The expression of EF-Tu and Ts decreased with the culture time. A–D The relative EFs levels of four above mentioned bacteria were detected by qRT-PCR under the same nutrition conditions and times as Fig. 2E–H. The EFs levels were shown together with the translational ER of related strain in 1× T3SS-inducing conditions. The translational ERs at specific times were shown as green hollow symbols. The data at 0 min for each individual EF was set as 1. The standard deviations were shown but were very small in the plot. *p < 0.05; **p < 0.01; and ***p < 0.001. Results were indicated in mean ± SD. All experiments were repeated at least three times
