Comparative map illustrating the position of qPE8.1 for seed phorbol esters content in the F₂ population of Chai Nat × M10 identified in this study (right) and the location of locus controlling seed phorbol esters in the F₂ population of G33 × G43 reported by King et al. [12] (left). Lines connect common markers between the two maps. Small solid bars along the maps indicate confidence intervals of the locus detected for seed phorbol esters. The QTL for PE reported by King was initially mapped between markers JCT3 and 1401433/12335072 by considering the PE as a quantitative trait. The PE locus was then fine mapped between markers NG285A and G273A by considering PE as a qualitative trait. Three solid bars along the map of Chai Nat × M10 represent Jatropha reference sequence from Jatropha curcas Database (JCDB).
