What a systems view can tell us about genomic imprinting in plants! Happy collab with @vojta-ce.bsky.social @omeriltas.bsky.social @apecinka.bsky.social @susnatas.bsky.social @kovacik.bsky.social A. Přibylová and led by Trezalka Budinsky www.biorxiv.org/content/10.6...

Imprinted regulatory networks reveal the molecular cross-talk between paternal and maternal genomes in the endosperm of Arabidopsis arenosa

Imprinted genes do not act alone to shape seed development, but as a complex network - just like any other gene. Yet, the molecular context in which they are embedded, i.e. their gene network, remains...

My talk from the #NextflowSummit is on YouTube! youtu.be/LbA_d4oOpDQ I talked about my recent odyssey with AI-written software, including #RustQC, rewrites.bio, Trim Galore and a FastQC rust rewrite 👀 This was honestly one of my favourite talks to date. I hope it's interesting for folks 😊

We are thrilled to share our latest work uncovering a completely novel pathway in plants, where Pol II elongation factor SPT6L recruits AGO4 to guide mRNA methylation 🌿🔬 www.biorxiv.org/content/10.6... #PlantSci #Epigenetics #RNA #Preprint #epitranscriptomics

Our new preprint on how in plants ARGONAUT 4 controls RNA cytosine methylation (yes RNA!) which then prevents premature transcription termination #PlantScience #Epitranscriptome #siRNAs

Hello BlueSky! Super excited that this work is out thanks to a great team work with Nélida Padilla-Garcia as lead author! We looked at what shaped the purging and fixation of TEs in populations across Arabidopsis lyrata species range. Short answer: the usual suspects, but also genomic imprinting!

Padilla-García, @plantreproevo.bsky.social et al. compared transposable elements in Arabidopsis lyrata, finding that demographic events and positive selection on epigenetically silenced TEs contributed to the spread of genomic imprinting. 🔗 doi.org/10.1093/molb... #evobio #epigenetics
