Hierarchical cluster analysis with Pearson correlation using a pairwise average-linkage clustering method, comparing the relative proportion of each acylsugar fatty acid by entry.

<p>Relative proportion of a fatty acid’s accumulation compared among the thirteen entries, excluding Mt. Spring, is shown. Color across a row indicates the relative proportion of an individual fatty acid as compared to all the other entries, but does not reveal the total amount of acylsugar fatty acid (see Panel B in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201583#pone.0201583.g002" target="_blank">Fig 2</a> for this information). Comparisons within an entry column are not relevant, because the colors do not infer total amounts or relative proportion of each fatty acid within an entry (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0201583#pone.0201583.s002" target="_blank">S2 Fig</a> for this information). Dark red indicates that the percent accumulation of a fatty acid is the highest compared to the other entries in the row. Dark blue indicates that the percent accumulation of a fatty acid is the lowest (or absent) compared to the other entries in the row. Shade increase from dark blue through dark red indicates increasing percent accumulation of that particular fatty acid across the entries. Thus, the similarities and differences among entries for an individual fatty acid are shown by looking at the colors across a row.
