Principal component analysis (PCA) score plot of samples based on modified principal components. a The space defined by mPC1, mPC2, and mPC3. A three-dimensional model allowing interactive rotation is available in additional file 4. See Supplemental Figure 4 for the PCA score plot based on the original principal components. b The space defined by mPC1 and mPC2. The gray arrow represents the regression curve for the distribution of samples in this space. c The space defined by mPC1 and mPC3. The proportions of the total variance explained by mPC1, mPC2, and mPC3 are shown in parentheses. Samples collected at the same stage are shown in the same color. Samples with different tissue identities are indicated by different symbols: shoot apex, square; P3 leaf, circle; blade, triangle; blade-sheath boundary, diamond; sheath, inverted triangle
