Research efforts to develop linkage mapping, or marker-assisted selection have been hampered by the absence of a high-quality reference genome. To address this need, we produced a hybrid reference genome of S. pharaonis using a long-read Edited by: platform (Oxford Nanopore Technologies PromethION) to assemble the genome and Andrew Stanley Mount, short-read, high quality technology (Illumina HiSeq X Ten) to correct for sequencing Clemson University, United States errors. The genome was assembled into 5,642 scaffolds with a total length of 4.79 Gb Reviewed by: and a scaffold N of 1.93 Mb. Annotation of the S. pharaonis genome assembly Simo Njabulo Maduna, 50 Norwegian Institute of Bioeconomy identified a total of 51,541 genes, including 12 copies of the reflectin gene, that enable Research (NIBIO), Norway cuttlefish to control their body coloration.
