Expression analysis of Caulobacter crescentus NA1000 bearing a CCNA_00690 (cdnL) deletion [dcdnL] vs Caulobacter crescentus NA1000 wild type [wt]

Project description: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.

Expression analysis of Caulobacter crescentus NA1000 delta-CCNA_00382 (ccrM) [DccrM] vs Caulobacter crescentus NA1000 wild type [WT]

Project description:Investigation of whole genome gene expression level changes in a Caulobacter crescentus NA1000 delta-CCNA_00382 (ccrM) mutant, compared to the wild-type strain. The mutations engineered into this strain render it incapable of methylating its genome on the adenine at GANTC motifs.

A six chip study using total RNA recovered from three separate wild-type cultures of Caulobacter crescentus NA1000 and three separate cultures of a triple mutant strain, Caulobacter crescentus NA1000 delta-CCNA_00382 (ccrM), in which the ccrM gene coding for a DNA methyltransferase methylating the adenine in GANTC motifs is truncated and its product inactive. Each chip measures the expression level of 3933 genes from Caulobacter crescentus NA1000 with 3 probes per gene and with three-fold technical redundancy.

Expression analysis of Caulobacter crescentus NA1000 Plac::CCNA_00382 (ccrM) vs Caulobacter crescentus

Project description:Investigation of whole genome gene expression level changes in a Caulonacter crescentus NA1000 Plac::CCNA_00382 (ccrM) mutant, compared to the wild-type strain. The mutations engineered into this strain cause the CcrM DNA methyltransferase to be overexpressed and the chromosome to be constitutively methylated at the adenine at GANTC motifs.

Comparing the transcriptional profiles of a Caulobacter crescentus CB15N (NA1000) wild-type to a SpoT null in carbon starvation.

Project description:SpoT is an Rsh (Rel / Spo homolog) protein, which synthesizes the alarmone ppGpp in response to starvation. This experiment is quantifying transcription in two Caulobacter strains after 5 minutes of glucose starvation: one strain is wild-type CB15N (NA1000); the other strain is NA1000 which has a chromosomal in-frame deletion of the spoT gene. The wild-type strain can synthesize the alarmone ppGpp in response to starvation and the spoT null strain cannot. Both strains were cultured in M2 defined medium with glucose as the sole carbon source, and then washed and incubated in M2 medium lacking glucose for 5 minutes before RNA isolation. Triplicate cultures of: 1) C. crescentus strain CB15N , and 2) CB15N ?SpoT, cultured in M2-glucose media, then starved for glucose for 5 minutes.
