Hierarchical cluster analysis (HiCA) heat map of the top 25 metabolites present in the averaged extracts (n = 9) showing the most and least abundant metabolites at each developmental stage (red/blue = high/low concentrations, respectively). The metabolites listed are as follows, respectively: 9,12,13-trihydroxy-10-octadecenoic acid (ODA-3OH(IV)), sinapoyl alcohol (sinapoyl-OH), 9,14-dihydroxy-10,12-octadecadienoic acid (ODA-2OH(II)), phenylalanine, trihydroxy-octadecadienoic acid (ODA-3OH(II)), riboflavin, octadecatetraenoic acid (OTA), tryptophan, traumatic acid, indole-3-acrylic acid, tyrosine, apigenin 7-O-neohesperidoside (rhoifolin) (apig-n), apigenin 6-C-xyloside-8-C-glucoside (vicenin-1), coumaroyl glucose (coumaroyl-glu II), sinapaldehyde glucoside II (sinapald-glu II), sinapaldehyde glucoside I (sin-glu), naringenin 7-O-neohesperidoside (naringin), hesperidin, indole-3-acetyl-leucine (IA-L), abscisic acid (ABA), naringenin 7-O-beta-D-glucoside (nar-glu), 1,3-O-coumaroyl-feruloylglycerol (CFG), luteolin 7-O-glucoside (Lut-glu), sophoraflavanone G (S-flavanone), coniferyl acetate (coniferyl-Ac).
