A quick tutorial blog on a method I haven't seen before to plot gene gain/loss from e.g. CAFE5 across a phylogeny - and clearly shows I always have fungi on the mind 🤓🍄

@tobybarilbio.bsky.social and I are very excited to release MycoMobilome! A very extensive effort to discover, QC and annotate TEs across the fungal kingdom.

👉 Ready-to-use for your own genome with a simple tutorial!
👉 Metadata about TEs discovered in your genome!
👉 Contribute and get recognition!
1/ Ever needed to annotate TEs in a fungal genome, but didn't know where to start?

We have released #MycoMobilome, a community-focused non-redundant database of transposable element consensus sequences for the fungal kingdom, constructed from >4,000 fungal genomes!

Super excited to see our bioRxiv paper out! It furthers our understanding of an FHB resistance locus in timopheevii with some DON resistance too!

🍄 Today marks #UKFungusDay where we get to celebrate the weird and wonderful kingdom of Fungi.

As well as being fundamental to a healthy ecosystem, and often fascinating to spot, #Fungi can be devastating to plant and animal populations.
