Washington, D.C. (August 12, 2004) - Rice plants could soon be getting their own version of "caller ID." Agricultural Research Service scientists are providing plants of this important world crop with the genetic tools needed to recognize and identify incoming attacks from the damaging pathogen known as rice blast. The fungus, Magnaporthe grisea, causes rice yield losses of up 30 percent each year worldwide.
Two-thirds of the global population relies on rice. And while
According to ARS chemist Sally Leong, blast is so adaptable that
