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!

AlphaFold - A practical guide AlphaFold - A practical guide

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.

#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.

A person giving a scientific talk on a purple lit stage with a lectern that has an MPMI logo. The power point slide shows network analysis between fungi and bacteria in the plant microbiome

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.

Viral genomes might encode more proteins than we initially thought!

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.

MyShroom Several contributors to our Fungi special issue reflect on their favorite taxon, telling us why it is special to them and how it has shaped their science.

We asked the contributors to our special issue on #fungi to tell us what their favorite fungi are.... 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. 🍄🤯

Repeated loss of function at HD mating-type genes and of recombination in anther-smut fungi - Nature Communications Basidiomycete fungi typically have two mating-type loci located on different chromosomes. Here, Lucotte et al. report the convergent loss-of-function of mating-type genes across several species of phy...

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!

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 🤡.

#Rust of erect brome (#Bromus erectus) caused by #Puccinia coronata, here with a mix of urediniospores & teleutospores (La Roche-Guyon, FR).

One year later, same site — the #rust on common ball flower (#Globularia bisnagarica) caused by #Puccinia globulariae is still present. It appears to persist on dry leaf residues. And this time, grayish telia are visible, with basidia beginning to germinate (La Roche-Guyon, FR).

Grass choke disease on #Dactylis glomerata caused by #Epichloë typhina (Ascomycota), seen here with mostly immature stromae and mycophagous larvae of #Botanophila sp. involved in cross-fertilizing the fungus (La Roche-Guyon, FR).

And the gem of the day 🤩: #rust on sickle hare’s ear (#Bupleurum falcatum) caused by #Puccinia bupleuri, showing the full range of stages — aecidiospores, urediniospores & teliospores — and, as a bonus, itself hyperparasitized by #Tuberculina persicina (La Roche-Guyon, FR).
