The following is an edited excerpt.
Sr35 has been identified as a gene that enables resistance to a new race, or strain, of stem rust, a disease that is producing large wheat yield losses throughout Africa and Asia and threatening global food security.
Previous resistance genes that had proven effective for fighting the disease for 50 years are ineffective against this new race. Scientists are now looking for new sources of resistance to protect the global wheat crop, which millions of people depend on for food.
By transferring this gene to commercial wheat varieties, wheat breeders will have a distinct advantage in controlling the epidemic, the researchers say.
