Fig. 4

Avocado mesocarp lipidome during fruit maturation and ripening. (a) PCA analysis of features detected in all mesocarp samples, except the smallest stage (60 g); fruit growing and ripening stage is indicated by color and mesocarp DW is depicted by circle size. (b) Mean values (n = 3) as a function of fruit growth and ripening stage of the two divergent groups of selected features (see Additional file 1: Figure S6) from PC1, blue lines represent features that are characteristic of growing fruit and red lines of ripening fruit. (c) Cloud plot with chromatograms from mature green mesocarp (top) and ripe mesocarp (bottom), dots are placed above the feature elution time and their color and position represents the feature’s m/z. (d) Classification of features characteristic of mesocarp from growing and (e) ripening fruit by Lipid MAPS® Classification [45]; solid bars represent ‘fixed’ assignations and shadowed bars, ‘variable’ assignations
