Hierarchical cluster analysis for indentifying correlated genes. Detail of the heatmap and cluster analyses where C2 lactones (in red) are found. For each gene, the id and the unigene annotation are provided. Three replicates per maturity stage are shown. Data are expressed as a log2 of a ratio (sample/common reference). The gene annotated as “0.00E+00” indicate that either no homologue was found or the homologue found has unknown function. For a detailed description of ChillPeach unigene functional annotation see Ogundiwin et al. .
