Transcriptomic analysis of the A. deserti leaf proximal-distal axis. (A) One of the A. deserti leaves used for analysis, indicating proximal-distal (PD) sections 1–4. (B) Six major K-means clusters of gene expression along the PD axis. Clusters are grouped by highest expression in proximal, medial, or distal tissues. Blue lines connect mean z-scaled RPKM values, shaded areas represent the 25th and 75th percentiles. Green text beneath each cluster denotes the most significantly enriched GO term in each cluster. (C, D) Heatmaps of composite gene expression for indicated biological processes. Data supporting figure are in Additional file 2. See text for details.
