Sweet cherry is an important dominant characteristic fruit, and high-quality cultivation is the goal of the industry. Quality control has become the focus of current research. Recently, the research team of sweet cherry High-quality Cultivation in the College of horticulture, Sichuan Agricultural University used metabonomics and transcriptomics to jointly analyze and found that cornflower 3-rutoside, glucose and malic acid are the main substances that determine fruit quality, and dug out important regulatory genes for fruit quality, such as wrky3, nac71, wrky57, myc2 and tcp21. The regulation network of fruit quality is shown in the figure below:cyp707a, nced and Zep genes affect fruit maturation by regulating endogenous ABA content. Inv, SPS and Sus genes that affect glucose content are regulated by nac71, wrky57 and wrky3. The precursor of cornflower 3-rutoside, which affects the fruit color, is regulated by myc2 by activating the expression of PAL and C4H. Tcp21 is indirectly involved in the synthesis of cornflower 3-rutoside mainly by regulating Chi and F3H. Wrky3, nac71 and wrky57 are directly involved in the synthesis of cornflower 3-rutoside by activating the expression of DFR, ans and 3GT genes. The research results established the main quality control network of sweet cherry, which laid the foundation for the cultivation of high-quality fruit.
