FIG 4.

Transcript levels of select gene candidates in response to U. C. crescentus cells were grown in buffered PYE medium to early exponential phase and were either untreated (black bars) or spiked with 350 μM uranyl nitrate (gray bars). Samples were collected 30 min after spike-in, and transcript levels were determined by NanoString analysis. Log₂ expression values are presented, and error bars represent standard deviations from three biological replicates. Transcripts significantly upregulated are highlighted with asterisks (*, P < 0.01).
