Fungi's genetic sabotage in wheat discovered:
Using molecular techniques, ARS researchers and their collaborators have shown 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-and they've also developed DNA molecular markers that can be used to rapidly screen commercial cultivars for the gene, called Tsn1, so it can be eliminated by selective breeding.
