Hierarchical cluster analysis for identifying the genes correlating with the 52 VOCs. A) The heatmap and cluster analyses of the gene-volatile data set (4348 genes and 52 volatiles). Three replicates per stage are shown. Data are expressed as the log2 of a ratio (sample/common reference). B) Details of the HCA where volatile compounds are present with genes. Volatiles are indicated with a red letter. For each gene, the id and unigene annotation and identifier are provided (in parentheses) when available. Three replicates per stage are shown. Sub-clusters are named according to the volatile members that they have. For example, the volatiles of C1, according to Figure  1, appear in three sub-clusters named C1.1, C1.2, and C1.3.
