  1. Data are given as mean ± SD, n = 3. ** meant to have significant difference (P < 0.01) compared with the strain GC1. The transcriptional levels of all the genes in the GC1 strain were regarded as 100%. All the genes were mentioned in Table S2 and Fig. 1. Compared with those of the GC1 strain, *P < 0.05, **P < 0.01. The functions of all the genes are mentioned in Table 52
