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...

The fruit of a team gathering complementary and unique skills of different people, I love when this happens! And happy about the result :) congrats @omeriltas.bsky.social , @kovacik.bsky.social , L. Salomon, S. Hafidh, M. Certner, P. Talacko & K. Harant! nph.onlinelibrary.wiley.com/doi/10.1111/...

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self-fertilization, often resulting in the ‘selfing syndrome’ (e.....

It's great to see this work finally out! @newphyt.bsky.social Here we showed that auxin production after fertilization is a conserved, paternal-triggered mechanism for seed initiation in angiosperms.

Big congratulations Mohammad, you nailed it! 👏🏻

Do you want to do a Masters in Evolutionary Biology? The call for applying to the MEME program is now open! MEME is a fantastic 2-year MSc between four European Universities on all areas of Evolutionary Biology. Apply and study in Sweden/France/the Netherlands/Germany/USA/Switzerland! www.evobio.eu

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Our last work is out! led by @mjavad1991.bsky.social as first author and another smooth collaboration with @rosischmickl.bsky.social! We explore the evolution of male (pollen) and female (ovule) investment in Brassicaceae, if you're curious on the answers, it's 👇 academic.oup.com/aob/advance-...

Interested in the evolution of molecular interactions ? We are recruiting a new PhD student with a background in proteomics to study the diversification of the receptor-ligand interaction controlling plant self-incompatibility. --> details here : initiative-excellence.univ-lille.fr/fileadmin/us...

Did you know plants can change sex expression within a single generation, and reversibly at that?🌱 What else but #epigenetics might play a role in this? 🧬 Read more in the new study published at @camphilsoc.bsky.social's Biological Reviews ⬇️ 🔗 buff.ly/oL0JETy (TŽ)

Just wrapped up an amazing time at #EMPSEB30. A truly unique event by PhD students, for PhD students packed with insightful talks and outstanding networking with future colleagues. If you’re a PhD student in evo-bio, this is the meeting you don’t want to miss! #EMPSEB30 #EvolutionaryBiology

If bottom-up approaches still needed evidence they work, #EMPSEB30 gave it. A warm atmosphere, sustainability prize, engaging DEI session, emotional workshops, alternative presentations, so many out-of-the-box things. Altogether with a really high scientific quality. Thank you @empseb30.bsky.social!

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!

Molecular Biology and Evolution@molbioevol.bsky.social · last yr.

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
