Last PhD for this year!
Great job done by @emma--c.bsky.social. Bravo Emma!
Also very proud of co-supervising this thesis with @ccilelorrain.bsky.social

So proud of you, @emma--c.bsky.social — congratulations on a brilliant PhD defense! 👩‍🎓🍾 It's been a pleasure to mentor your journey!

And huge thanks to the fantastic committee for the inspiring discussion!

Packed room for Emma Corre's PhD defense on transposable elements in rust fungi genomes.
Congratulations Dr @emma--c.bsky.social 👏👏👏

And what a lovely tribute to Barbara McClintock who discovered transposable elements in 🌽!!!

🌾A good day for cereal rust community!

Thrilled to share our 5 yrs of work with revolutionary discoveries on wheat & barley stripe rust fungi + we present the most comprehensive genomic resource (54 haploid genomes) ever developed for any wheat rust fungi.

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.

#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 of hedge bindweed (#Calystegia sepium) caused by #Puccinia convolvuli, here with uredinia & telia, found, along the Ru de Gally (Villepreux, FR).

#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 various-leaved fescue (#Festuca heterophylla), caused by #Uromyces festucae or #Puccinia festucae (?) 🤔(Les Clayes-sous-Bois, FR).
