By boosting the expression of three genes involved in NPQ, they showed that NPQ turned off more quickly, and the efficiency of photosynthesis in the shade was higher. Whether this greater photosynthetic efficiency during shading events would affect productivity was evaluated under field conditions in a randomized block … Photosynthesis is an important biochemical reaction that forms the basis of all food chains. ScienceDaily. "Like a factory line, plants are only as fast as their slowest machines," said Patricia Lopez-Calcagno, a postdoctoral researcher at Essex, who led this work for the RIPE project. The work to boost crop productivity comes as concerns about food shortages rise with the world’s population. "We have identified some steps that are slower, and what we're doing is enabling these plants to build more machines to speed up these slower steps in photosynthesis.". However, the crops have some ability to adapt and resist against limited irrigation. Users can select specific wavelengths to elicit targeted photomorphogenic, ... McCree KJ (1972) The action spectrum absorptance and quantum yield of photosynthesis in crop plants. Photosynthetic hacks can boost crop yield, conserve water. This research program, known as Realizing Increased Photosynthetic Efficiency or RIPE, is being led by the University of Illinois. Photosynthesis is an important biochemical reaction that forms the basis of all food chains. Some limitations and adverse effects of NFs have also been reported. Congratulations to Mary Blackburn on winning the National Extension Association of Family and Consumer Sciences Hal… https://t.co/4XBCXsQvEX, Since its founding in 1915, Forestry Camp has been canceled only twice, during both World Wars. When there is too much sunlight, the photosynthetic machinery in chloroplasts can be damaged, so plants need photoprotection. Crop breeding has sustained steady improvements in yield to keep pace with population growth increases. RIPE is supported by the Bill & Melinda Gates Foundation, the U.S. Foundation for Food and Agriculture Research (FFAR), and the U.K. Government's Department for International Development (DFID). The C 4 photosynthetic pathway is a CO 2 -concentrating mechanism that generally enables C 4 plants to achieve greater efficiency in their use of light, nitrogen, and water than C 3 plants. This review attempts to develop a mechanistic understanding of the effects of N on crop biomass accumulation by elucidating quantitative relationships among leaf N content, CO 2 assimilation rate, and crop radiation use efficiency. The researchers described their findings in a paper published today in the journal Science. Overall, canopy architecture significantly affected canopy photosynthetic efficiency and water-use efficiency, suggesting that optimizing canopy structures can contribute to yield enhancement in crops. 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. Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign. Yields of the world’s major staple crops have not been increasing fast enough to meet this projected need. Maureen R. Hanson, Molecular Biology and Genetics, is focusing on an enzyme that limits the efficiency of In this work, the TLA concept was applied in high-density tobacco canopies. Photosynthesis is the basis of primary productivity on the planet. Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign. Light-emitting diode (LED) technology is paving the way to increase crop production efficiency with electric lamps. Flag leaves could help top off photosynthetic performance in rice. Plants contain the green pigment chlorophyll and they require light energy from the sun to photosynthesize and to grow. Introduction Plants greatly … Its efficiency is considered a key determinant of crop productivity. A team of scientists from the University of Essex has boosted crop productivity by 27 percent by resolving two bottlenecks in photosynthesis–the process whereby plants fix carbon dioxide into the sugars that fuel crop growth. This research was supported by the Bill and Melinda Gates Foundation. ANRV410-PP61-11 ARI 8 April 2010 0:47 Improving Photosynthetic Efficiency for Greater Yield Xin-Guang Zhu,1,2,3 Stephen P.

