The Whole Genome Sequence and mRNA Transcriptome of the Tropical Cyclopoid Copepod .

Copepoda is one of the most ecologically important animal groups on Earth, yet very few genetic resources are available for this Subclass. Here, we present the first whole genome sequence (WGS, acc. UYDY01) and the first mRNA transcriptome assembly (TSA, Acc. GHAJ01) for the tropical cyclopoid copepod species Until now, only the 18S small subunit of ribosomal RNA gene and the COI gene has been available from , and WGS resources was only available from one other cyclopoid copepod species. Overall, the provided resources are the 8 copepod species to have WGS resources available and the 19 copepod species with TSA information available. We analyze the length and GC content of the provided WGS scaffolds as well as the coverage and gene content of both the WGS and the TSA assembly. Finally, we place the resources within the copepod order Cyclopoida as a member of the genus. We estimate the total genome size of to 450 Mb, with 181 Mb assembled nonrepetitive sequence, 76 Mb assembled repeats and 193 Mb unassembled sequence. The TSA assembly consists of 29,737 genes and an additional 45,756 isoforms. In the WGS and TSA assemblies, >80% and >95% of core genes can be found, though many in fragmented versions. The provided resources will allow researchers to conduct physiological experiments on , and also increase the possibilities for copepod gene set analysis, as it adds substantially to the copepod datasets available.
