Transcriptomic response at puberty of Atlantic salmon testis tissue sampled from males fed a normal (NR) or restricted ration (RR; 43% of NR). a Total numbers of DEGs (N = 5–16, indicated by grey numbers; Student’s t-test, P < 0.01 at the α level of 0.05, FDR < 0.05; fold change > │1.5│) in each pairwise comparison. Numbers next to the brackets give the number of total DEGs. b Up- and down-regulated genes identified during male salmon maturation independently of the food regime (right panel), or exclusively in males exposed to the restricted ration (left panel). For each comparison, black and grey letters represent the test condition and its corresponding control, respectively. c Venn diagram representation of transcripts differentially expressed in all pairwise comparisons performed. For each comparison, black and grey letters represent the test condition and its corresponding control, respectively. d Stimulatory effect on testicular gene expression during puberty for a set of 449 shared genes (one-way ANOVA followed by Tukey’s test, *** P < 0.001 at the α level of 0.05), and modulation of the magnitude of this effect by the feed ration
