USDA Researchers Isolate Gene Triggering Wheat Fungus

The USDA's Agricultural Research Service (ARS) has used molecular techniques to study how "the subversion of a single gene in wheat by two fungal foes triggers a kind of cellular suicide in the grain crop's leaves."

The USDA team has developed DNA molecular markers that can be used to rapidly screen commercial cultivars for the gene, Tsn1, that cause this condition.  Knowing the genetic marker allows for selective breeding that eliminates this condition.
