Transposable elements are one of the major contributors to genome-size differences in metazoans. Despite this, relatively little is known about the evolutionary patterns of element expansions and the element families involved. Here we report a broad genomic sampling within the genus Hydra, a freshwater cnidarian at the focal point of diverse research in regeneration, symbiosis, biogeography, and aging. We find that the genome of Hydra is the result of an expansion event involving long interspersed nuclear elements and in particular a single family of the chicken repeat 1 (CR1) class. This expansion is unique to a subgroup of the genus Hydra, the brown hydras, and is absent in the green hydra, which has a repeat landscape similar to that of other cnidarians. These features of the genome make Hydra attractive for studies of transposon-driven genome expansions and speciation.

Dit is een vraagje voor @RSMuseum wiens huidige werkgebied ligt in de comparative life sciences.https://t.co/mNruxq9fJg

Is die klap autist weer mijn info aan het jatten, @RSMuseum En zitten geen hydra's in vaccins!!!

Tip. Dit boek https://t.co/JrXKBOYZlo is nog steeds onderdeel van m'n https://t.co/sqcVlU6eI6 Maar zijn artikelen @edyong209 in The Atlantic over Covid heb ik verslonden. Ik ben heel dankbaar dat ik niet alleen op NL wetjo's was aangewezen afgelopen anderhalf jaar.
