TPSAB1 and infection: We demonstrated that any Wolbachia strain reduced the expression of the tps1 gene (coding for an enzyme for trehalose synthesis from glucose) but did not affect the expression of the treh gene (coding for an enzyme that degrades trehalose to produce glucose) in all infected lines (Figure 4a, infection—H(3.8) = 9.435, p = 0.02 for tps1; and Figure 4b, infection—H(3.8) = 0.598, p = 0.47 for treh).
