I'm frequently asked if we can use XRM imaging to study Arabidopsis, and the answer is absolutely yes. The pollen grains were segmented using basic grayscale thresholding. This scan used the 4X lens, stayed tuned for results from the 20X. @danforthcenter.bsky.social @zeiss-microscopy.bsky.social

#OurFridaySeminar: @ammarabdalrahem.bsky.social presents his new results on #functional and #evolutionary comparison of #sexual and asexual lineages of #poplar #rust

Yesterday I gave my post-sabbatical seminar at #INECOL. A great opportunity to remember good times at @umr-iam.bsky.social !

#Rust on reed canary grass (#Phalaris arundinacea) likely caused by #Puccinia sessilis, hyperparasitized by Sphaerellopsis sp., along the Ru de Gally (Villepreux, FR).

#Rust on leaves of tall fescue (Schedonorus arundinaceus syn. Lolium arundinaceum) caused by #Puccinia graminis, heavily hyperparasitized by Sphaerellopsis sp., along the Ru de Gally (Villepreux, FR).

#Rust of lady's thumb (#Persicaria maculosa) caused by #Puccinia polygoni-amphibii — here hyperparasitized by Sphaerellopsis sp. — found along the Ru de Gally (Villepreux, FR).

#Rust on maize (#Zea mays) caused by #Puccinia sorghi with abundant urediniospores (28-32 × 20-26 µm) and a few rare teliospores — here hyperparasitized by Sphaerellopsis sp. ; sampling by Laura Nunes 🙏 from @ideevl.bsky.social field experiments (Gif-sur-Yvette, FR).

Some uncommon rusts in Fermanagh yesterday Uromyces trifolii-repentis on Trifolium repens, and Chrysomyxa empetri on Empetrum nigrum. This is the first Irish record of the former. #FungiFriends

🎉 Our study on the diversity of avocado fungal e #endophytes in orchards under contrasting management is now out! 🍄🌳🥑 Next step: assessing their antifungal and entomopathogenic activity 💀🪲

#Rust of small burnet (#Sanguisorba minor) caused by #Phragmidium sanguisorbae (Moudeyres, FR).

Local cluster of stem #rust on grasses caused by #Puccinia graminis, not observed elsewhere, but here explained by the presence of a #Berberis thunbergii hedge, with old aecia as evidence: new example of interaction between wild and anthropized compartments (near Moudeyres, FR).

#Rust on little green sedge (#Carex viridula syn. C. oederi, also identified as C. flava agg.) likely caused by #Puccinia schroeteriana, with urediniospores 18–22 × 16–20 µm, here hyperparasitized by Sphaerellopsis sp. (Lac bleu, near Moudeyres, FR).

#Rust of bladder campion (#Silene vulgaris) likely caused by #Uromyces behenis (Moudeyres, FR).

#Rust on false oat-grass (#Arrhenatherum elatius) caused by #Puccinia coronata (Millau, FR).

Stem #rust on false oat-grass (#Arrhenatherum elatius) caused by #Puccinia graminis (Millau, FR).

I love the idea of "micropublications" www.micropublication.org (preparing one now)

Je serai le 26/07 dans la vallée du Valromey, au sein du Bugey, pour le Festival des Arbres. Je vous y raconterai l'incroyable polyphonie jouée par les arbres et les champignons dans nos forêts ...

Independent researcher @ccilelorrain.bsky.social presented how she used GWAS in the field to identify multiple novel effectors of Zymoseptoria tritici, which could be validated experimentally!

Recently I learnt that EMBL-EBI has a free online course about AlphaFold — how it works, strengths and limitations, how to use it — and it's very good! There are also little quizzes and interactives. www.ebi.ac.uk/training/onl...

The range of the key oversummering regions of #Puccinia striiformis f. sp. tritici in northwestern #China has expanded westward doi.org/10.1094/PHYT...

#2025ISMPMI Stella Cesari gives a beautiful presentation on her research on MAX effectors. Avr-Pia binds to HMA domain of rice HPP09. Screens reveal many interactions with rice proteins. Highlight: Avr-Pib interacts with MAPKKK.

Two months after the survey on #Berberis vulgaris, a return to Burgundy near #Dijon with Alicia and Ulysse to search for stem #rust on wild #grasses and possibly on cultivated cereals growing along the edges.

« C’est difficile de repérer le virus » : une maladie liée aux tiques… transmise par le fromage. Reportage du @leparisien.fr au laboratoire Tous Chercheurs de #INRAE_Nancy : www.leparisien.fr/environnemen...

Bring your #PlantScience publishing questions for our Editors! Catch Holly on our stand at #2025ISMPMI with @hacquardst.bsky.social, Ralph Panstruga, Ari Sadanandom, @pietrospanu.bsky.social and Ertao Wang! 📅 TODAY ⏰ 13:00–14:00 🗺 New Phytologist Foundation stand, poster hall

Stéphane Hacquard proposes manipulating fungal community-plant homeostasis & using bacteria-mediated resistance to control pathogens. He ties analyses to more functional outcomes, identifying molecules that manipulate carbon catabolism and/or alter the microbiome to promote health. #2025ISMPMI

Viral genomes might encode more proteins than we initially thought! Intrigued? Come see my poster on the identification of potentially new ORFs in the potato virus X genome. Tuesday 9:55-11:30, P-266 @geminiteamlab.bsky.social #2025ISMPMI

#RP_INRAE Dans ce nouveau Décryptage, un aperçu des travaux d’INRAE pour préparer les forêts de demain, à l’échelle de l’arbre jusqu’au suivi des grands biomes forestiers, de la production de connaissances au développement d’outils à destination des gestionnaires forestiers. 👉 url.inrae.fr/3U506HW

Kickoff meeting of the EpiMyc Project (The epigenetics of mycorrhiza) funded by @agencerecherche.bsky.social‬, with nice talks of @stephane-maury.bsky.social, @ifudal.bsky.social and Claire Veneault-Fourrey @umr-iam.bsky.social on epigenetics of plants and associated fungi.

We asked the contributors to our special issue on #fungi to tell us what their favorite fungi are.... www.cell.com/current-biol...

Check out our fungi-tastic special issue, full of marvels of mycology — and many articles accessible for free! 🍄🍄🍄 www.cell.com/current-biol...

#Rust of sea thrift (#Armeria maritima) caused by #Uromyces armeriae (Saint-Briac sur Mer, FR).

#Rust on sea campion (#Silene uniflora, syn. Silene vulgaris subsp. maritima) caused by #Uromyces behenis, inducing characteristic purple spots. Aecia and telia are visible here on the leaves and stems, but this species does not produce urediniospores (Saint-Briac sur Mer, FR).

The scope of #fungi #biodiversity is only beginning to be fathomed. Every day almost ten new species are described. 🍄🤯 David Hibbett László Nagy and Henrik Nilsson introduce the fungal tree of life. www.cell.com/current-biol...

#OurFridaySeminar: @sebbyrust.bsky.social makes an update on #Rust #fungi #genomics

Our new paper is out! We observed a loss of function in mating compatibility for HD genes for the first time in basidiomycete fungi, and new evolutionary strata in the absence of sexually antagonistic selection! @tatianagiraud.bsky.social More details here 👉 www.nature.com/articles/s41...

Be clear: this alternative technique doesn’t work. Note to self: In the future paper showcasing our brilliant results 😎, don’t forget to mention this failed attempt. A small ego wound, but one that will save colleagues from trying in vain for the 249th time 🤡. #NegativeResult

And now, good vibes
