Comparative analysis of transcriptome and proteome data and spCCA analysis. a, b, c, and d Correlation between transcript and protein fold-changes upon Pi-deficiency. a For each genotype, all significantly regulated proteins (p ≤ 0.05) were plotted against its cognate transcript, if present on the ATH1 chip. b, c, and d Significantly (p ≤ 0.05) regulated protein/mRNA pairs were plotted against each other. Scatter plots show 26 protein/mRNA pairs regulated in wild-type upon Pi-deficiency, 211 pairs identified for pdr2, and 21 pairs identified in lpr1lrp2. e Correlation (r) values for each pairwise comparison. Asterisks indicate significance for each correlation analysis (p < 0.0001). f, g Canonical variables of the spCCA analysis representing a subset of transcripts/proteins which showed maximum correlation with the illustrated patterns that were generated by the spCCA algorithm.
