Promoter recruitment drives the emergence of proto-genes in a long-term evolution experiment with Escherichia coli
De novo gene birth from non-genic sequence has received considerable attention due to the widespread occurrence of genes that are unique to particular species. This study shows that within the short evolutionary timescale of the iconic E.plos.io
My latest preprint exploring transposable element (TE) activity in the genomes of sparrows.

We found remarkably high levels of repeat content in the newly generated genomes of
Bell's, Song, and Savannah Sparrow. 31% of the Bell's sparrow genome is spanned by repetitive elements.
This is ~3x as much as previously reported in most songbirds.
Thanks to all my co-authors for their contributions to this project!

Remarkably high repeat content in the genomes of sparrows: the importance of genome assembly completeness for transposable element discovery.
Transposable elements (TE) play critical roles in shaping genome evolution. However, the highly repetitive sequence content of TEs is a major source of assembly gaps.bioRxiv
