Figure 5

A correlation network of 7 metabolites and 36 candidate genes of the phenylpropanoid and flavonoid pathways in apple peel. Different figures represent metabolites – purple box; structural genes – grey ellipse; transcription factors inside the mQTL hotspot on LG16 – blue triangle; transcription factors on LG16, but outside the mQTL hotspot – yellow triangle; transcription factors elsewhere in the apple genome – pink triangle. Red connection lines represent negative correlations and green lines – positive correlations and thickness of the lines correspond to the standardized correlation coefficient rs.
