sea lamprey - close-up of mouth Petromyzon_marinus_7.0 is an assembly of the sea lamprey (Petromyzon marinus) provided by the lamprey consortium. It was sequenced to a total of 5.0X whole genome coverage. The combined WGS and BAC-end sequence reads were assembled using Arachne V3.2. The expected genome size is 1.92 gb. The N50 size is the length such that 50% of the assembled genome lies in blocks of the N50 size or longer. The N50 size of scaffolds is 184.619 kb. The total of all scaffolds is 885Mb

The gene set for lamprey was built using the Ensembl pipeline. Gene models are based on genewise alignments of lamprey proteins and most proteins from Uniprot, whether vertebrate or more genetically distant species. The protein based gene models were then extended using lamprey cDNA. To improve the accuracy of models generated from distant species, transcriptome data was used to filter out the different gene models. In addition to the coding transcript models, non-coding RNAs and pseudogenes were annotated
