Expression QTL analysis in epiRILs. (A) AT2G03070 and (B) AT3G24360. RNA was extracted for 93 epiRILs, reverse-transcribed to cDNA, and quantified by SYBR Green qPCR. Gene expression was normalized against the reference gene TIP41 and subjected to eQTL^epi analyses. Green line indicates LOD significance threshold that was calculated using 1000 random permutations with α 0.05 as the genome-wide type 1 error level. Markers positions are indicated on the bottom of the graph.
