From: Transcription-associated metabolomic profiling reveals the critical role of frost tolerance in wheat
Correlation network analysis of differential metabolites and differential expression genes related to frost tolerance in wheat. The red lines indicate positive correlation; the green line indicates negative correlation, the blue line indicates the correlation is not significant. Metabolites were marked red, structural genes were green. The size of the red circle represents the number of genes associated with the metabolite. The thickness of the ring frame of metabolite group was adjusted to indicate the differential multiple of metabolites. The line thickness between nodes represents the degree of correlation between two nodes
