Very glad to share our first venture/paper on the pathotyping of Australian Blumeria graminis f. sp tritici isolates. The study was led by our @theccdm.bsky.social and @InterGrain PhD student Ancy Tony 👩‍🔬 in collaboration with Ben Saunders of the Curtin Fish Ecology Lab.

💥 Out now! 💥 Our @MPMIjournal publication, led by @theccdm.bsky.social Shota Morikawa & @callumverdonk.bsky.social , looks at domain functions of a transcription factor involved in necrotrophic effector regulation and co-factor interactions in Parastagonospora nodorum, a fungal pathogen of wheat. 👇

Happy to have presented a talk at #IWC2026Bologna on @theccdm.bsky.social research, highlighting that wheat diseases may not follow a bipartite single pathogen-plant interaction. Glad that it stimulated some nice after-session discussions and potential collaborations.
