This week we're running the Transposable Elements course with @valentinapeona.bsky.social and @ritarebollo.bsky.social

www.physalia-courses.org/courses-work...

#TE25 #Bioinformatics #Genomics

Thank you so much Samuel! 🤩

This has been a fantastic course, very well done @valentinapeona.bsky.social and @ritarebollo.bsky.social ! 🙌
Looking forward to continue diving into the field 😊

3/9 The black-or-white throat polymorphism is explained by the interaction of a transposable element (an LTR retrotransposon) upstream ASIP with ASIP coding variation. Mantle and neck side coloration is encoded by additive effects of regulatory variants upstream ASIP.

A mosaic of modular variation at a single gene underpins convergent plumage coloration The reshuffling of genomic variation from multiple origins is an important contributor to phenotypic diversification, yet insights into the evolutionary trajectories of this combinatorial process and ...

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005
How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

🚀 The next edition of Bioinformatics of Transposable Elements with @valentinapeona.bsky.social & @ritarebollo.bsky.social is just around the corner!

Gene traffic mediated by transposable elements shaped the dynamic evolution of ancient sex chromosomes of varanid lizard Lizards usually exhibit frequent turnovers and a much greater diversity of sex determination mechanisms compared to birds and mammals, with the conser…

new work from the lab. Degeneration of Y chromosome does not seem to be one-way street. As a refugium of transposons @Alex Suh @valentinapeona.bsky.social , Y chromosome can recruit some genes by accidental TE burst: www.sciencedirect.com/science/article/pii/S1673852725002243

So happy to see our work published in MBE after a helpful and constructive journey with Editors and Reviewers!! #wildpopulation #nonmodels #E-Ranticorrelation #evolutionaryresearch #Aptenodytes #largepenguins

I am also deeply nostalgic as it was the last project with my friend and colleague, Daniele Di Marino, who sadly passed away last year. Missing a lot his energy in scientific research!

A severe cellular dysfunction threatens the already endangered Apennine brown bear The survival of Apennine brown bears, a small group of a few dozen animals isolated in the heart of the Apennines in Central Italy, not far from Rome, is at stake: cutting-edge techniques in molecular...

Awesome paper where conservation biology goes wild into genomics, experimental cell biology and biophysics!! Amazing job @emitruc.bsky.social and team 🐻
