摘要： Blueberry is one of the richest phenolic sources, providing health benefits. To study blueberry phenolic biosynthesis, we investigated phenolics and proteomics at three typical fruit maturation phases. Multiple isoforms of enzymes and multiple members of transcription factors involved in phenolic biosynthesis were divergent and differently regulated. Regulation of some proteins resulted in change of phenolic content. During fruit maturation, down-regulation of VcOMT (CUFF.177.1) and VcLAR2 (CUFF.16780.1) was associated with decreases of ferulic acid and catechin, respectively; Up-regulation of VcFLS (CUFF.41155.1), and VcF3'5'H (CUFF.51711.1) and VcF3'5'H (gene.g10884.t1.1) likely drove increases of their products (quercetin and myricetin); Up-regulation of VcUFGALT (CUFF.20951.1) and VcUFGT73 (4333_g.1) and down-regulation of VcU5GT (CUFF.51258.1) were correlated to accumulation of anthocyanins with 3-glucoside/galactoside. Additionally, four TFs, VcAPRR2 (CUFF.24826.1), VcbHLH3 (CUFF.37765.1), VcWD (CUFF.28282.2) and VcWD (CUFF.28273.1) were probably related to regulation of anthocyanin biosynthesis. These proteins were potential targets for genetic improvement in a breeding program.
