Rust research breakthrough announced

For the first time, scientists have isolated genes that show major resistance to stripe rust.

Researchers working together at several locations around the world have cloned the rust-resistance genes Yr7, Yr5 and YrSP.

It’s hoped these genes can next be used in wheat-breeding programs to help battle stripe or yellow rust. The disease’s ability to adapt to several environments and different climates have made control difficult.

“We’ve cloned the first major resistant genes against this fungal pathogen,” Peng Zhang, the study’s co-author and University of Sydney scientist, told the Chinese news agency Xinhau.
