Figure 1. Regulation of CrcZ and CrcX in P. syringae. Relative levels of the crcZ and crcX ncRNAs, compared to WT, measured by quantitative RT-PCR, in cells grown overnight in KB medium. The levels of gene expression in each sample were calculated as fold expression ratio using gyrA as a gene for normalization. The values are averages of three independent experiments and error bars represent standard deviation.
