Enriched Gene Ontology (GO) biological process based on up-regulated genes at the three growth stages. Go enrichment analysis was performed based on the up-regulated genes between SP (traditional freestanding system) and DP (flat-type trellis system) at 45 DAF (A), 75 DAF (B) and 105 DAF (C), with p value < 0.001 as significant. DAF: day after flowering. The x-axis is the – log10 (p value). Color gradient from red-to-yellow indicates decreasing significance levels, i.e. red = most, orange = moderate, yellow = least significant. Red stars indicate the special interest Go terms. (D) Heat map showing the expression of up-regulated genes, which contribute to enrichment of these special interest GO terms, at the three growth stages. The red-to-blue scale represents a decreasing log2-fold change of gene expression in DP compared with SP system.
