Re-engineering photorespiratory pathway increases crop yields by 40% [Registered]

Photorespiration is complex, energy-expensive operation that many plants must perform during photosynthesis and which drastically suppresses their yield potential. Researchers from the University of Illinois and US Department of Agriculture ARS (Agriculture Research Service) report in the journal Science that crops engineered with a photorespiratory shortcut are 40% more productive in real-world agronomic conditions.

Researchers synthesize proteins that control enzyme activity [Registered]

“This is the first time that synthetic accessory molecules have been engineered to change the specificity of an enzyme in order to achieve a desired end-product,” said Koide. “In this paper, we demonstrated their efficacy on sugars, but one can envision applications of this concept with enzymes acting on other types of molecules such as lipids and peptides – there are literally hundreds of enzymes currently used in industry and millions that are potentially useful.”
