Stem rust of wheat was responsible for massive epidemics on wheat during the early 20th Century in North America. In the mid-1950s, wheat breeders developed wheat that had genetic resistance to the disease, making it all but disappear. Despite this success, a new, virulent strain of wheat stem rust, Ug99, evolved in Uganda and has already spread into Kenya, Ethiopia and Yemen, with the potential to spread into Pakistan, India, and China, and eventually North America.
"This new race could attack wheat varieties in many countries and could virtually overcome most of the wheat resistant varieties around the globe," said David Marshall, research leader with the USDA-ARS, Raleigh, NC.
According to Marshall, if this new strain were to reach regions at risk, it could create epidemics more severe than farmers have encountered in decades and destroy farmers' harvests in wheat-producing areas worldwide.
New information on the research being done nationally and internationally to combat this disease, including with the Global Rust Initiative, will be addressed during the "Stem Rust: A Threat to Global Wheat Production" symposium on August 1 from 8:30 to 11:30 a.m. The symposium will present the latest on new sources for global resistance to stem rust, details on how the disease is mutating, and what’s in store for North America, including information on how the disease affects wheat grown in the U.S. and Canada.
The symposium will be held during the joint meeting of The American Phytopathological Society (APS) and the Society of Nematologists (SON). The meeting will take place July 28 - August 1, 2007, at the Town and Country Resort and Convention Center, in San Diego, Calif.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
