Fig. 5.

Differential protein expression in salivary glands between PMD-R and UPK-R strains. Differences in protein expression are represented as expression ratio or fold expression (UPK-R /PMD-R UPK-R). Horizontal dot lines indicate the 2-fold difference in expression level in either direction (2 for a higher expression in the UPK-R strain and -2 for a lower expression in the UPK-R strain). Proteins showing significantly different more than or less than 2-fold expression (Student’s t-test, P ≤ 0.05) are indicated by an asterisk (*). The ANV of each major protein and their fold expression values are shown in Additional file 5: Table S4
