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

Contrasting centromere structures in carnivorous sundews uncover a dynamic evolutionary trajectory shaped by polyploidy and chromosomal remodeling
Sundews (Drosera) are carnivorous plants that capture prey using mucilage-producing glands with both secretory and absorptive functions. Within a remarkably diverse clade that includes the Venus flytr...

Somatic mobility of transposons is explosive and shaped by distinct integration biases in Arabidopsis thaliana
Background The movement of transposable elements (TEs) in somatic cells generates genetic and phenotypic diversity across the soma of individual organisms. This process is especially important in plan...

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 🧬🔍

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?

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/ 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.
