CoReg analysis of the salicylic acid/rotenone module group from Nuclear Genes encoding Mitochondrial Proteins. The eight modules produced by ModuleFinder (Figure 3) were analyzed by CoReg. A) From the variety of elements detected in the upstream regions, five were selected which produced a tree structure that closely resembled the tree structure produced from the expression data. B) Hypothetical models of elements governing gene expression are shown based on these elements, which can be tested by experimental analysis. The sequences previously identified as regulatory elements in plants are indicated.
