CRISPR-Mediated Enhancement of Photosynthetic Efficiency in Oryza sativa

More efficient rice plants could mean higher food production on the same farmland — helping feed more people as climate pressures on agriculture intensify.
Researchers tweaked two key genes in rice that control how the plant converts sunlight and CO2 into food energy. The edited plants were significantly better at capturing carbon from the air — about 18% more efficient. Crucially, farmers wouldn't lose any harvest yield, making this a practical step toward more productive crops.
Key Findings
18% improvement in carbon fixation rates achieved under real field conditions
No yield penalties observed across two full growing seasons in subtropical trials
Two genes were targeted: one involved in activating the plant's main carbon-capturing enzyme, and one involved in recycling carbon intermediates
chevron_right Technical Summary
Scientists used CRISPR gene editing to make rice plants photosynthesize more efficiently, resulting in an 18% boost in carbon fixation without any loss in crop yield across two growing seasons.

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
