The genomic origin of the unique chaetognath body plan

An international group of researchers lead by Dr Piovani and Dr Marlétaz at UCL, in collaboration with Dr de Mendoza and Dr Martin-Duran from QMUL, has generated the first chromosome-level genome assembly for a chaetognath (arrow worm), an enigmatic animal group. Combining multiple functional genomic approaches, the researchers identified that chaetognath-specific genomic innovation underpins the evolution of many of the unique morphological and genomic traits of these fascinating worms.
