US Department of Agriculture scientists have characterized the molecular mechanism behind some plants' ability to resist rice blast, a fungal disease that affects cereal grain crops such as rice, wheat, rye and barley and can cause yield losses of up to 30 percent. The fungus has been found in 85 countries worldwide, including the United States.

Washington State University scientists have established that a barley plant recognizes an invader and begins to marshal its defenses within five minutes of an attack.
The discovery, along with the scientists' successful cloning of disease-fighting genes and the pathogen signal recognized by the plant, could help to revolutionize the battle against cereal crop enemies, such as stem rust.

Using barley as the raw material for ethanol production results in an additional product -- dried grains for animal feed. But the presence of a fungal pathogen sometimes found in barley can result in a lethal toxin, called mycotoxin, in the animal feed. Now, Virginia Tech and US Department of Agriculture researchers have shown that newly developed transgenic yeast used during fermentation will help modify the mycotoxin in the animal feed product to a less toxic form.

Research, led by the University of Warwick, The Sainsbury Laboratory and Virginia Tech, has sequenced the genome of a plant disease causing organism revealing that it acts like a "stealth bomber of plant pathogens." The research has uncovered the tactics used to sneak past the plant's immune defenses. That same discovery also provides tools for researchers to identify the components of the plant immune system and devise new ways to prevent disease.

Individual kernels of wheat and barley can be quickly evaluated for resistance to a damaging scab disease by using near infrared light technology, according to a US Department of Agriculture study conducted in support of a program to safeguard these valuable grain crops.

By exploiting technology originally used in human genome studies, a public-private partnership program is changing the way in which commercial barley breeding is being conducted. Findings from this four-year research project are highlighted in the latest issue of Business, the quarterly highlights magazine of the Biotechnology and Biological Sciences Research Council.

 | CSIRO researchers have identified wheat and barley lines resistant to Crown Rot -- a disease that costs Australian wheat and barley farmers $79 million in lost yield every year. ...> Full Article |
 | Researchers at the University of Warwick have recovered significant DNA information from a lost form of ancient barley that triumphed for over 3,000 years seeing off: five changes in civilization, water shortages and a much more popular form of barley that produces more grains. This discovery offers a real insight into the couture of ancient farming and could assist the development of new varieties of crops to face today's climate change challenges. ...> Full Article |
 | An international team of scientists has developed salt-tolerant plants using a new type of genetic modification, bringing salt-tolerant cereal crops a step closer to reality. ...> Full Article |
