The entire sequence of each gene was used in the analysis. Correlation coefficients ranked significantly higher among all interaction pairs are indicated with “+” sign. Coefficients that are not ranked significantly higher are indicated with “−” sign. “pt” is the group of control genes from the plastid genome, and “nu” is the group of control genes from the nuclear genome. Results of the average by all method (ρava), average by separation method (ρavs), and PCA method (ρpca) are shown. Results from average method were estimated in two ways (all/separate; see Methods).
