Researchers learn how pathogen causes speck disease

(PhysOrg.com) -- Researchers have discovered how the structure of a protein allows a certain bacteria to interfere with the tomato plant's immune system, causing bacterial speck disease.

Missing link in plant immunity identified

After a 30-year search, scientists have uncovered how an enzyme critical to plants' rapid immune response against microbes is activated.

Designer wheat fails anti-aphid field test

The scientific quest for pest-resistant crops suffered a blow Thursday when disappointed British researchers announced their designer wheat failed to repel aphids in the field.

Bioluminescent technology for easy tracking of GMO

It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central's open access journal BMC Biotechnology shows ...

Bacteria pitted against fungi to protect wheat and barley

(Phys.org)—Soil-dwelling bacteria that depend on wheat and barley roots for their "room and board" could soon prove themselves helpful to the plants in return. U.S. Department of Agriculture (USDA) scientists in Pullman, ...

Plants give up some deep secrets of drought resistance

In a study that promises to fill in the fine details of the plant world's blueprint for surviving drought, a team of Wisconsin researchers has identified in living plants the set of proteins that help them withstand water ...

Examining rice genes for rice blast resistance

U.S. Department of Agriculture (USDA) 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 ...

Wheat genome blueprint accelerates innovation

"The wheat blueprint will enable us to decipher the genetic basis of important traits in wheat, such as genes responsible for resistance to fungal diseases and pests. That is the disruptive part. What took years to do before ...

Mystery of nematode pest-resistant soybeans cracked

For 50 years, the world's soybean crop has depended on the use of cyst nematode resistant varieties of beans, but no one knew how these plants fought off the nematode pests. Now, the secrets of resistant soybean plants are ...
