Trans-eQTL hotspots with at least 200 trans-eQTLs.

a,bIndicates the number of cis- and trans-eQTLs in each eQTL hotspot, respectively.cIndicates the number of eQTLs, where the B73 allele increased the expression level in the RIL population.dIndicates the number of eQTLs, where the Mo17 allele increased the expression level in the RIL population.eShows the significance level deviating from the random distribution between B73 and Mo17. The GO enrichments and the pathway enrichments of the regulated genes by hotspots were conducted using BiNGO plugin in Cytoscape based on the annotation information from AgriGO and MaizeCyc database, respectively. The results of GO enrichments and pathway enrichments are in Table S5 and Table S6, respectively.
