In 2005 and 2006, greenhouse studies at CDL and field studies in both Kenya and Ethiopia showed that Ug99 had overcome most of the known stem rust resistance genes deployed in wheat cultivars over the years.
Stem rust, caused by the fungus Puccinia graminis sp.
Borlaug, founder of the "Green Revolution," which was responsible for outstanding yield increases in wheat and other major crops in the mid- 1900s, believes that this new mutant strain of stem rust is the most serious threat to wheat and barley crops in 50 years.
This would allow us to track the movement of these rusts worldwide and to immediately recognize types of rust new to this country," Szabo says.
Department of Defense--along with many previous years of research on rust taxonomy--enabled Szabo to develop the first detection test so quickly.
Until recently, plant pathologists could identify only one species of rust fungus attacking the leaves of both wheat and rye plants.
