Transcriptomic Analysis of Anthocyanin and Carotenoid Biosynthesis in Red and Yellow Fruits of Sweet Cherry (Prunus avium L.) during Ripening

The diversity of fruit color in sweet cherry (Prunus avium L.) has been attributed to the presence either anthocyanin or carotenoid. We profiled and carotenoid metabolites investigate different pigments underlying regulatory mechanisms differential expression genes (DEGs) between red yellow fruits cherry. two cultivars, ‘Jiangnanhong’(JNH, fruits) ‘Chaoyang’(CY, establish their by LC-MS/MS transcriptome analysis RNA-seq test difference gene metabolic substances varieties. Cyanidin-3-O-rutinoside was most pigment content which significantly higher than one during whole ripening stage (stage 3 4). total types close, but shown be more stable after harvest. Based on data, heatmap selected structural DEGs showed that all expressed levels fruits. Two unigenes encoding chalcone synthase (CHS) UDP glucose-flavonoid 3-O-glucosyltransferase (UFGT) were 1134.58 1151.24 times at 4, respectively. Correlation JNH negatively correlated with those CY; contrast, there some strong correlations observed cultivars genes. Thus, coloration mainly anthocyanin-related
