Fig. 1From: Metabolic profiling of maize seeds with both insect- and herbicide-resistance genes (cry1Ab and epsps), dual herbicide-resistance genes (epsps and pat), and natural genotypic varietiesMetabolite abundance pattern analysis. A Principal component (PC) analyses of metabolite levels in seeds of 7 maize lines. Score plot of the first two PCs with the explained variance. B Hierarchical clustering of 7 maize lines using metabolite accumulation data. In the heatmap, every repeat of each maize line is visualized in a single column. Metabolite accumulation is shown in different colours, where red indicates high abundance and green indicates low relative expressionBack to article page
