ST. PAUL (AP) Senator Amy Klobuchar says she'll fight to preserve funding for plant disease research at the University of Minnesota. The Minnesota Democrat toured the USDA's Cereal Rust Laboratory on the St. Paul campus. Despite a new type of wheat rust that threatens the world's food crops, the Bush administration wants to cut over $300,000 from the laboratory's research into the fungus, which is spreading from Africa to the Middle East. Klobuchar says she and others succeeded in getting funding restored last year and she's working to do that again. Klobuchar says the new plant disease affects Americans because anything that reduces the world's food supply pushes up food prices. The laboratory is one of only three in the world doing this kind of research.
