Fig. 5From: Transcriptomic and metabolomic profiling of drought-tolerant and susceptible sesame genotypes in response to drought stressImportant metabolites in response to drought stress identified by partial least squares-discriminant analysis (PLS-DA) in DT and DS. Fifty top metabolites according to the VIP (variable importance in projection) score in DS (a) and DT (b) are shown. Metabolites with complex name were indicated by Peak_ID presented in Additional files 5 and 6. Colored boxes indicate the relative concentrations of the corresponding metabolite in each group. c Overlap among drought-responsive metabolites in DT and DS. d Heatmap illustrating the Log2 fold change of selected common drought-responsive metabolites in the leaves of two sesame gonetypes underdrought conditions at two time pointsBack to article page
