Pyrenophora tritici-repentis is a plant pathogen of fungal origin, causing a disease called tan spot or helminthosporiosis, that affects mainly wheat in its more common varieties. It forms characteristic, dark, oval-shaped spots of necrotic tissue surrounded by a yellow ring[1]. It is responsible for losses that account for up to 30% of the crop[2], due to its effects reducing photosynthesis. Parthenogenesis and toxicity in P. tritici-repentis is controlled by a single gene, transformations of this gene cause the pathogen to become benign when interacting with wheat [3]. This has major implications for those in agriculture seeking to combat the effects of this fungus.
