Glad to share our latest article “Off-season sex in #Zymoseptoria tritici: little room for late encounters”, which continues our series of studies conducted in #ADEPTeam @inrae-bioger.bsky.social on the epidemiological determinants & impact of sexual reproduction in STB. doi.org/10.1016/j.fg...

📣 Three new Master’s 2 (M2) internship opportunities in phytopathology are offered for 2026 within the #ADEPteam @inrae-bioger.bsky.social @inrae-dpt-spe.bsky.social, focusing on the study of plant-pathogen interactions: eng-bioger.versailles-saclay.hub.inrae.fr/teams-and-pl...

Après la journée des scolaires, les collègues @inrae-bioger.bsky.social se mobilisent ce week-end pour faire découvrir les #champignons - bons, brutes & truands ! - sous toutes leurs facettes au grand public pour la #FêteDeLaScience à l’ENS Paris-Saclay @univparissaclay.bsky.social. Venez nombreux !

Les champignons, les bons🍄‍🟫🍺🥖, les brutes 🍄🍄‍🟫 et les truands 🍄‍🟫☘️c’est ce week-end ! @inrae-bioger.bsky.social @spsplantsciences.bsky.social #Phytopathologie mais aussi #InteractionsMicrobiennes #MetabolitesSpecialisés #ANR-FRiPPon

Collecte de champignons - bons, brutes ou truands !? - à présenter en fin de semaine à l'occasion de la #FêteDeLaScience 🔽

"Off-season sex in #Zymoseptoria tritici: little room for late encounters" @biorxivpreprint, sharing our latest study on sexual reproduction in Z. tritici — its epidemiological determinants & impact — may interest those working on plant pathogen dynamics. doi.org/10.1101/2025...

(1/5) Happy to share our latest paper "#Uromyces plumbarius first reported on Oenothera lindheimeri in Europe with widespread distribution and association with two common natural enemies of rust fungi". Thanks @pascal-frey.bsky.social, K Meyer & @erikslootweg.bsky.social! doi.org/10.1007/s106...

Congratulations to Axelle Deroubaix who brilliantly presented her work at #ISMPMI2025! #ProudSupervisor #ShySM-ANR-project shysm-project.hub.inrae.fr @eccp-lab.bsky.social, @inrae-bioger.bsky.social, @inrae-dpt-spe.bsky.social

Shapes and hues — orange, brown, black on green — vivid or blending, silken, bristly, sharp, often powdery... Let us wager that the phenotypic & genotypic diversity of #Puccinia graminis on wild (mostly) and cultivated #grasses (less ) is locally as rich as symptoms 🤩.

Glad to share our review article: "Potential of #ServicePlants for regulating multiple pests while limiting disservices in agroecosystems", a project dating back to the Covid-19 lockdown/de-lockdown era that gave a special flavor to the writing retreats doi.org/10.1007/s135...

📢 A diffuser svp ! Appel à prélèvement de #rouille noire @inrae-bioger.bsky.social #ARVALIS. Aidez-nous à caractériser la situation épidémiologique 2025 : ouvrez l'œil dans vos #blés et transmettez des échantillons ! 🙏

This week we had the pleasure to host @inrae-bioger.bsky.social our #GEVES-Gip partners for a hands-on training day to assess #wheat resistance (susceptibility 😏) to stem #rust. Kudos to Kévin Meyer for leading the session as part of the RouilleNoire_2.0 #FSOV #SEMAE project!

L’affaire des souches chinoises de #Fusarium graminearum interceptées aux États-Unis (suite), avec des éléments d’analyse mis en forme par @yannkerveno.bsky.social à retrouver dans le fil @revuesesame.bsky.social de la semaine 🔽

My interview on BBC World Service as a podcast ▶️ www.bbc.co.uk/programmes/w... Thanks @peaseroland.bsky.social for the opportunity 🤗!

L’affaire des souches chinoises de #Fusarium graminearum interceptées aux États-Unis : mon analyse à chaud ▶️ zenodo.org/records/1560...

Sachant qu'il suffit de se baisser dans un champ pour trouver du F. graminearum, cette accusation est-elle vraiment sérieuse ? L’instrumentalisation de la phytopathologie et de la réglementation phytosanitaire à des fins géopolitiques se poursuit… ▶️ theconversation.com/la-russie-et...

We had the pleasure of welcoming James Brown from John Innes Centre for two days of engaging discussions with the #ADEP team and @inrae-bioger.bsky.social on the durability of resistance to fungal diseases in wheat.

#SFP2025 Anne Genissel from @inrae-bioger.bsky.social on the evolution of plasticity of Zymoseptoria tritici

Pleased to share this review @cp-oneearth.bsky.social‬, based on the extensive "RegulNat" collective expertise @inrae-france.bsky.social url.inrae.fr/3Tz2eWj! "Protecting crops with plant diversity: agroecological promises, socioeconomic lock-in, and political levers". doi.org/10.1016/j.on...

Ravi de partager en ce #PlantHealthDay ma "contribution photographique à l’inventaire des Pucciniales autour des Clayes-sous-Bois", avec + de 100 espèces de #rouilles 📷 présentées dans le Bulletin des Naturalistes des #Yvelines www.siteany78.org/ ▶️ zenodo.org/records/1524...

The recovery of #Puccinia graminis from aecia on #Berberis sampled last week just started, with leaves placed above a mix of wild grasses and cultivated cereals, as in 2024. Goal for the Alicia Culot's PhD thesis @inrae-bioger.bsky.social: to gather info on the primary hosts & formae speciales.

Merci beaucoup Frédéric @wheatpath.bsky.social pour cette "Sortie Rouilles" instructive & bucolique 🤩 @inrae-bioger.bsky.social #RustFungi

Millésime 2025 de la désormais classique sortie "Vad'rouilles #ANY" aux Clayes-sous-Bois, en compagnie de collègues de @inrae-bioger.bsky.social : découverte d’une vingtaine d’espèces de #rouilles, dont #Uromyces ficariae, Uromyces poae s.l., #Puccinia albescens, et #Tranzschelia fusca.

Happy to share this preprint confirming "Uromyces plumbarius first reported on Oenothera lindheimeri in Europe with widespread distribution and association with the rust hyperparasite Sphaerellopsis sp." Thanks @pascal-frey.bsky.social & @erikslootweg.bsky.social! doi.org/10.1101/2025...

Glad to share this article, based on the very first data 🤠 I collected in plant disease epidemiology at the start of my career in 1999: "Disruptive effect of #rainfalls on the diurnal periodicity of airborne #wheat #rust spores under field conditions." www.sciencedirect.com/science/arti...

Félicitations Thierry pour ton HDR ! 👏

First #Zymoseptoria tritici inoculation with 🌞 for the 2nd year of our #wheat varietal mixture trial @arvalis.bsky.social @inrae-bioger.bsky.social at Versailles #COMBINE #MOBIDIV.

Very smart demonstration of fungal effectors facilitating cell-to-cell mobility in plants by @ifudal.bsky.social #ECFG17 @inrae-bioger.bsky.social

First beautiful pustules of #Puccinia graminis f. sp. tritici obtained by K. Meyer under optimized controlled conditions @inrae-bioger.bsky.social L2 lab. The evaluation of the #wheat varietal panel will soon begin as part of the #FSOV @semae_officiel RouilleNoire_2.0 project.
