Study underscores canned foods' importance to help address IOM Weight of the Nation recommendations
The IOM issued its obesity-prevention report at the Weight of the Nation conference hosted by the CDC. This report included a call to action for increased access to healthy foods (like fruits and vegetables) at retail outlets nationwide. Findings from a new Michigan State University study released today, underscored the critical role that canned fruits and vegetables play in helping Americans increase these intakes, regardless of geography or income level.

Freshwater crayfish found to have substance covering teeth astonishingly similar to human enamel
A team of Israeli and German scientists from Ben-Gurion University of the Negev and the Max Planck Institute of Colloids and Interfaces have found an enamel-like layer in the mandibles of freshwater crayfish, according to an article in Nature Communications.

Ancient tree-ring records from Southwest US suggest today's megafires are truly unusual
Today's mega forest fires of the southwestern U.S. are truly unusual and exceptional in the long-term record, suggests an unprecedented study that examined 1,500 years of ancient tree ring and fire data from two distinct climate periods. Researchers constructed and analyzed a statistical model and found that today's dry, hot climate combined with the past century of human fire suppression is causing megafires, said study co-author and fire anthropologist Christopher Roos, Southern Methodist University, Dallas.

The millennium-old olive trees of the Iberian Peninsula are younger than expected
Northeast Spain is home to olive trees so old that they are known as "millennium-old." A group of scientists have now studied their age. The oldest is to be found in the Catalan region of Montsia and is 627 years old making it one of the oldest olive trees recorded in Europe.

The Plant Cell
Plant growth without light control
Plants are dependent on the sun. Sunlight does not only supply them with energy, but also controls their development steps. So-called photoreceptors activate the processes of germination, leaf development, bud formation, and blossoming in the cells. The light-absorbing component of a photoreceptor may be replaced by a chemically similar synthetic substance. For the first time, the effects on complete plants are now described in the The Plant Cell journal.

Maps of Miscanthus genome offer insight into grass evolution
Miscanthus grasses are used in gardens, burned for heat and energy, and converted into liquid fuels. They also belong to a prominent grass family that includes corn, sorghum and sugarcane. Two new, independently produced chromosome maps of Miscanthus sinensis (an ornamental that likely is a parent of Miscanthus giganteus, a biofuels crop) are a first step toward sequencing the M. sinensis genome. The studies reveal how a new plant species with distinctive traits can arise as a result of chromosome duplications and fusions.

When the soil holds not enough phosphorus
Paula Duque and her research team at the Instituto Gulbenkian de Ciencia have identified a new inorganic phosphate (Pi) transporter in the root cells of the tiny mustard plant Arabidopsis thaliana that acts, crucially, when Pi is scarce. Their findings, published online in the journal New Phytologist, provide insight into how phosphate transport systems may be manipulated in plants to counteract stressful conditions and thus, potentially, lead to improved crop yields.

Secret soil cracks linger, despite surface sealing
Researchers at the University of NSW in Sydney have developed an innovative technique for examining the flow of water through cracks in soil by measuring electrical resistivity. They discovered that even when cracks appear visibly closed on the surface they often remain open underground. They can now detect the exact time when underground cracks close, which will have big implications for agricultural management of water.

Relative reference: Foxtail millet offers clues for assembling the switchgrass genome
The US Department of Energy is interested in the perennial grass switchgrass as a prospective biofuels feedstock, but the plant genome is complex. The DOE Joint Genome Institute has sequenced plant genomes of related candidate bioenergy crops such as sorghum and the model grass Brachypodium but they last shared a common ancestor with switchgrass more than 20 million years ago. The genome of a much closer switchgrass relative -- foxtail millet -- is described in Nature Biotechnology.

Iowa State, Salk researchers make plant protein discovery that could boost bioeconomy
Research groups from Iowa State University and the Salk Institute for Biological Studies have found three proteins involved in the accumulation of fatty acids in plants. The discovery could help plant scientists boost seed oil production in crops. And that could boost the production of biorenewable fuels and chemicals. The discovery has been published by nature.com.
