摘要

Objective

The Cuban Painted Landsnail is an iconic endemic tree snail species with distinctive colourful shells used in traditional handicrafts. This species won the International Mollusc of the Year 2022 competition in an open public vote. As the competition prize, we have assembled the draft genome of this species.

Data description

Genomic DNA from Polymita picta (Born, 1778) was sequenced using PacBio HiFi sequencing with a yield of 5.3 million reads (41.4 Gb) and an N50 of 8.1 Kb. The genome size of P. picta was estimated to be 2.9 Gb, and the final assembly was 1.85 Gb, with a total of 22,619 contigs and a contig N50 of 124.2 Kb. BUSCO analysis of the genome assembly indicated a genome completeness of 88.4%, with 7% complete duplicated BUSCOs in metazoa_odb10. The draft genome will be a valuable resource for work on the endangered Cuban Painted Landsnail including monitoring genetic diversity and establishing captive breeding for conservation.
