The bZIP transcription factor PnAda1 functions as a regulator of virulence, fungicide tolerance and necrotrophy in the wheat pathogen Parastagonospora nodorum https://www.biorxiv.org/content/10.64898/2026.08.18.745654v1

💥 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. 👇

🧬 New CCDM research reveals how the wheat pathogen Parastagonospora nodorum switches on genes needed to infect crops, uncovering potential targets for future disease control. 🌾 Read more: apsjournals.apsnet.org/doi/10.1094/... #GRDC, @curtinuniversity.bsky.social

Our @theccdm.bsky.social postdoc @callumverdonk.bsky.social came up with the goods @cbsmwa.bsky.social!!! Congrats on the New Investigator Award! 🏆💪 #CBSMWA #CBSMWA2025

Big thank you to @cbsmwa.bsky.social for letting me waffle on about my work on Pf2 and it's role in effector regulation! #effectors #CBSMWA #CBSM @theccdm.bsky.social @karchuntan.bsky.social

📢💥Team work pays off!!! Looks @theccdm.bsky.social lads found a new epistasis-regulated (probable) necrotrophic effector from Stago nodorum @callumverdonk.bsky.social @ShotaMorikawa69

🧠 Can AI help us understand how fungal pathogens infect plants? A new review says yes. AI tools show promise in modelling effector–plant protein interactions to fight crop disease🌾 📖 doi.org/10.1016/j.cs... #GRDC #CurtinUni @callumverdonk.bsky.social @kgagalova.bsky.social @mcderbyshire.bsky.social

Our @theccdm.bsky.social @callumverdonk.bsky.social talks about effector regulation in Parastagonospora nodorum in @inrae-france.bsky.social hosted by @ifudal.bsky.social

What an absolute pleasure to present our work to the EPLM group at INRAe in France. Fantastic research being done by fantastic people!
