Figure 5

Network eQTL controlling a priori defined gene expression networks. The vertical lines separate the genome into chromosomes I-V (labeled at the top) with cM progressing left to right along the x axis, and the length of each chromosome in cM is at the end of each chromosome. The color schematic shows the LOD plot for each gene with the directionality of effect indicated by the color. Only significant QTLs are shown. A network eQTL where the Bay-0 allele has a positive effect is shown by differing shades of yellow and red, and darker intensity indicates a greater LOD score at that genetic position. A QTL where the Bay-0 allele has a negative effect is shown by differing shades of blue, again with darker intensity indicating a greater LOD score. The networks are ordered using median centered Spearman rank clustering of the effect traces along the genome; as a result, networks showing similar network eQTLs and effect directionality are located adjacent to each other. A. Network eQTL for gene expression networks obtained using mean-cis. B. Network eQTL for gene expression networks obtained using meanz.
