Pairwise correlations of gene expression between the four genotypes: Eichhornia paniculata - Brazil, Jamaica and Nicaragua and Eichhornia paradoxa. Above the diagonal are the correlation coefficients for data plotted below the diagonal. Each pair below the diagonal is expression level plotted on a log scale, measured in FPKM, which estimates gene expression from the number of reads that are derived from each transcript in our samples. All correlations are significant at P < 0.00001.
