Hierarchical clustering and principal coordinate analysis (PCoA) of transcriptomic and metabolomic profile. Hierarchical clustering of expression values (a) and metabolite content (c) at different sampled stages. Each column represents the mean value for each treatment at each sampled stage (5 and 7 days after cap fall (d)). Data were ln-transformed and yellow tones represent higher values while blue tones represent lower values. The strength of dendrogram nodes was estimated with a bootstrap analysis using 1000 permutations, values represented in the left side of internal nodes are the approximately unbiased p-values (AU), bold and italic values on the right side represented the bootstrap probability value. Principal Coordinate Analysis of expression values (b) and metabolite content (d) of control (triangles), GAc (circles) and shade (squares) treated inflorescences, at 5d (open) and 7d (close), and respective biological replicates. The variance explained by each coordinate (%) is given under brackets
