Wonderful (and humble) essay on mentorship by Brandon Gaut, on occasion of Brandon receiving the inaugural Mentorship Award of @genetics-gsa.bsky.social. I hope this will be widely read! academic.oup.com/genetics/art...

Happy to share our new work with exciting findings, incl. different centromere organisations and all kinds of weird polyploids giving rise to the mysterious carnivorous sundews! Great word led by my postdoc Laura in collaboration with @plantgenomes.bsky.social www.biorxiv.org/content/10.1...

Our new preprint on somatic TE transposition in A. thaliana is out! It looks like TEs jump like crazy! Led by the amazing @heenaa02.bsky.social and with Hans-Wilhelm Nuetzmann from Exeter www.biorxiv.org/content/10.1...

6/ 🙏 Huge thanks to the amazing collaborators and co-authors who made this work possible! 🧑‍🔬 Basile Leduque, Leandro Quadrana, Keith Slotkin, Alexandros Bousios (@abousios.bsky.social) & Hans-wilhelm Nuetzmann

5/ 💻 Surprise package! We developed a custom pipeline, deNOVOEnrich, to profile somatic TE insertions from TEd-seq short-read data. Using split-read mapping, we pinpoint new somatic insertions at base-pair resolution 🧬🔍 Check it out: github.com/hAmbreen02/d...

4/ 🔥 Somatic insertion hotspots of the EVADE transposon are enriched at environmentally responsive genes 🌄 - including Resistance gene and biosynthetic gene clusters. Is stress guiding TE activity, or are TEs tuning stress responses? Somatic genome plasticity 🧬

3/ 🧬 Our work shows somatic TE activity in Arabidopsis is non‑random and family‑specific. Different TE families prefer distinct genomic niches - is it driven by underlying epigenetic code, or are they avoiding conflict in a shared genome ecosystem? 🤔

2/ Combining distinct experimental conditions, we traced a roadmap of expected TE movement in somatic cells 🌿, capturing ~200K new TE insertions across multiple families in the process.

1/📢News from TE diary - Somatic transposition in Arabidopsis is more explosive than we imagined! Thrilled to share our latest findings - TEs make new somatic insertions en masse, reshaping the somatic genome🧬with surprising frequency🍃 @abousios Hans-Wilhelm Nuetzmann www.biorxiv.org/content/10.1...

1/2 Somatic TE transposition in plants is getting traction again (70 years after McClintock's discovery of "controlling elements")! A very large collection of somatic TE insertions in A. thaliana described by Ambreen et al.(www.biorxiv.org/content/10.1...).

2/2 See also @movillome.bsky.social's paper from my lab on using PacBio long-read sequencing to discover somatic TE insertions with high sensitivity and specificity in an unbiased manner -- an excellent complement to powerful short-read based enrichment methods (www.biorxiv.org/content/10.1...)

1/7 I am very excited to announce our🌹NEW PAPER OUT IN 𝑁𝐴𝑇𝑈𝑅𝐸!🌹 𝐃𝐑𝐈𝐕𝐄 𝐓𝐎 𝐒𝐔𝐑𝐕𝐈𝐕𝐄: Bimodal centromeres in pentaploid dogroses shed light on their unique meiosis With the Ritz and Kovařík labs we show a potential role for centromeres on 𝘙𝘰𝘴𝘢 𝘤𝘢𝘯𝘪𝘯𝘢 bizarre reproduction! www.nature.com/articles/s41...

NIH funding supporting the HMMER and Infernal software projects has been terminated. NIH states that our work, as well as all other federally funded research at Harvard, is of no benefit to the US.

💥🥳 At long last, our latest paper is out! Gag proteins of endogenous retroviruses are required for zebrafish development www.pnas.org/doi/10.1073/... Led heroically by Sylvia Chang & @jonowells.bsky.social A study which has changed the way I think of #transposons! No less! 🧵 1/n

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇

Postdoc jobs in the Gaut lab! Brandon isn't on here, so I can be frank: he is fantastic. I did my postdoc with him and he is not only an amazing scientist but one of my favorite humans. I would have happily stayed in his lab forever if that was feasible. recruit.ap.uci.edu/JPF08999 #plantscijobs
