A H3K27me3 reader complex couples H3K27me3 accumulation to nascent transcription of transposable elements in Paramecium - Genome Biology Background The ability to deposit histone H3K27-trimethyl (me3) marks is essential for transcriptional repression by Polycomb Repressive Complex 2 (PRC2). This is largely attributed to Polycomb repres...

This week @annazaidmanremy.bsky.social and @jesuxueml.bsky.social were at the EMBL symposium entitled “The cellular mechanics of symbiosis: sensing friend from foe” @events.embl.org. They gave excellent presentations which sparked lively discussions! #EESSymbiosis #SymbioSky

Next, Jesus Uxue Mendez Leyva on a recently acquired bacterial endosymbionts in weevils. Their genomes have lots mobile genomic elements suggesting that they are undergoing a period of genomic instability, and the genes associated with TEs might play a role in the symbiosis
#EESSymbiosis

Following the #EESSymbiosis @events.embl.org through Bluesky! Keep posting! @annazaidmanremy.bsky.social gave a wonderful talk yesterday (I've been told!), & @jesuxueml.bsky.social will take the floor today! Have fun, I'm not jealous at all #FOMO And go Mobile Genetic Elements <3 #SymbioSky

We are looking for a Postdoc to join our lab at @oxfordbiochemistry.bsky.social. This is a dry-lab focused post on the computational analysis of long read single-cell sequencing data to understand the role of transposable elements (TEs) in early development. my.corehr.com/pls/uoxrecru... #TEsky

A reference-free pipeline for detecting shared transposable elements from pan-genomes to retrace their dynamics in a species - Genome Biology Background The role of transposable elements (TEs) in host adaptation has gained interest in recent years.

Hi! Florence Hommais, @nicolasparisot.bsky.social , and I are looking for a postdoctoral candidate to investigate the molecular dialogue between three weevil species and their endosymbiotic bacteria #symbiosis! Please see the #post-doc offer for more information. #SymbioSky #Bioinformatics

A cartoon/ digital drawing summarising the findings of the paper "Defensive fungal symbiosis on insect hindlegs" by T. Nishino et al published in 2025. On the top left, a female Megymenum gracilicorne bug shows off symbiotic organs on the hind legs where she carries Ascomycota fungi. These were previously assumed to be Tympanal organs in these bugs but only females had them?; that didnt make a whole lot of sense to the authors...To the right of the bug is a row of eggs lying side by side. The paper shows that the bugs deposit the symbiotic fungi on the egg surface after egg-laying. Next on the image, fungal conidia grow on the egg surface. The eggs are pinkish in colour. A few fungi wear sunglasses like they are body guards. The paper shows that they protect the eggs from Trissolcus brevinotaulus, a parasitoid wasp, that likes to lay its eggs inside the developing bug's eggs. There are two wasps in this cartoon "eyeing" the fungi and looking frustrated. Eggs turn from whitish to pinkish within 10-days because they are reflecting the body colour of the nymph within the eggs.

Had to draw a cartoon for this fascinating finding!
