Project description:Blueberry is one of the most desirable and nutritious fruits. During fruit development, the blueberry’s organoleptic properties and phytonutrient composition are ever-changing [1]. Blueberry fruit development is typically described in five phases: pads, cups, green, pink, and blue (ripe) [2]. The former two phases are referred to as the initial “expansion”. During expansion, young fruit is generally hard, dark green and distinguishable by size [3]. The latter three phases are referred to as maturation. Green fruit are hard and fully rounded green berries; pink berries are partially pigmented; blue (ripe) berries are fully colored and soft. Fruit maturation has attracted considerable research attention, and typically, the characteristics fruit softening, coloring, and sweetening are assessed [4].

Project description:Environmental factors play an important role in anthocyanin biosynthesis, and potassium, an essential nutrient for blueberry growth, can act as an enzyme activator. However, few reports exist on the transcriptional and anthocyanin metabolic changes in blueberries regulated by potassium. In this study, blueberries treated with potassium at different stages were compared for changes in enzyme activity, transcription, and metabolism related to anthocyanin synthesis. The results showed that potassium treatment significantly enhanced the activities of key enzymes F3H, F3'5'H, and UFGT in the anthocyanin synthesis pathway of blueberry fruit. Metabolomic results indicated that the contents of malvidin, petunidin, and delphinidin were higher with potassium fertilization, and potassium treatment promoted the early color change of blueberry fruit. The transcriptome analysis identified 102 glucose metabolism-related genes and 12 differential potassium transport genes potentially involved in potassium-regulated anthocyanin synthesis and accumulation. It was found that thirteen genes relate to anthocyanin synthesis. UFGT, F3H, CHI, HCT, C12RT1, DFR, and F3'5'H were all closely associated with potassium-controlled flavonoid and anthocyanin metabolite synthesis. It provides valuable insights into the molecular mechanisms that regulate the synthesis of anthocyanins in blueberries.
