Figure 1. Clustering of protein levels along the maize leaf growth zone.
A QT-Clust analysis (Heyer et al ., 1999) was used to cluster a total number of 230 proteins with significantly differential levels (FDR < 0.05, one-way ANOVA), between the three developmental zones (meristem, elongation zone, and mature zone). Euclidian distance, cluster diameter = 0.4, and minimum cluster population = 4 were used in MeV (Saeed et al ., 2003) to generate the clusters.
