| Title |
Expression analysis of Caulobacter crescentus NA1000 bearing a CCNA_00690 (cdnL) deletion [dcdnL] vs Caulobacter crescentus NA1000 wild type [wt] |
| Organism |
Caulobacter vibrioides NA1000 |
| Experiment type |
Expression profiling by array
|
| Summary |
Investigation of whole genome gene expression level changes in a Caulobacter crescentus NA1000 dcdnL mutant, compared to the wild-type strain.
In bacteria, transcription of housekeeping genes required for metabolic homeostasis and cell proliferation is guided by the sigma factor σ70. The conserved CarD-like transcriptional regulator, CdnL, associates with promoter regions where σ70 localizes and stabilizes the open promoter complex. Caulobacter crescentus cells lacking CdnL have severe morphological and growth defects. Our microarray experiment demonstrates how cdnL deletion affects the transcriptome of Caulobacter crescentus.

| Overall design |
A six chip study using total RNA recovered from three separate wild-type cultures of Caulobacter crescentus NA1000 and three separate cultures of a mutant strain, Caulobacter crescentus NA1000 dcdnL (deletion of CCNA_00690), in which the cdnL gene coding for an RNA polymerase associated factor is deleted. Each chip measures the expression level of 3933 genes from Caulobacter crescentus NA1000 with 3 probes per gene and with three-fold technical redundancy.
