3.3.4 Comparisons between tissue type within the same sampling
groups
We found that blood and muscle have the lowest number of genes with
detected expression in both tissues compared to the other pairwise
tissue comparisons (Tables S2 and S4 on Dryad). We observed differences
in gene expression among tissue types (blood, muscle, gills) for each of
the sampling methods. Of all the genes that are significantly
differentially expressed (adjusted p - value <0.05)
among tissue types, only 25-32% are more highly expressed in blood
compared to gill and muscle (Tables S2 and S4 on Dryad). Conversely, the
proportion of significantly differentially expressed genes in gill and
muscle was much more even and within ±10 of 50% (Tables S2 and S4 on
Dryad).
