Overexpression of Rubisco activase enhances photosynthesis and plant growth in rice under fluctuating light at high CO2 levels, with up to a 50% faster activation rate.
- Why it matters: Understanding how to improve photosynthetic efficiency under changing environmental conditions is vital for crop productivity amid climate change and rising atmospheric CO2.
- What they did: Researchers created transgenic rice plants with varying Rubisco activase levels and examined their photosynthetic response and growth under fluctuating light at both low and high CO2 concentrations.
- The result: Overexpressing Rubisco activase led to quicker photosynthetic induction, better water use efficiency, and improved growth under fluctuating light at high CO2, supporting its role in future climate resilience.
