Chrysaora quinquecirrha high-continuity genome annotation data

The Atlantic sea nettle (Chrysaora quinquecirrha) has a key evolutionary
position due to its high ecological value. However, the published
C.quinquecirrhagenome assembly is very fragmented, due to limited
sequencing technologies and the complicated jellyfish genomic sequence.
Here, we used the most advanced high-through chromosome conformation
capture technology to get high-coverage sequencing data of the
C.quinquecirrha genome. Then we anchored these data to the previously
published contig-level genome assembly to improve its genome. Finally, a
high-continuity genome sequence of C.quinquecirrha was successfully
assembled, which contained 1,882scaffoldswith a N50 length of 3.83 Mb. The
N50 length of this version of the genome assembly is 5.23 times longer
than the previously released one, and additional analysis revealed that it
has a high degree of genomic continuity and accuracy. Acquisition of the
high-continuity genome sequence of C.quinquecirrha not only provides a
basis for the study of evolution in jellyfishes through comparative
genomics, but will also provide an important resource for studies on its
growth and development.
