Canadian-led study will help scientists identify key genomic regions in canola, other food plants

What allows certain plants to survive freezing and thrive in the Canadian climate, while others are sensitive to the slightest drop in temperature? Those that flourish activate specific genes at just the right time -- but the way gene activation is controlled remains poorly understood.

Natural growth regulator found to increase or decrease growth, depending on application

COPENHAGEN, DENMARK—Natural products marketed as plant growth enhancers are becoming increasingly sought-after. Many of these products, typically produced by small companies with limited research capabilities, have not been tested in farm trials, nor have claims about product effectiveness been documented by scientific data. Researchers from the University of Copenhagen investigated the growth regulatory effect of Tea Seed Powder (TSP), a saponin-rich waste product from tea seed (Camellia sp.) oil production. The results of research appeared in the HortScience.

Humans Can Unwittingly Bring Alien Plant Species to Svalbard PDF Print E-mail
Wednesday, 23 November 2011 05:08

New research shows that humans can unwittingly bring alien plant species to Svalbard. Increased travel activity and expected temperature increases over the next decades, may make the establishment of new plant species in the archipelago's vulnerable ecosystem possible. This calls for a closer look at the management policy for travelling to Svalbard.

Plants moderate climate warming PDF Print E-mail
Sunday, 28 April 2013 22:01

As temperatures warm, plants release gases that help form clouds and cool the atmosphere, according to research from IIASA and the University of Helsinki.

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling effect on the atmosphere.

Making Do with More: Joint BioEnergy Institute Researchers Engineer Plant Cell Walls to Boost Sugar Yields for Biofuels PDF Print E-mail
Sunday, 31 March 2013 12:43

When blessed with a resource in overwhelming abundance it’s generally a good idea to make valuable use of that resource. Lignocellulosic biomass is the most abundant organic material on Earth. For thousands of years it has been used as animal feed, and for the past two centuries has been a staple of the paper industry. This abundant resource, however, could also supply the sugars needed to produce advanced biofuels that can supplement or replace fossil fuels, providing several key technical challenges are met. One of these challenges is finding ways to more cost-effectively extract those sugars. Major steps towards achieving this breakthrough are being taken by researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI).

Findings could lead to high-yield crops that gather light more efficiently and make better use of farmland.

LA JOLLA, CA ---- Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight. Whether a forest or a farm, where plants grow a battle wages for the sun's rays.

Stanford, CA— Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world's most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant's brain.

Salt-tolerant crops show higher capacity for carbon fixation PDF Print E-mail

Tomato, watermelon prove most efficient at CO2 accumulation

MURCIA, SPAIN—Salt can have drastic effects on the growth and yield of horticultural crops; studies have estimated that salinity renders an about one-third of the world's irrigated land unsuitable for crop production. Imbalances in soil salinity can cause ion toxicity, osmotic stress, mineral deficiencies, and drastic physiological and biochemical changes in plants. Salt stress can even cause plants to adjust their water usage—to conserve water, some plants close their stomata, thus restricting the entry of carbon dioxide (CO2) into the leaf and reducing photosynthesis.

New grass family tree reveals C4 photosynthesis is an evolutionary 1-way street 

or grain-fed turkey this Thanksgiving, give thanks to the grasses — a family of plants that includes wheat, oats, corn and rice. Some grasses, such as corn and sugar cane, have evolved a unique way of harvesting energy from the sun that's more efficient in hot, arid conditions. A new grass family tree reveals how this mode of photosynthesis came to be.

Forests not keeping pace with climate change PDF Print E-mail
Tuesday, 01 November 2011 05:58

DURHAM, N.C. -- More than half of eastern U.S. tree species examined in a massive new Duke University-led study aren't adapting to climate change as quickly or consistently as predicted.

"Many models have suggested that trees will migrate rapidly to higher latitudes and elevations in response to warming temperatures, but evidence for a consistent, climate-driven northward migration is essentially absent in this large analysis," says James S. Clark, H.L. Blomquist Professor of Environment at Duke's Nicholas School of the Environment.
