Plz repost. Fresh Preprint led by Alex Guyon When a pathogen pushes into a cell already occupied by a symbiotic fungus, things change. New membrane phosphoinositides at haustoria may impact immunity & trafficking - And the roots are more resistant! biorxiv.org/content/10.110…

Congratulations Nick Dunken, exceptional PhD defense..

Amino acid competition shapes A. baumannii carriage. A. baumannii uses ornithine to compete w/ microbiota & persist in gut. Amino acid supplementation & differences in diet promote A. baumannii gut colonization in mice and humans Lauren Palmer 👩🏻‍🔬 cell.com/cell-host-micr…

⚠️Excited to share my latest in The Plant Cell🌱! We show that chloroplasts form membrane contact sites (MCS) with the pathogen interface to drive focal immunity, mediated by a tethering complex🔗! Full story 👉 doi.org/10.1093/plcell… #PlantScience #PlantImmunity

Alternative splicing of OsNPR3 promoted by the bacterial TAL effectors-targeted splicing regulator OsRBP11 antagonizes OsNPR1 function and enhances disease susceptibility in rice - Mol. Plant sco.lt/7GLfzk

I am excited to share my research is now published! 📚 An apoplastic fungal effector disrupts N-glycosylation of ZmLecRK1, inducing its degradation to suppress disease resistance in maize nature.com/articles/s4147… @SN and #SNAuthor.

#iMMM2025 Alexandra Dallaire with a banger of a research finding - AM fungi have lost the tools (ie polymerases) for DNA replication and translesion repair resembling findings in Microsporidia So, how does replication work? biorxiv.org/content/10.110…

#iMMM2025 we are starting the second day with Lisa Mahdi from Alga Zuccaro who dissects the interactions of Serendipita fungi with barley and other barley pathogens such as Bipolaris sorokiniana, the role of synthetic bacterial microbiota

#iMMM2025 Alan Wanke (@alanwanke.bsky.social) shows that the Mucoromycotina fine root endophyte Lyc-1 (from a lycophyte) colonises carrot root organ cultures where transcriptional responses differ from those of the AM fungus R. irregularis

Research Briefing in Nature Plants "Glycosylation disruption is a new virulence strategy for a plant fungal pathogen" doi.org/10.1038/s41477…: highlight of our recent findings published in Nature Plants doi.org/10.1038/s41477….

I am happy to see this out! Plant-microbe relationship (mutualistic, commensalistic, parasitic) is not fixed, but rather dynamic, depending on the specific context. We summarize the current knowledge on this. Hope you enjoy~ jstage.jst.go.jp/article/plantb…
