Uncovering the mystery of a major threat to wheat
Date:6/1/2010

This press release is available in Spanish.

Agricultural Research Service (ARS) scientists have solved a longstanding mystery as to why a pathogen that threatens the world's wheat supply can be so adaptable, diverse and virulent. It is because the fungus that causes the wheat disease called stripe rust may use sexual recombination to adapt to resistant varieties of wheat.

ARS plant pathologist Yue Jin and his colleagues Les Szabo and Marty Carson at the agency's Cereal Disease Laboratory at St. Paul, Minn., have shown for the first time that stripe rust, caused by Puccinia striiformis, is capable of sexually reproducing on the leaves of an alternate host called barberry, a common ornamental. The fungus also goes through asexual mutation. But sexual recombination offers an advantage because it promotes rapid reshuffling of virulence gene combinations and produces a genetic mix more likely to pass along traits that improve the chances for survival.

Barberry (Berberis spp) is already controlled in areas where wheat is threatened by stem rust, caused by another fungal pathogen. But the work by the ARS team is expected to lead to better control of barberry in areas like the Pacific Northwest, where cool temperatures during most of the wheat growing season make stripe rust a particular threat.

The researchers suspended wheat straw infected with the stripe rust pathogen over barberry plants and found that fungal spores from the wheat infected the barberry. They also took infected barberry leaves, treated them to promote the release of spores, and exposed them to wheat. Tests confirmed that the wheat plants were infected within about 10 days.

The researchers began the study last year after finding infected leaves on barberry plants at two sites on the University of Minnesota campus. They initially thought the symptoms were a sign t
