A huge amount of work went into this paper by myself and all the co-authors, and thanks to CABI, @imperiallifesci.bsky.social and @ox.ac.uk for the press releases:

And fungal geneticists favourite buzzword: an 80kb Starship mobile element has inserted between highly expressed genes in the Fusarium xylarioides population which infects the people's favourite arabica coffee ☕

Horizontally transferred regions contain highly-expressed genes following infection of coffee plants, including 'secreted in xylem' effector genes from Fusarium oxysporum. Specific transposons are also shared between Fusarium xylarioides and F. oxysporum.

We found five large horizontal transfers which are differentially present across the populations. Several of these show close matches to mobile pathogenic chromosomes from Fusarium oxysporum.

Now to dive into the details...

We published the first nearly-chromosomal reference genome for Fusarium xylarioides, the coffee wilt pathogen, and found multiple genetically differentiated populations within a species complex

If you don't want the directors cut, an excellent primer also published in @plosbiology.org explains in common language our key findings, and why they matter: journals.plos.org/plosbiology/...

[as you can probably tell] it is a very new account!
