NFs can improve the nutrient use efficiency about threefolds and improve the crop productivity by promoting seed germination, seedling growth, nitrogen metabolism, photosynthetic activity, protein synthesis, antioxidant defense, etc. To capitalize on these advantages, attempts have been made to engineer the C 4 pathway into C 3 rice (Oryza sativa). Plants must adapt to intermittent shading from leaves that are higher in the canopy, or from passing clouds. NPQ turns off, but not quickly enough. Introduction. Whereas improved photosynthetic efficiency has played only a minor role in the remarkable increases in productivity achieved in the last half century, further increases in yield potential will rely in large part on improved photosynthesis. Photosynthesis is an important biochemical reaction that forms the basis of all food chains. However, the crops have some ability to adapt and resist against limited irrigation. This research was supported by the Bill and Melinda Gates Foundation. These two improvements, when combined, have been shown to increase crop productivity by 52 percent in the greenhouse. One strategy to improve photosynthetic yields is to replace a crop plant’s rubisco with a faster enzyme along with a carbon-concentrating mechanism. The work to boost crop productivity comes as concerns about food shortages rise with the world’s population. Plant biologists have bumped up crop productivity by increasing the expression of genes that result in more efficient use of light in photosynthesis, a finding that could be used to help address the world’s future food needs. While much has to be done to improve energy efficiency and waste management of agriculture, crop productivity also has to be increased by 70% to feed a human population growing by 34% and estimated to reach 9.1 billion till 2050 . Photosynthetic capacity and efficiency are bottlenecks to raising productivity and there is strong evidence that increasing photosynthesis will increase crop yields provided that other constraints do … Photosynthesis is the primary determinant of crop yield, and the efficiency by which a crop captures light and converts it into biomass over the growing season is a key determinant of final yield, be that biomass or grain (et al., 2006Long ). “My attitude is that it is very important to have these new technologies on the shelf now because it can take 20 years before such inventions can reach farmer’s fields,” said Long. "It is a powerful tool to assess and guide photosynthetic manipulations and unravel effects that confound the relationship between photosynthetic efficiency and crop performance, "he said. A number of plant features and traits, such as overall plant architecture, leaf structure and morphological features, vascular architecture and flowering time are important determinants of photosynthetic efficiency and hence the overall performance of crop plants. ScienceDaily shares links with sites in the. European Scientist: Scientists increase crop production by 47%. ScienceDaily. More importantly, this study showed up to a 27 percent increase in crop growth in field trials, which is the true test of any crop improvement -- demonstrating that these photosynthetic hacks can boost crop production in real-world growing conditions. January 5, 2021 By: Claire Benjamin . Saturday, January 9 2021 Thus, solar-to-biomass energy conversion efficiency and photosynthetic productivity in high-density cultures can be increased. To achieve this, scientists are analyzing thousands of plants to find out what tweaks to the plant's structure or its cellular machinery could increase production. It’s like having a leak in the system with the valve left open. and performance in a crop context. Modern Farmer: Scientists may found a way to increase crop yield by a bonkers 20% Smithsonian Magazine: New technique could supercharge crop production Popular Science: Scientists tweak plant genes to enhance photosynthesis and increase crop yields Peoria Public Radio (WCBU 89.9): Genetically Modifying Photosynthesis Can … ScienceDaily. Stimulating photosynthetic processes increases productivity and water-use efficiency in the field (Nature Plants) August 21, 2020 / in Plant Science Research Weekly / by Camila Ribeiro Yield potential in crops is determined by the efficiency of photosynthetic rates, which is a critical target for improvement. The Food and Agriculture Organization of the United Nations estimates that food production will need to nearly double by 2050 to meet increasing demand. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign. RIPE aims to increase agricultural production worldwide, particularly to help reduce hunger and poverty in Sub-Saharan Africa and Southeast Asia by sustainably improving the yield of key food crops including soybeans, rice, … 1. Its efficiency is considered a key determinant of crop productivity. Vertical farming: environmental control, light analysis and phytochemical production 3. But plastocyanin has a high affinity for its acceptor protein in the photosystem so it hangs around, failing to shuttle electrons back and forth efficiently. "The mechanism responsible for this additional improvement is not yet clear, but we are continuing to explore this to help us understand why and how this works.". Keywords: Photosynthesis efficiency, abiotic stress, biotic stress, climate change, Multiple Stress Conditions, Crop productivity Important Note : All contributions to this Research Topic must be within the scope of the section and journal to which they … ... which would result in higher crop productivity. (2020, August 10). The RIPE project is an international effort led by the University of Illinois to develop more productive crops by improving photosynthesis -- the natural, sunlight-powered process that all plants use to fix carbon dioxide into sugars that fuel growth, development, and ultimately yield. Saturday, January 9 2021 The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae.

Plants are factories that manufacture yield from light and carbon dioxide -- but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery.
