Figure 7

The relative expression of toxin-antitoxin systems in X. citri under stress. The relative expression of the genes XACa0028, XACa0027, XAC1499, XAC1501, and XAC4314 after temperature or copper stress in comparison to cells maintained at 28°C and without copper. The fold change data are presented in Log2. 16S gene expression was used as endogenous control. RT-qPCR reactions were repeated twice and each condition had three biological replicates. XAC4315 was not evaluated (ne). *indicates significant difference P ≥ 0.05 and **indicates significant difference P ≥ 0.01.
