Figure 6

Co-expressed genes network within the gene groups identified by comparative microarray approach (see Figure 3). Gene groups responsive to all tested rhizotoxins (Al, NaCl, Cd and Cu) and those uniquely induced by each stressor were analyzed to identify co-expressed gene networks by KAGIANA software, using a co-expression gene data set available in the ATTED-II database. Gene clusters were connected with lines if their Pearson's coefficient of correlation for gene expression was > 0.6 among 1388 microarrays from 58 experiments, which are available in the TAIR database. Other detailed information can be seen on the KAGIANA web site http://pmnedo.kazusa.or.jp/kagiana/. Some of genes in the cluster are colored according to their molecular functional annotations, and the characteristics of gene expression response reported by GENEVESTIGATOR are shown with various symbols (see low right of the Figure).
