Figure 2.

Scatter plots showing distribution of POR gene expression ratios at different time points after inoculation. Each cDNA insert was replicated three times on the microarray slides (see “Materials and Methods”). The dots (>2-fold induction/repression) and white circles (<2-fold induction/repression) correspond to the signal intensity ratios (R11-12:R11-13) of the individual cDNA spots. The x axis represents the spot intensity of Cy3 (R11-12 RNA; experiment), and the y axis represents the spot intensity of Cy5 (R11-13 RNA; control). Diagonal blue and brown lines represent >2-fold and >10-fold induction:repression ratio cutoffs, respectively, relative to the best fit line through the normalized data (middle black line). Number of cDNA clones that are >2-fold or >10-fold induced (red)/repressed (green) is shown.
