FIGURE 7.

Organ-specific expression of poplar DQD/SDHs and QDHs (A), their response to changing environmental factors (B), and their response to genetic perturbations (C). Publicly available large-scale microarray expression data for any Populus species were compiled, normalized, and grouped based on experiment annotations. Log-transformed expression ratios were visualized as heatmap. Organ expression data are shown relative to the mean expression of the respective gene across all experiments, treatment and mutant expression data are shown relative to the respective control experiments. Detailed descriptions of each sample and database accessions for the respective datasets can be found in supplemental Table 1.
