(A) PCA analysis of metabolites extracted from yellow- and white-fleshed triploid loquat fruits. An equal mixture of fruit samples was used for quality control. (B) Categorization of the 489 metabolites detected in the chestnut samples. (C) Cluster analysis of the metabolites extracted from yellow- and white-fleshed triploid loquat fruits at the GF, CT and fruit ripening FR stages. To enhance clarity of data presentation, the heatmap displays the Z-score from the processed data. Downregulated and upregulated differentially accumulated metabolites are represented in blue and yellow, respectively.
