Extant deep-sea invertebrate fauna represent both ancient and recent invasions from shallow-water habitats. Hydrostatic pressure may present a significant physiological challenge to organisms seeking to colonize deeper waters or migrate ontogenetically. Pressure may be a key factor contributing to bottlenecks in the radiation of taxa and potentially drive speciation. Here, we assess shifts in the tolerance of hydrostatic pressure through early ontogeny of the northern stone crab Lithodes maja, which occupies a depth range of 4–790 m in the North Atlantic. The zoea I, megalopa and crab I stages were exposed to hydrostatic pressures up to 30.0 MPa (equivalent of 3000 m depth), and the relative fold change of genes putatively coding for the N-methyl-d-aspartate receptor-regulated protein 1 (narg gene), two heat-shock protein 70 kDa (HSP70) isoforms and mitochondrial Citrate Synthase (CS gene) were measured. This study finds a significant increase in the relative expression of the CS and hsp70a genes with ... : Narg FASTA files for alignmentFASTA format files used to derive the narg gene alignmentNarg_FASTA_files_for_alignment.txtClustalO narg alignmentClustal Omega alignment file for the narg geneclustalo_narg_alignment.clustalRpl8 FASTA files for alignmentFASTA files used to derive the rpl8 alignmentRpl8_FASTA_files_for_alignment.txtClustalO rpl8 alignmentClustal Omega download file for rpl8 alignmentclustalo_rpl8_alignment.clustalTubulin FASTA files for alignmentFASTA files used to derives Tubulin gene alignmentTubulin_FASTA_files_for_alignment.txtClustalO tubulin alignmentClustal Omega download for tubulin gene alignmentclustalo_tubulin_alignment.clustalEef1a FASTA file alignmentsFASTA files used to derive eef1a gene alignmentEef1a_FASTA_file_alignments.txtClustalO eef1a alignmentClustal Omega download for eef1a gene alignmentclustalo_eef1a_alignment.clustalCS FASTA files for alignmentFASTA files used to derive CS gene alignmentCs_FASTA_files_for_alignment.txtClustalO cs alignmentClustal Omega download file for ...
