Heat map of genes differentially expressed between storage roots and fine roots of sweet potato, Ipomoea batatas (a) and Distimake dissectus (b). Each row in the heatmap is depicting the expression patterns of each transcript, and each column represents each library. A dendrogram illustrating clustering of libraries is shown above each heatmap, and a dendrogram showing clustering of transcript expression patterns is to the left of each heatmap. c Number of transcripts differentially expressed between storage and fine roots and the number that were orthologous between I. batatas and D. dissectus
