Pharaoh Cuttlefish, Sepia pharaonis, Genome Reveals Unique Reflectin Camouflage Gene Set

Sepia pharaonis , the pharaoh cuttlefish, is a commercially valuable cuttlefish species across southeast coast of China and an important marine resource for world fisheries. Research efforts to develop linkage mapping, or marker-assisted selection have been hampered by absence high-quality reference genome. To address this need, we produced hybrid genome S. using long-read platform (Oxford Nanopore Technologies PromethION) assemble short-read, high quality technology (Illumina HiSeq X Ten) correct sequencing errors. The was assembled into 5,642 scaffolds with total length 4.79 Gb scaffold N 50 1.93 Mb. Annotation assembly identified 51,541 genes, including 12 copies reflectin gene, that enable control their body coloration. This new provides essential future studies biology, domestication selective breeding species.
