Figure 7

Heat map showing MtARF genes expression pattern at the early phase of S. meliloti infection in wild-type A17 and mutant dmi3. Samples of two different tissues (shoots and roots) were used to test the changes of MtARF genes expression level at different time points (6, 12, 24, 48, 72 hpi). The different colors correspond to the values of the gene expression changes shown in the bar at the right of figure. The red color represents up-regulation expression, black represents unchanged expression level and green color represents down-regulation expression.
