TABLE 2.
Changes in expression levels of S. meliloti flagellum genes resulting from the exoR95 and exoS96 mutations, as determined in microarray hybridizations
| S. meliloti flagellum gene | Function | Change of gene expression in specific genetic backgrounda
|
|
|---|---|---|---|
| exoR95 mutant | exoS96 mutant | ||
| flaA (smc03037)b | Flagellin subunit | −4.3c | −3.3 |
| flaB (smc03038) | Flagellin subunit | −5.5 | −4.1 |
| flaC (smc03040) | Flagellin subunit | −3.0 | −2.7 |
| flaD (smc03039) | Flagellin subunit | −4.6 | −3.9 |
| flaF (smc03050) | Regulator | −3.3 | −3.8 |
a
The levels of the changes in gene expression were determined by comparing a particular gene in the mutant background versus expression in the wild-type background.
b
The open reading frame smc03037 stands for the number 03037 open reading frame on the chromosome of S. meliloti.
c
The value −4.3, for example, indicates that the expression level of the flaA gene was decreased 4.3-fold in the exoR95 mutant compared to that in the wild-type strain.
