Pearson Correlation Network Networks containing significantly correlated gene pairs (Pearson correlation coefficient > 0.95) that were modulated either up or down by heat stress. Nodes in cluster 1 (green) or cluster 2 (purple) were down-regulated in heat challenge while nodes in cluster 3 (gray) or cluster 4 (brown) were up-regulated. Red edges indicate positive correlation between gene pairs while blue edges indicate negative correlation.
