Salmonella wild type and mutant sdiA in LB and 2mM indole

Transcriptional profiling of Salmonella Typhimurium SL1344 wild type and deletion of the sdiA regulator-encoding gene grown to OD600=1 in LB alone or in LB supplemented with 2mM indole. The goal is to determine Salmonella response to indole and to define the SdiA-regulated genes in these conditions. 4 different conditions tested (wild type in LB, wild type in LB + 2mM indole, sdiA mutant in LB, sdiA mutant in LB + 2mM indole), 4 replicates for each condition. The reference on each hybridisation is the chromosomal DNA of the wild type strain.
