Here we present the genomes of P. dumerilii (laboratory culture reference and a single individual assembly) and of the closely related P. massiliensis and P. megalops (single individual assembly) to facilitate comparative genomic approaches and help explore Platynereis biology. We used long-read sequencing technology and chromosomal-conformation capture along with extensive transcriptomic resources to obtain and annotate a draft genome assembly of ~ 1.47 Gbp for P. dumerilii, of which more than half represent repeat elements. We predict around 29,000 protein-coding genes, with relatively large intron sizes, over 38,000 non-codBMC genomicsA genome resource for the marine annelid Platynereis spp.PMC12257675"EvoCELL" #766053DFG GZ TO 563/7-1HE 7224/8-1R35 GM138008NeuralCellTypeEvo #7889217889211R35GM138008-01ALTF 74-2018ANR- 11-LABX-0071ANR-19-CE27-0027-01Vellutini BCHercog RPeterson KJSimakov OOrdonez-Rueda DFromm BTomancak PAzevedo NHandberg-Thorsager MMutemi KNGazave EOzpolat BDLarsson THelm CArendt DHui JNull RWVervoort MLopez MOTan WProvaznik JPan LSantangeli LSavage EBenes VWinkler SfalseA genome resource for the marine annelid Platynereis spp.The marine annelid Platynereis dumerilii is a model organism used in many research areas including evolution and development, neurobiology, ecology and regeneration.