January 5, 2021 By: Claire Benjamin . Its efficiency is considered a key determinant of crop productivity. The Food and Agriculture Organization of the United Nations estimates that food production will need to nearly double by 2050 to meet increasing demand. “When there is too much sunlight, it’s like pressure building up,” said Niyogi. 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. 1. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. 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. NPQ turns off, but not quickly enough. ... which would result in higher crop productivity. 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 … The project's second breakthrough, also published in Science, created a shortcut in how plants deal with a glitch in photosynthesis to boost productivity by 20 to 40 percent. ScienceDaily shares links with sites in the. Crop production is strongly dependent on the photosynthetic rates. These two improvements, when combined, have been shown to increase crop productivity by 52 percent in the greenhouse. Nature Plants. Photosynthetic efficiency and biomass productivity in rice largely decreased at cool temperatures (Nagai and Makino, 2009), and rice yield in northern regions of Japan is limited by low biomass accumulation in cool climates between spring and early summer. The EC-funded project GAIN4CROPS is developing novel disruptive technologies to overcome one of the main constraints on photosynthetic efficiency: photorespiration, a process that reduces CO2 assimilation efficiency, and thus biomass yield and agricultural productivity. Hanson and her lab are producing vectors that will install a novel cyanobacterial-based, carbon-concentrating mechanism into a chloroplast, and they are providing the necessary molecular machinery to facilitate its operation. Therefore, in this study, the relationship between water, crop production, photosynthesis, crop transpiration, crop growth, crop yields and water use efficiency have been discussed under limited irrigation conditions. Greenhouse crop production: canopy photosynthesis, growth modelling, and spectrum conversion film 2. This establishes the viability of a functional nanomaterial to augment photosynthesis as a route to increased crop productivity. “NPQ turns on and gets rid of the excess energy safely. Effects of N in crops are profound, but much understanding of crop growth responses to N is empirical. These two improvements, when combined, have been shown to increase crop productivity by 52 percent in the greenhouse. April 24, 2020. Photosynthesis in this leaf provides the majority of The flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Half of crop photosynthesis occurs in the shade, so any improvement in speeding up recovery from photoprotection could have a big benefit, the researchers said. 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 . "Our modeling suggests that stacking this breakthrough with two previous discoveries from the RIPE project could result in additive yield gains totaling as much as 50 to 60 percent in food crops.". We assert that increasing the efficiency and productivity of photosynthesis in crop plants will be essential if this grand challenge is to be met. Questions? Photosynthesis is the basis of plant growth, and improving photosynthesis can contribute toward greater food security in the coming decades as world population increases. Saturday, January 9 2021

These findings represent a breakthrough in bioengineering plants to achieve efficient photosynthesis and increase crop productivity under normal and heat-stress conditions. In higher plants, photosynthetically active radiation (PAR), the fraction of sunlight with wavelengths from 400 to 700 nm is harvested by the photosynthetic pigments of photosystems PSI and PSII. Here, we explore an array of prospective redesigns of plant systems at various scales, all aimed at increasing crop yields through improved photosynthetic efficiency and performance. Note: Content may be edited for style and length. 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, … A factory's productivity decreases when supplies, transportation channels, and reliable machinery are limited. However, photosynthetic efficiency remains standing as a determinant of yield potential with the improvement capacity to double crop productivity (1–3, 5, 6). Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign. Scientists engineered plants with a photosynthesis “shortcut” to increase crop production by up to 40%, according to a research article published in Science journal. “If we don’t do it now, we won’t have this solution when we need it.”. Overall, canopy architecture significantly affected canopy photosynthetic efficiency and water-use efficiency, suggesting that optimizing canopy structures can contribute to yield enhancement in crops. Here we examine inefficiencies in photosynthetic energy transduction in crops from light interception to The photosynthetic efficiency in most crops is less than 2% and even a small increase in this has potential to improve biomass and yield. Light attenuation is an important aspect that influences the overall photosynthetic rate and the accumulation of biomass of plants, particularly cotton (Gossypium hirsutum L.).Thus light quality and light duration play an important role in the productivity of cotton. 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 … The photosynthetic engine can’t work as efficiently.”.

In this study, the team increased crop growth by 27 percent by resolving two constraints: one in the first part of photosynthesis where plants transform light energy into chemical energy and one in the second part where carbon dioxide is fixed into sugars. “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. Inside two photosystems, sunlight is captured and turned into chemical energy that can be used for other processes in photosynthesis. 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. In rice plants, the flag leaf is the last to emerge, indicating the transition from crop growth to grain production. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and the University of Illinois targeted three genes involved in a process plants use to protect themselves from damage when they get more light than they can safely use. Patricia E. López-Calcagno, Kenny L. Brown, Andrew J. Simkin, Stuart J. Fisk, Silvere Vialet-Chabrand, Tracy Lawson, and Christine A. Raines. The team at Dr Sayre’s lab has also produced several studies that suggest that capturing CO 2 by algae The maximum yield attainable from a crop has been termed yield Introduction. "Photosynthetic hacks can boost crop yield, conserve water." Realizing Increased Photosynthetic Efficiency (RIPE) is a translational research project that is genetically engineering plants to photosynthesize more efficiently to increase crop yields. "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 transport protein called plastocyanin moves electrons into the photosystem to fuel this process. Plants must adapt to intermittent shading from leaves that are higher in the canopy, or from passing clouds.
