Fig. 2From: Cellular and transcriptomic analyses reveal two-staged chloroplast biogenesis underpinning photosynthesis build-up in the wheat leafBiologically informed global gene expression program of the first leaf of wheat. a Principal component (PC) analysis (PCA), displaying the first two components of variance among each biological replica of each sample. b PCA displaying the first three components. Samples colored as in a. Ontology terms associated with the genes with the highest load in each direction of each PC are indicated in the corresponding axis. c Heatmap (red, high; blue, low) of the expression (Z-score) of 42,057 dynamically expressed genes (DYGs), grouped in clusters (modules 1–12) as identified by WGCNA, and ordered by timing of peak expression. Some selected, overrepresented functional classification terms (displayed in d) are included. d Probability (displayed as the inverse of the log10) of over/underrepresented functional classification terms of each gene cluster displayed in cBack to article page
