However, our understanding of the genetic mechanisms underlying various aspects of their reproductive biology, including sex determination, are still lacking. This is partly due to the scarcity of genomic resources for Artemia species and crustaceans in general. Here, we present a chromosome-level genome assembly of Artemia franciscana (Kellogg 1906), from the Great Salt Lake, USA. The genome is 1GB, and the majority of the genome (81%) is scaffolded into 21 linkage groups using a previously published high-density linkage map. We performed coverage and FST analyses using male and female genomic and transcriptomic reads to quantify the extent of differentiation between the Z and W chromosomes. Additionally, we quantified the expression levels in male and female heads and gonads and found further evidence for dosage compensation in this species. https://research-explorer.ista.ac.at/download/14705/14707/readme.txt.txt text/plainno https://research-explorer.ista.ac.at/download/14705/14708/data_artemia_franciscana_genome.zip application/x-zip-compressedno https://creativecommons.org/licenses/by/4.0/ Institute of Science and Technology Austria2024 sex chromosome evolutiongenome assemblydosage compensation 10.15479/AT:ISTA:14705 https://research-explorer.ista.ac.at/record/15009 M.N.
