Wheat rust once spurred the Green Revolution, the huge increase in crop yields that started in the1940s.

Some scientists believe, for instance, that crop yields decline 10 percent for each degree rise in temperature.

Virus resistance makes plants less susceptible to diseases caused by such viruses, resulting in higher crop yields.
