Figure 5. Biotic stress response overview map.

This figure shows the changes in the expression of biotic stress-responsive genes in A. thaliana plants during the response to the aphid and P. syringae treatments. Genes that have been experimentally indicated to be involved in biotic stress are collected in the main panel (coloured with dark grey), while genes and pathways that are putatively involved in biotic stress pathways are shown on the left and right sides (coloured in light grey). (A) Aphid infestation. (B) P. syringae infection. In both cases, the signal after infection is expressed as a ratio relative to the signal in uninfected controls, which was converted to a log2 scale and displayed. The scale is shown in the figures. Only the genes showing a significant (P = 0.01) change in expression between the treatment and the untreated control that were attributed to the respective bins by MapMan are shown. Genes whose expression was increased are indicated with increasingly intense blue and red colours. The gradation can be seen in the scale presented in the top right corner of each subfigure.
