Breakthrough could help address growing demand for the staple that already provides a fifth of global caloric intake.
An international team of scientists has identified a gene that can prevent some of the most significant wheat diseases—creating the potential to save more than a billion dollars in lost production in Australia each year.

The findingsshould have wide-reaching ramifications, with wheat already providing a fifth of global caloric intake and set to spike in the next 50 years.
A gene that can prevent some of the most important wheat diseases has been identified—creating the potential to save more than a billion dollars in lost production in Australia each year.
In a global collaboration including the University of Sydney’s Plant Breeding Institute (PBI), the CSIRO, CIMMYT (Mexico), University of Newcastle, Chinese Academy of Sciences and the Norwegian University of Life Sciences, the gene Lr67 has been identified as providing resistance to three of the most important wheat rust diseases, along with powdery mildew, a significant disease in Norway.
The findings, published today in Nature Genetics, should have wide-reaching ramifications, with wheat already providing a fifth of global caloric intake and set to spike in the next 50 years.
