Wild Potato's Gene May Protect Vulnerable Spuds

Washington, D.C. (August 9, 2004) - The potato sometimes falls
victim to its worst enemy, a disease called late blight. But Agricultural
Isolated from a wild Mexican potato, Solanum bulbocastanum,
the novel Sbul1 gene may work in concert with other genes to boost the ability
of popular, domesticated S. tuberosum tubers to shrug off attacks by the
A team led by ARS plant physiologist William R. Belknap at the
Helgeson had fused S. bulbocastanum with S. tuberosum potatoes. Then, ARS researchers at Aberdeen, Idaho, used samples of these potatoes to develop new, experimental tubers that they provided to Belknap.
Each time they crossed, or "hybridized," the Wisconsin potatoes
At Albany, researchers isolated and copied the Sbul1 gene from
