Homeodomain transcription factors are involved in many developmental processes across animals and have been linked to body plan evolution. Detailed classifications of these proteins identified 11 distinct classes of homeodomain proteins in animal genomes, each harboring specific sequence composition and protein domains. Although humans contain the full set of classes, Drosophila melanogaster...

An emerging system to study photosymbiosis, brain regeneration, chronobiology, and behavior: the marine acoel symsagittifera roscoffensis

Arboleda, Enrique ; Hartenstein, Volker ; Martinez, Pedro ; Reichert, Heinrich ; Sen, Sonia ; Sprecher, Simon ; Bailly, Xavier

In: BioEssays, 2018, vol. 40, no. 10, p. 1800107

The acoel worm Symsagittifera roscoffensis, an early offshoot of the Bilateria and the only well-studied marine acoel that lives in a photosymbiotic relationship, exhibits a centralized nervous system, brain regeneration, and a wide repertoire of complex behaviors such as circatidal rhythmicity, photo/geotaxis, and social interactions. While this animal can be collected by the thousands and...

Functional brain regeneration in the acoel worm Symsagittifera roscoffensis

Sprecher, Simon G. ; Bernardo-Garcia, F. Javier ; Giesen, Lena van ; Hartenstein, Volker ; Reichert, Heinrich ; Neves, Ricardo ; Bailly, Xavier ; Martinez, Pedro ; Brauchle, Michael

In: Biology Open, 2015, vol. 4, no. 12, p. 1688–1695

The ability of some animals to regrow their head and brain after decapitation provides a striking example of the regenerative capacity within the animal kingdom. The acoel worm Symsagittifera roscoffensis can regrow its head, brain and sensory head organs within only a few weeks after decapitation. How rapidly and to what degree it also reacquires its functionality to control behavior however...
