When the fungus Ustilago maydis infects maize plants, tumour-like tissue growths develop. Researchers led by Prof. Armin Djamei have now discovered that the fungus hijacks a programme in the plant that is responsible for forming lateral roots: www.uni-bonn.de/en/news/002-... @effectomics.bsky.social

#2027ISMPMI - Try 2 for Jeju, Korea! Hope to see you there and I’m glad that South Korea gets to host after their turn was missed because of the pandemic. There is a promise of good food 🤤 Though I may need to start saving up now with the state of things… #2025ISMPMI

www.biorxiv.org/content/10.1... Up next at #2025ISMPMI @kseniakrasileva.bsky.social discussing work on protein language model for receptor engineering.

@kseniakrasileva.bsky.social is the first talk at the engineering traits session at #2025ISMPMI Branching into PRRs thanks to @danimstevens.bsky.social. The ?: Can we use language models to predict host and microbe proteins interaction outcomes? The answer: Yes! New “mamp-ml”does pretty well.

#2025ISMPMI - first new to nature chimeric NLR sensors being created, with integrated domains that do not have sequence or structure matches in the recorded life - raises questions on assessing biosafety & food safety aspects for these immune receptors for lab and field studies.

@angusb.bsky.social wants to engineer plant resistance proteins (NLRs) from scratch. Can we create protein domains to integrate into NLRs to catch pathogen effectors? New tech makes this possible now. Chose Magnaporthe and Fusarium effectors as targets - many steps later, it worked! #2025ISMPMI

Dani’s recent paper appears to be the top #2025ISMPMI post which is impressive for someone not here 💓 bsky.app/profile/dani...

In the trait engineer session and Aurelia Rakotondrafara makes a quip that her talk has no AI 😅 Under-revision-study from her lab uses a treatment of a mycovirus protein to reduce growth and increase fungicide susceptibility of the pathogen Sclerotinia sclerotiorum. #2025ISMPMI

#2025ISMPMI Aurelie Rakotondrafara shows very interesting effects of mycovirus infection of Sclerotinia on virulence on the host plant. Take home to use mycoviruses and plant viruses to limit the spread of fungal pathogens.
