Wrote a short piece on Transposable Elements as catalysts of evolutionary innovation for a forthcoming special issue of @naturerevgenet.bsky.social on, duh, Evolutionary Innovation!
www.nature.com/articles/s41...
In this Comment, Cedric Feschotte highlights evidence from diverse lineages showing that transposable elements are key drivers of evolutionary innovation, repeatedly introducing regulatory and coding ...

#TEsky Transposons drove the evolution of a male sex-determining gene from a female gene with deep introgression across cichlids doi.org/10.1126/scia...
A gene from the female pathway was repurposed to determine male sex in tilapia, revealing an unusual evolutionary mechanism.
🔥🔥🔥PREPRINT OUT🔥🔥🔥
microRNA annotation gets much easier!!!
MirMachine 2 is out!

We just published our new paper about an active Helitron transposon in wheat 🌾🧬
We found that it can be mobilised by heat stress when DNA methylation is reduced.
We document its full lifecycle: RNA -> circular DNA -> integration

Helitrons are a recently identified category of transposons. This study reveals that heat stress combined with reduced DNA methylation can mobilize a Helitron family in wheat. Its mobilization is gene...
Excited to share this new pre-print from the fantastic @kelsiehunnicutt.bsky.social! Kelsie put together a thoughtful and thorough review on hybridization in animal evolution: ecoevorxiv.org/repository/v.... She tracks notable shifts in perspectives on the study of hybridization through time.
In this study, the authors use the Caenorhabditis elegans model organism to show that maternal microRNAs are delivered from the intestine to embryos by the yolk, where they regulate gene expression an...
