Fig. 4. Principal Component Analysis. Arrows represent the loading of the variables (table S3). Dots represent the score of each replicate on PC1 and PC2. Number of replicates from all tissues analyzed were 6 for young leaves from non-reproductive plants (L1), old leaves from non-reproductive plants (L3), inflorescences (F), and old leaves from reproductive plants (RL3), 10 replicates for leaves from seedlings (SD); and 5 for young leaves from reproductive plants (RL1). Compounds labelled as 1 (chicoric acid), 2 (caffeoylferuloyltartaric acid), 3 (p-coumaroylcaffeoyltartaric acid), 4 (coutaric acid) and 5 (di-p-coumaroyltartaric acid).
