The identification of candidate genes from the metabolomic dataset.
(A) Changes in molecular features (metabolites) associated with Chr8 ILs. Each green dot is an IL, red dot a molecular feature (putative metabolite). The black connecting lines show an increase, the blue a decrease. The cluster of features circled represents significant metabolite changes common to both 8-2 and 8-2-1, of which a reduction in γ-tocopherol and increase in α-tocopherol was observed. (B) LC-MS profile validating the identity of tocopherols. (C) Quantitative changes (± s.e.) in tocopherols (γ and α) found in IL8-2 and IL8-2-1, relative to their M82 comparator. (D) Co-localization of the candidate gene with the change in tocopherol metabolites in IL8-2 and 8-2-1, as well as the position of the candidate gene product within the tocopherol biosynthetic pathway.
