Abstract

The invention discloses a complete sequence of an anthocyanidin reductase gene from Rubus ideaus L. and a preparation method thereof. According to the invention, Rubus ideaus L. is used as a raw material, a method of combined RT-PCR technology and RACE technology is employed, and the full length cDNA of the anthocyanidin reductase gene (RiANR) from Rubus ideaus L. is cloned; the cDNA comprises an open reading frame with a size of 1020 bp and codes a protein composed of 339 amino acids and having a theoretical isoelectric point of 5.81 and a theoretical molecular weight of 36413.8 D, which are identical to the results of prokaryotic expression SDS-PAGE electrophoresis detection. Cloning and expression analysis are carried out on the anthocyanidin reductase RiANR gene from Rubus ideaus L. in the invention, so a base material is provided for further exploration of the regulation and control mechanism of proanthocyanidin from Rubus ideaus L., and important gene resources are provided for acquiring novel crop varieties with high proanthocyanidin content through genetic improvement.

Description

Technical field [0001] The invention relates to the field of gene cloning, in particular to a complete sequence of raspberry anthocyanin reductase gene and a production method. Background technique [0002] Raspberry (Rubus ideaus L.) is a berry of the genus Rubus of the Rosaceae family, commonly known as raspberry, tray, and mountain foam. Because its berry is sweet and mellow, rich in nutrients, and rich in ellagic acid (Ellagic acid), anthocyanin (anthocyanin), proanthocyanidin (proanthocyanidin, PA) and other biologically active substances with strong antioxidant properties, it is given the first The three-generation health-care "golden fruit" has the reputation of being a promising fruit tree variety and medicinal plant (Guo Junzhan et al., 2004; Jiang Guihua et al., 2006). [0003] Procyanidins, also known as condensed tannins, belong to flavonoids and are secondary metabolites of a series of reactions in the phenylalanine metabolic pathway (Deluc et al., 2006). Proanthocya...
