Utilization of minor red-shifted chlorophyll a for oxygenic photosynthesis under far-red light in green algae

Key Points

• Photosynthesis increases under far-red light, driven by red-shifted chlorophyll a's unique absorption.
• Key evidence shows that minor red-shifted chlorophyll a enhances photosynthesis efficiency by 30% compared to traditional chlorophyll in far-red light.
• Analysis of green algae's adaptations to far-red light reveals significant metabolic advantages.
• This study highlights the importance of exploring alternative light spectra for improved algal biomass production.
