Ug99 is a strain of wheat stem rust that was first identified in Uganda
in 1998 (and named in 1999). By 2001, Ug99 began appearing in fields in
Kenya; in Ethiopia by 2003; Sudan and Yemen by 2006; and Iran a year
later. It now plagues wheat plants in nine African and Middle Eastern
countries. Should the pathogen establish a global presence, 90 percent
of wheat varieties could succumb, with whole crops flopping over and
rotting within weeks or months of infection. The annual global harvest
of some 700 million tons of wheat would be decimated...
University of Minnesota’s Anderson says GM corn and soybeans may have
received more acceptance because they’re often processed or fed to
animals, whereas most wheat enters the human food stream. Some consumers
fear that tinkering with crop genomes could reduce the nutritive value
of food, introduce toxins, increase the use of pesticides, or propel our
already heavily-processed diets further away from what nature provided...
Nevertheless, GM wheat may still make its debut. In 2010, Monsanto
announced that it was re-entering the field of biotech wheat and would
work to genetically engineer crops that are higher yielding, stress
tolerant, or herbicide resistant...
Wheat growers are also starting to come around to the idea of
cultivating GM plants. Several years ago, the National Association of
Wheat Growers and US Wheat Associates expressed their support of biotech
wheat. “We just have to prepare ourselves for a future where GM crops
are more accepted,” Wulff says.
