Genome-wide expression in exponentially growing V. parahaemolyticus determined by cDNA/gDNA microarrays. Gene expression was determined by comparing cDNA generated from cells in exponential phase (OD600 ~ 0.5) grown in LB with 3% NaCl at 37°C (A) or 20°C (B) or in M9 with 3% NaCl supplemented with 0.4% glucose (C) against gDNA from non-replicating cells. Results are presented as black trend-lines that show sliding averages for 50 data points. Trend-lines from the previous gDNA quantifications (in grey) are included for comparison. Numbers display ori/ter ratios determined by linear regression analyses on expression data plotted against distances from the origin of replication. Scales on the x-axes display approximate chromosomal lengths.
