Clytia hemisphaerica (Jellyfish, Z4C2) Assembly and Gene Annotation

About Clytia hemisphaerica

Clytia hemisphaerica is a hydrozoan–group cnidarian with both a colonial, vegetatively propagating polyp stage and free-living, sexual medusae. The evolutionary interest of the medusa lies in many complex features including striated muscle and sense organs that are absent in the polyp. In recent years, Clytia has helped answer questions including regulation of oocyte maturation, origins of embryo polarity and evolution of Hox genes and striated muscle.[1,2]

Assembly

The Clytia hemisphaerica (strain Z4C2) genome was sequenced and assembled by the MARIMBA (Marine Invertebrate Models Database) project.

The assembly was imported from GenBank.

Annotation

The Clytia hemisphaerica gene models were provided as GFF3 file by the MARIMBA (Marine Invertebrate Models Database) project. Non-coding RNA genes were added with the Ensembl Genomes RNA gene annotation pipeline.
