Cross-substrates comparison of ortholog expression patterns. a Symmetrical heat map of Spearman’s correlation coefficients between all samples across all single-copy orthologs. Correlation coefficients are shown on the left ranging from blue (low similarity) to red (high similarity) (b) PCA of the log-transformed normalized expression levels of the single-copy orthologs between the two species grown in the canga and forest substrates. Species are represented by point shape; substrates are represented by point color
