Involvement of different functional groups of Arabidopsis genes in host response against pathogens. Genes related to the general plant metabolism (black shaded columns): 1 – photosynthesis, 2 – mitochondrion, 3 – protein synthesis. Abiotic stress-responsive genes (clear columns): 4 – oxidative stress, 5 – cold, 6 – heat, 7 – water deprivation. Biotic stress-responsive genes (grey columns): 8 – fungi, 9 – bacteria. The ordinates represent a ratio between a fraction of functionally related genes in profile and a fraction of functionally related genes in the whole genome i.e. overrepresentation of the genes in the functional group as compared to the whole genome.
