Efforts to halt a fungus that deprives about 60 million people a year of food have led Purdue University scientists to discover the molecular machinery that enables the pathogen to blast its way into rice plants.
The fungus, Magnaporthe grisea, which is known as rice blast fungus, is the most deadly of the pathogens that attack rice, reducing yields by as much as 75 percent in infected areas. Learning how the fungus tricks rices natural defenses against pathogens to penetrate the plant is an important part of controlling the disease, said Jin-Rong Xu, a Purdue molecular biologist.
Xu, Xinhua Zhao, Yangseon Kim and Gyungsoon Park, all of Purdues Department of Botany and Plant Pathology, found that an enzyme is a key player in coordinating the fungus attack. The enzyme, called a pathogenicity mitogen-activated protein (MAP) kinase, flips the switch that starts the cellular communication necessary to launch the fungal invasion that kills rice plants or causes loss of grain.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
