Genome of the lepidopleurid chiton Hanleya hanleyi (Mollusca, Polyplacophora).

ABSTRACT: Mollusca is the second most species-rich phylum and includes animals as disparate as octopuses, clams, and chitons. Dozens of molluscan genomes are available, but only one representative of the subphylum Aculifera, the sister taxon to all other molluscs, has been sequenced to date, hindering comparative and evolutionary studies. To facilitate evolutionary studies across Mollusca, we sequenced the genome of a second aculiferan mollusc, the lepidopleurid chiton Hanleya hanleyi (Bean 1844), using a hybrid approach combining Oxford Nanopore and Illumina reads. After purging redundant haplotigs and removing contamination from this 1.3% heterozygous genome, we produced a 2.5 Gbp haploid assembly (>4X the size of the other chiton genome sequenced to date) with an N50 of 65.0 Kbp.
