Plants convert sunlight into energy through photosynthesis; however, most of the crops on the planet are affected by photosynthesis, and in order to deal with it, an energy-rich process called photospirace has developed and drastically suppresses their yield potential. Researchers from the University of Illinois and US Department of Agriculture Research for Agriculture report in a journal Science that crops made with photo-patent shortcuts are 40 percent more productive in real agronomic conditions.
"We could feed up to 200 million extra calories lost in photo shoots in the United States every year," said chief researcher Donald Ort, a professor of plant science and plant science at Illinois, Carl R. Woese Institute for Genomic Biology. "Returning even a portion of these calories around the world could be of great help in meeting the food needs of the 21st century – fueled by growing populations and richer high-calorie diets."
This significant study is part of the RIPE, an international research project that is more effective for photoinstrument crop engineering to sustainably increase world food productivity with the support of the Bill & Melinda Gates Foundation, the Food and Agriculture Research Foundation (FFAR) and Department for International Development of the Government of Great Britain (DFID).
Photosynthesis uses the enzyme Rubisco – the brightest energy of the planet – the sun's light, to convert carbon dioxide and water into sugars that trigger growth and yield of plants. During the millennium, Rubisco has become the victim of his own success, creating an atmosphere rich in oxygen. It is not possible to reliably distinguish two molecules, Rubisco grabs oxygen instead of carbon dioxide about 20% of the time, resulting in a plant toxic compound that has to be recycled through the photostatization process.
"Photorespiration is anti-photosynthesis," said chief author Paul South, a research molecular biologist at the RIPE Project in Illinois. "He uses precious energy resources and resources to invest in photosynthesis to produce greater growth and yield."
Photorespiration usually takes a complicated path through three compartments in the plant station. Scientists have devised alternative routes for redirecting the process, dramatically shortening the journey and saving enough resources to boost plant growth by 40 percent. This is the first time that the engineering repair of photosyspheres is tested in real world agronomic conditions.
"Like the Panama Canal, which has been engineering innovation that has increased the efficiency of the trade, these photo-respiratory shortcuts are a testament to plant engineering that proves a unique means of significantly increasing the efficiency of photosynthesis," said RIPE director Stephen Long. University Department of Plant Science and Plant Biology in Illinois.
The team has designed three alternate directions to replace the circular path. To optimize new routes, they designed genetic constructs using various sets of promoters and genes, essentially creating a set of unique path maps. They tested these signs in the 1700 factory to get the best results.
During two years of repetitive field research, they discovered that these engineering plants developed faster, more than 40 percent more biomass was produced and produced, most of which were found in 50 percent larger stems.
The team tested their hypotheses in tobacco: an ideal model for crop research because it is easier to change and test crops, but unlike alternative models, it develops leaves and can be tested on the field. Now, teams transfer these findings to increase the yield of soy, bean-black, rice, potatoes, tomatoes and eggplants.
"Rubisco has even more trouble with carbon dioxide emissions that become warmer, causing more photo-rays," said coauthor of Amanda Cavanagh, an Illinois researcher working on the RIPE project. "Our goal is to build better facilities that today can use the heat and the future to help farmers with the technology they need to feed the world."
Although it will probably take more than ten years to turn this technology into food crops and achieve regulatory approval, RIPE and its sponsors are committed to ensuring that small farmers, especially in sub-Saharan Africa and Southeast Asia, have free reimbursement. access to all project breaks.
