamental chemistry that powers plant growth.

Improving photosynthetic efficiency is widely seen as one of the most promising routes to raising crop yields and meeting global food demand. By dissecting the mechanisms of carbon fixation and engineering metabolic pathways, researchers aim to overcome natural limitations, reduce energy losses, and enhance the conversion of carbon into harvestable product. Delegates at this Plant Biology Conference will explore advances in C3, C4, and CAM photosynthesis, synthetic carbon-capture routes, and strategies for redirecting plant metabolism. By targeting the engine of plant productivity, the field offers transformative potential for those advancing plant metabolic engineering.

This session is designed for biochemists, physiologists, synthetic biologists, bioengineers, and students fascinated by the chemistry of life and its optimization. Participants will encounter cutting-edge research on energy capture, carbon assimilation, and pathway design, with opportunities to connect fundamental biochemistry to applied crop and bioproduct innovation.
