Habitat-specific gene expression in stickleback immune tissues from four parametric lake-river population pairs

Experiment ID:ERP009696
Technology:RNA-Seq
Description:The three-spined stickleback (Gasterosteus aculeatus) has repeatedly colonized and adapted to diverse freshwater habitats since the last glaciation. Among those freshwater habitats, adjacent lake and river populations harbour distinct parasite communities, a recurring ecological difference proposed to drive adaptive differentiation between lake and river stickleback ecotypes. To study the rapid adaptation of sticklebacks to lake and river habitats, we analysed gene expression profiles of 77 whole-transcriptome libraries of two immune-relevant tissues, the head kidney and the spleen, obtained from wild-caught sticklebacks of the two habitat types across multiple geographic locations. Differential expression analyses identified 189 genes showing statistically significant habitat-specific expression patterns among the three European locations. Among those genes, 15 genes are annotated with putative immune functions, and 50 have been experimentally associated with immune-responses in sticklebacks, reinforcing the hypothesis that parasites contribute to adaptive evolution of lake and river sticklebacks. Comparing expression profiles of European sticklebacks to populations in similar habitats in North America, five genes exhibited habitat-specific expression across continents.

Total read count
Total number of reads for the library.
Mapped read count
Number of reads that could be mapped to the transcriptome.
Total UMI count
Total number of individual RNA molecules (UMI) for the annotated sample. Only applicable for libraries producing UMIs.
Mapped UMI count
Number of UMIs that could be mapped to the transcriptome. Only applicable for libraries producing UMIs.
Distinct rank count
When performing a fractional ranking of the genes in the annotated sample, based on their expression level, number of distinct ranks observed, to have a value of the power for distinguishing expression levels. Used as a weight to compute a weighted mean rank accross samples for each gene and compute expression scores in Bgee.
Max rank
When performing a fractional ranking of the genes in the annotated sample, based on their expression level, maximum rank attained in the sample. Used to normalize ranks accross samples and compute expression scores in Bgee.
