  1. Number of lice included in each group (n) is provided in Table 1
  2. Notes: Upregulation is indicated as log2FC positive values; downregulation as log2FC negative values. Statistical significance is indicated in bold (P(adj) values). ENSEMBL L. salmonis transcriptome was used in the analysis, but the sequences of genes coding for aquaporins were replaced by GenBank entries: Catalase, EMLSAT00000007315; DNA-polymerase, EMLSAT00000002584; Nesprin-like, EMLSAT00000005972; NA (unannotated), EMLSAT00000005947; ERP29, EMLSAT00000009549; Glp1_v2, KR005661.1; Aqp12L1, KR005665.1; Aqp12L2, KR005666.1; Glp2, KR005662.1; Glp3_v1, KR005663.1
  3. Abbreviations: Ls A/F2-S, sensitive lice; Ls V/F2-R, resistant lice; SD, standard deviation; Log2FC, log2 fold change; P(adj), P-value for normalized counts (α = 0.05)
