Fig. 2From: Transcriptomic and metabolomic profiling of flavonoid biosynthesis provides novel insights into petals coloration in Asian cotton (Gossypium arboreum L.)Preliminary analysis of metabolomics data. Comparison of metabolite composition and content in petals. A Principal component analysis (PCA) of the metabolite quantification in petals of three colors (W_Flo, Y_Flo, P_Flo). B Cluster analysis of all metabolites from samples of W_Flo, Y_Flo and P_Flo. In the heat map, different colors represent the degree of accumulation of each metabolite, with red to blue indicating high to low. C Detailed classification of flavonoid metabolitesBack to article page
