Figure 2

Temporal resolution affects the interpretation of transcription profiles. The standardized mRNA abundance of four developmentally regulated genes (y-axis) is plotted versus time (hours, x-axis). Data are from the filter development experiment. For each gene—gtaC (A), csaA (B), cotB (C), and ecmB (D)—expression values are included for time points at 1-, 2- and 4-hour intervals, as indicated in the legend below the figure. Each data point represents the average of 2 independent biological replicates. The y-axis scale varies between plots. The insets in (C) and (D) highlight the 8 h – 12 h time frame.
