生物探索推荐英文原文报道: Soybean Genetic Treasure Trove Found in Swedish Village The first screening by U.S. Department of Agriculture (USDA) scientists of the American ancestors of soybeans for tolerance to ozone and other stresses had an eye-opening result: The world superstars of stress resistance hailed from a little village in far northern Sweden, called Fiskeby. The screeners, geneticist Tommy Carter and plant physiologist Kent Burkey, are with the Agricultural Research Service (ARS) in Raleigh, NC. Carter works in the ARS Soybean and Nitrogen Fixation Research Unit, and Burkey is in the agency's Plant Science Research Unit. ARS is USDA's principal intramural scientific research agency. Pictured: ARS geneticist Tommy Carter (right) and ARS plant physiologist Kent Burkey have found that Fiskeby soybeans from northern Sweden have outstanding tolerance for salt, high levels of ozone, drought, iron deficiency and commonly toxic levels of soil aluminum. After analyzing thousands of soybean types to generate the family tree of North American soybeans, Carter found 30 ancestors, which together account for 92 percent of the genetic material in North American soybeans. He screened these ancestors first for salt tolerance. Two lines of vegetable soybeans, Fiskeby 840-7-3 and Fiskeby III, were the most salt tolerant. Carter screened for aluminum tolerance, and again the Fiskeby plants stood out -- and the same thing happened when he screened for tolerance to drought and high ozone levels. The Fiskeby plants also were found to be resistant to iron deficiency and toxic soil aluminum. The scientists searched breeder pedigree records and found that only a few U.S. cultivars trace their ancestry to the Fiskeby stress-tolerant types. This indicates that there is great potential to increase tolerance to ozone and other stresses in North American soybeans by adding genes from Fiskeby. Burkey, Carter and Jim Orf, a geneticist at the University of Minnesota at St. Paul, have crossed Fiskeby III with ozone-susceptible Mandarin Ottawa soybeans and developed 240 breeding lines from the offspring. With the help of funding from the United Soybean Board of Chesterfield, Mo., the team is mapping the genes in these lines to see which are connected to resistance to ozone and the other stresses. The Swedish soybeans appear to have an even more pronounced resistance to ozone than to the other stresses. Understanding the ozone effect may be key to unraveling the secrets of the broad stress resistance of the Swedish soybeans. 北美大豆耐臭氧和其他压力的能力将有巨大的提升潜力。结果发现只有几种美国大豆品种的祖先是耐压的“菲斯克比”大豆。伯基、另外,“菲斯克比”大豆的表现也非常突出。“菲斯克比”大豆的表现非常突出, |
