Genetic architecture of rice secondary metabolism.
(a) Manhattan plot for genome-wide association mapping of rice metabolic phenotypes. SNPs significantly associated with some metabolite levels were plotted on the rice genome (α = 1.0 × 10−3).
(b) Associations between 3168 SNPs aligned on the upper boundary and 342 metabolites aligned on the lower boundary. Positions of SNPs correspond to the above panel. Red, blue, and gray lines represent significant associations between SNPs and metabolites with threshold levels of α = 1.0 × 10−5, 5.0 × 10−5, and 1.0 × 10−3, respectively. Positions of metabolite clusters and representative metabolites are also represented (Table S4 for metabolite names).
