Figure 4.

Response of the pho1 and pho3 mutants visualized on a nutrient response map. For both pho1 and pho3 mutants, the response to the wild type was calculated as a log ratio. The results were displayed on a response map showing the hundred most up- or down-regulated genes of Arabidopsis in response to different starvation conditions. In the case where a similar response is encountered, the individual spots in an area should have the same color as the guide bars in the same column.
