pQTL profiles of seven selected signalling pathway proteins.

<p>Blue curves show the significance of the pQTLs multiplied by the sign of the effect of the N2 allele (positive values of blue curve indicate higher protein abundance when the N2 allele is present, whereas negative values indicate higher protein abundance when the CB4856 allele is present). Horizontal orange and red dashed lines show 0.1 and 0.05 FDR thresholds respectively. Vertical dotted grey lines separate chromosomes I to V and X from left to right. Vertical magenta bands indicate the position of the gene in the genome. PSR-1 shows a significant pQTL on the left arm of chromosome II.
