Evolution of Tunicate lifestyles shaped by Myosin heavy chain gene duplications, losses, and the diversification of tail muscle cell identities in Oikopleura dioica

Following the conference it was incredible to visit Heron Island research station and have my first experience of fieldwork. Sampling for Oikopleura on the Great Barrier Reef is something I won't be forgetting anytime soon!

More excellent tunicate news this morning, with a new preprint from the @mchatzigeorgiou.bsky.social lab 🤩 This work, led by @olegtolstenkov.bsky.social, describes the fascinating diversity of behaviors displayed by the larvacean Oikopleura throughout its life cycle ⤵️🧪
New preprint from our lab: www.biorxiv.org/content/10.6... @olegtolstenkov.bsky.social, Sissel and Rodolfo in collaboration with @appygenetics.bsky.social @msarscentre.bsky.social built a behavioral atlas of the planktonic tunicate Oikopleura dioica across its life cycle.

Thanks Andre! Oikopleura is an amazing organism. Eric, Daniel (Chourrout) and Joel Glover have done some amazing work in the past and hopefully we can contribute as well...

I’m a bit of a newbie to plankton and I’ve seen a few this year but only seem to have photographed two - and only uploaded one - so guilty as charged! I’m guessing they are Oikopleura- maybe dioica?

Great contributions of our lab in #ESEB2025 with our research on genome architecture and gene regulation from an #oikopleura perspective.
Great organization

Peristaltic pumps are common in industrial and even in everyday settings. A cosmopolitan marine organism (the appendicularian, Oikopleura dioica), uses a novel peristaltic pump based on a tail that undulates inside a tightly fitting chamber. Nov. 2023 paper: doi.org/10.1098/rsif...

Sin entrar mucho más en detalle, parece ser que en Oikopleura "menos es más": la pérdida masiva de genes ha facilitado su adaptación evolutiva, expandiéndose y diversificándose los genes restantes.

Menos, pero más: entendiendo la pérdida de genes en la evolución
En la evolución de las especies, la pérdida de genes puede abrir nuevas oportunidades adaptativas a través de la expansión funcional de los restantes. En ello se basa la hipótesis de “menos, pero más”...

La pérdida de genes también puede afectar la evolución de otras regiones del genoma con las que antes interactuaba. Un ejemplo enigmático es Oikopleura dioica, un tunicado pariente cercano de los vertebrados cuyo genoma solo posee 70.000 nucleótidos (50 veces menos que nosotros).
