Dubcovsky commented in The Scientist article about his work in using biotechnology to instill resistance to a devastating plant disease, stripe rust, in wheat.
“Wheat is a very important cereal,” says Ravi Singh of Irrigated Bread Wheat Improvement and Rust Research in Mexico. “Twenty percent of [humans'] calories and about the same [percent of] protein are coming from wheat.”
Genetic engineering is a way to breed long-lasting stem rust–resistant wheat varieties and boost wheat yields around the world. But genetically modified foods are being kept off the market by public opposition and regulatory expenses.
The Scientist article, written by Kerry Grens, said a few groups are forging ahead, including Dubcovsky and other researchers who are cloning stripe rust-resistance genes from wheat and other taxa and identify their functions.
