Fig. 2From: Quantitative proteomics reveals protein profiles underlying major transitions in aspen wood developmentJoint genotype effect scores from the Global PCA model. The PCA model includes data from all samples, from all four sampled trees. The score plots revealed clear progressive trends across the series of development zones in the sampled wood.
