Figure 1. Visualization and characterization of network architecture in relation to net photosynthesis. (A) Arabidopsis, soybean and Populus multi-dimensional scaling plots of co-expression network. The distance between circles is a function of topological overlap and provides a visual representation of gene and module relationships within network. Circled modules are enriched for genes participating in warming (e.g., heat shock protein and antioxidant enzymes). (B) The relationship between the expression of the warming module and net photosynthesis. Data from reference 5 produced a significant negative correlation between warming module expression and net photosynthesis (Pearson r = ^-0.82, p = 0.02). Note that data was not available at high temperatures compromising membrane integrity (dotted vertical line), so relationships beyond this point are entirely conceptual.
