  • Hydra magnipapillata full genome and have not been identified until now in other hydrozoan or scyphozoan species, being only known from the anthozoan

    PLoS ONE Alerts: New Articles

  • Although scyphozoan sequences are lacking in the HOX1, HOX2, HOX9-14A and CDX groups (figure 1), these absences could be due to non exhaustive sampling from PCR surveys, a full genome sequence being currently lacking for this cnidarian lineage

    PLoS ONE Alerts: New Articles

  • In some cases, gene relationships among cnidarian groups are congruent with the species phylogeny: hydrozoan sequences are sister-group to scyphozoan sequences, with anthozoan sequences branching basally to this ensemble.
