Fig. 8

Volcano plot of differentially expressed contigs in the acaricide resistant PSR-TK strain relative to the susceptible HS strain. The negative log₁₀ of Benjamini-Hochberg (BH) adjusted p-values was plotted against the log₂FC in gene expression. P. ulmi contigs up- and downregulated, by twofold or more (123 and 122 genes, respectively) are depicted as light grey circular dots. Circular dots of various colours depict contigs with a best BLASTx hit with T. urticae proteins putatively involved in xenobiotic detoxification ([36], see also Additional file 17). Contigs encoding detoxification genes putatively involved in spirodiclofen resistance are indicated in the plot by ID PuP450_18 (contig_01016, log₂(FC) = 5.1, BH adjusted p-value = 1,1E⁻¹⁹³) and ID PuCCE_7 (contig_00577, log₂(FC) = 5.1, BH adjusted p-value =1,4E⁻²⁵⁷)
