Bayesian hierarchical clustering of the CRKs in abiotic and biotic stress experiments. Biotic and abiotic stress data sets were down loaded from public databases and included O₃, norflurazon, paraquat, BTH (benzothiadiazole S-methylester), various elicitors and pathogens (see materials and methods for complete details). Red and green indicate increased or decreased expression compared to untreated plants, respectively. The intensity of the colours is proportional to the absolute value of the fold difference.
