Figure 4.

Expression of genes involved in the reported abiotic stress responses. Figure shows those clusters that are the largest clusters having the given GO-term as their best GO-term (response to temperature stimulus is the best GO-term of Node_11728, response to heat of Node_11805 and response to water deprivation of Node_10337) (response to cold of Node_10952 is represented by a yellow square). Clusters sharing the same best GO-term as the largest cluster are coloured in purple in the expression tree. The table shows GO-terms that are related to abiotic functions (ABA is response to abscisic acid stimulus, Abiotic is response to abiotic stimulus, Temp is response to temperature stimulus, Heat is response to heat, Cold is response to cold and Water is response to water) and that are detected as significant within the set of clusters. Notations of the monitored experimental data sets are explained in Supplementary Table 1.
