Grapevine transcripts showing plasticity at harvest. Principal component analysis of the whole third-stage dataset. The variables and scores scatter plot of the PCA model (nine components, R2X (cumulative) = 0.84, Q2 (cumulative) = 0.602) was generated using Simca P+ 13.0 and colored according to the disparity in the degree of ripening, as illustrated in Figure S7C (Additional File 15). Different vineyards are indicated by different symbols. Sample names are composed by vineyard abbreviation, followed by the indication of the harvesting year (08), by the indication of the developmental stage (3), and by the description of the biological replicate (A, B, or C).
