Researchers in the US have genetically engineered a way of shortcutting photosynthesis to increase the size of tobacco plants by up to 40%.
They say the development could be applied to increase the yield of other important crops, as a way of boosting food productivity for a growing population in the face of climate change. The research was published today in the journal Science.
Estimates suggest that, compared with 2005, worldwide demands on the agricultural system will increase by 60 to 120% by the middle of the century. However, crop yields are currently only increasing by less than 2% per year, suggesting there will be a significant shortfall in meeting this demand…[READ MORE]
