That's no moon, it's a Starship: Giant transposons driving fungal horizontal gene transfer

AH Bucknell, MC McDonald - Molecular Microbiology, 2023 - Wiley Online Library
To date, most reports of horizontal gene transfer (HGT) in fungi rely on genome sequence
data and are therefore an indirect measure of HGT after the event has occurred. However, a …
