CRISPR-Mediated Enhancement of Photosynthetic Efficiency in Oryza sativa
Park J, Williams R, Gupta S
Summary
9.1/10CRISPR editing of two photosynthesis genes in rice achieved 18% better carbon fixation with no yield loss across two seasons.
Key Findings
18% carbon fixation improvement
No yield penalty in 2-season field trials
Targets: RuBisCO activase + SBPase
Original Abstract
Targeted editing of RuBisCO activase and sedoheptulose-1,7-bisphosphatase genes in rice yielded 18% improvement in carbon fixation rates under field conditions. Modified lines showed no yield penalties across two growing seasons in subtropical trials.
Rice
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...
