Fig. 7. Effect of RydD on gpmA and sodB expression upon shifts between aerobic and anaerobic conditions.

Fig. 7

MG1655 and MG1655 ΔfnrS strains were grown in M63 with 0.2% glucose and 40 mM fumarate to OD600 ≈ 0.4 under aerobic conditions. Cells were collected and resuspended in the same medium and grown anaerobically. After 20 min, cells were again harvested, resuspended in the same medium and incubated aerobically for 60 min. Total RNA was extracted at several times (min) during this cycle. Northern blots were probed as in Fig. 2 and 4 for the genes indicated on the right.
