Figure 3From: Spatial gradients in cell wall composition and transcriptional profiles along elongating maize internodesPrincipal component analyses of internode microarray data. All genes (A) and genes involved in cell wall synthesis, re-modelling and degradation (B). MultiExperiment Viewer software was used for PCA and construction of the graphs (http://www.tm4.org).
