Differential expression profiles of phylogenetically closely related <i>FBA</i> genes.

<p>A, Mean expression values for unstable and stable <i>A. thaliana FBA</i> genes extracted from AtGenExpress_Plus-extended_tissue_series <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0068672#pone.0068672-Toufighi1" target="_blank">[42]</a>. Error bars represent SE. Statistical significance was assessed using Student´s t-test (***P<0.001). B, NJ tree of 211 <i>A. thaliana</i> FBA proteins based on amino acid sequence homology. C, Clustering of 102 <i>A. thaliana</i> FBA proteins based on co-expression data from the AtGenExpress_Plus-extended_tissue_series. Discrepancy in the number of FBA genes/proteins between the trees in A and B results from 109 missing <i>FBA</i> genes on the ATH1 microarray. Two clades were selected for which all genes had representatives in the ATH1-Chip for illustration purposes (highlighted in green and red font). All other genes were collapsed and labeled according to the number of <i>FBA</i> genes within the respective branches.
