  • 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 ...

  • Biofuel from Algae, Six Decades of Photosynthesis Research at UREM 2015 Conference, Day 3

    Bioethanol may be successfully produced from genetically engineered algae, carbon dioxide and sunlight, Kerstin Baier of Algenol Biofuel Germany told the Umeå Renewable Energy Meeting on its third and final day 27 March. In fact, 4,000 photo bioreactors taking up two acres of land were turning out the very thing at the company’s ...

  • Q&A: A plant lab in the palm of your hand

    PhotosynQ, a project based at the University of Michigan in the United States, aims to help plant scientists around the world gather data through a cheap hand-held device called MultispeQ for scanning plant material.  By connecting the device to a smartphone, researchers can use it to collect information about how efficiently a plant photosynthesises, for example, as well ...

  • 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 ...


  • NREL produces ethylene via photosynthesis

    Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have demonstrated a better way to use photosynthesis to produce ethylene, a breakthrough that could change the way materials, chemicals, and transportation fuels are made, and help clean the air. NREL scientists introduced a gene into a cyanobacterium and demonstrated that the organism remained stable ...

  • Latest FastOcean Sensor used at photosynthesis algorithm evaluation workshop

    Dr Kevin Oxborough participated in a workshop at the NIOZ labs in Yerseke, The Netherlands. The aim of the workshop was to validate a recently published algorithm (Oxborough et al. 2012, Limnology and Oceanography: Methods) that permits accurate estimates of the concentration of PSII reaction centres from active fluorometers. ...

  • Pilot plant Photanol process operational

    Photanol represents a process in which blue green algae combine photosynthesis with fermentation to convert CO2 under the influence of light in organic products e.g. ethanol, ethylene or lactic acid. After the “proof of concept” was delivered financial government support was obtained to build a pilot plant. This pilot was designed ...

  • 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 ...

  • 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 ...

  • Is Algae the new green?

    Algae, one of the most abundant and easily cultured organisms on the planet, has a versatile range of uses in the environmental sector. From treating wastewater to providing bio-fuels, this simple organism may be the answer to several environmental problems. Algae are a large and diverse group of simple photosynthetic organisms with approximately 65,000 different species around the ...

  • 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 ...
