  • Team Models Photosynthesis and Finds Room for Improvement

    Teaching crop plants to concentrate carbon dioxide in their leaves could increase photosynthetic efficiency by 60 percent and yields by as much as 40 percent, researchers report in a new study.The team used a computer model to simulate how adding genes from a type of photosynthetic algae known as cyanobacteria might influence photosynthetic efficiency in plants. Cyanobacteria contain small ...

  • Rubisco activase best clue for better photosynthesis in fluctuating light

    Scientists and plant breeders who are aiming to improve food production by improving photosynthesis in crop plants, would make a good choice if they chose to change the composition and concentration of the protein Rubisco activase. In conditions where light intensity changes often and strongly, Rubisco activase is an important limiting factor in boosting the photosynthesis process when light ...

  • Common Pesticide Reduces Food Value of Algae

    SILVER SPRING, Maryland (ENS) - Researchers with the NOAA National Centers for Coastal Ocean Science have identified negative effects of the commonly used herbicide atrazine on phytoplankton, the free-floating algae that form the base of the food chain for aquatic animals. Published in the current issue of the journal 'Pesticide-Biochemistry and Physiology,' the study indicates protein levels ...

  • ARPA-E Provides $300,000 In Third Round Funding For PETROSS Project

    In May of 2016, the DOE's Advanced Research Projects Agency - Energy (ARPA-E) awarded the University of Illinois and the University of Florida $300,000 to continue researching ultra-productive biofuel crops. The research project is called Plants Engineered To Replace Oil in Sugarcane and Sweet Sorghum (PETROSS), and ...

  • Plant diversity: the secret to more nitrogen and carbon in soil

    Plants play a key role in soil carbon (C) and nitrogen (N) accumulation. New research suggests that plant diversity may have an important role to play in stimulating C and N storage in some soils. The findings suggest ways to improve carbon sequestration in grasslands and increase biomass production, for example for biofuel crops on nitrogen limited soils. Soil could be an important carbon sink ...

  • TruLite LED Releases Updated Spectral Output For Their LED Plant Grow Lights

    TruLite LED has officially released their latest update and adjustment to spectral output for their LED plant grow lights. Through continuous research and development of their solid state chip configuration, yields just keep getting better. The use of specific colors in very precise wavelengths in their grow lights is important as research continues. These tweaks are done ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • Scientists find ozone levels already affecting soybean yields

    Current atmospheric ozone levels are already suppressing soybean yields, according to Agricultural Research Service (ARS) scientists and university cooperators studying the effect of global climate change on crops. ARS plant physiologists Don Ort and Carl Bernacchi, molecular biologist Lisa Ainsworth and geneticist Randall Nelson have been working with University of Illinois scientists on a ...

  • Model predicts shifts in carbon absorption by forest canopies

    An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest 'carbon sinks' become net carbon generators instead. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

  • Increasing aridity will disrupt soil nutrient cycles in global drylands

    The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

  • Effects of chemical fertiliser and animal manure on soil health compared

    Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The ...

  • Improving wheat yields for global food security

    With the world’s population set to reach 8.9 billion by 2050, CSIRO scientists are hunting down and exploiting a number of wheat’s key genetic traits in a bid to substantially boost its grain yield. The rate of wheat-yield improvement achievable through conventional plant breeding and genetic engineering alone is not fast enough to compete with a rapidly growing global ...

  • Why seedlings always grow towards the light

    Scientists from the Carnegie Institution at Stanford University and Wageningen University, part of Wageningen UR, have discovered how cells in the stems of seedlings use blue light to grow towards the light. During earlier research it was discovered that the cells in the seedling stems responded to blue light used in the microscope. The scientists have now discovered how the blue light causes ...
