The most common method to speed up plant growth by farmers is the use of fertilizers, composts, insecticides and so on.
On Thursday, scientists from University of Illinois and U.S. Department of Agriculture Agricultural Research Service report in the journal Science the successful tweaking of photosynthesis to enhance more 40 per cent in growth of plants, a process hindered by photorespiration.
Dr Paul South, a molecular biologist at the US Department of Agriculture who led the international team responsible for study in the journal Science refers to photorespiration as an anti-photosynthesis which costs the plant precious energy and resources that it could have invested in photosynthesis to produce more growth and flourish.
The scientists confirmed their hypothesis using tobacco plant, which grows 40 per cent larger. Same method is being conducted on edible food plants.
Professor Donald Ort, a special investigator from the University of Illinois said on photorespiration that, “We could feed up to 200 million additional people with the calories lost to photorespiration in the Midwestern U.S. each year,” he also said, “Reclaiming even a portion of these calories across the world would go a long way to meeting the 21st century’s rapidly expanding food demands – driven by population growth and more affluent high-calorie diets”.
