Procambarus clarkii Genome sequencing

The red swamp crayfish Procambarus clarkii (Girard, 1852), native to the southern United States and northern Mexico, has attracted considerable research attention owing to its importance in aquaculture, as well as its significant ecological impact as an invasive species. Here, we present a chromosome-scale genome assembly for P. clarkii, generated using a combination of Illumina, PacBio and Hi-C sequencing. To address these key questions related to its invasion success, we performed detailed analyses of the genome organization and the evolution of gene families implicated in feeding, detoxification and immunity.
