Abstract

The invention discloses a red purple bud tea tree R2R3-MYB gene CsMYB2 and its application, belonging to the field of biological genes. The present invention obtains the nucleotide sequence of the CsMYB2 gene as shown in SED NO ID: 1 by designing the CsMYB2 fragment, the RACE fragment and full-length primers, amplifying and sequencing, and then translating it into an amino acid sequence and analyzing the structure of the gene. From the analysis of the amino acid structure of CsMYB2, CsMYB2 may have the function of regulating the biosynthesis of anthocyanins in tea tree buds and leaves, and then it was confirmed that CsMYB2 has the function of regulating anthocyanins biosynthesis by transforming Arabidopsis. It laid the foundation for the application of CsMYB2 in improving the accumulation of plant pigments.

Description

technical field

[0001] The invention belongs to the field of biological genes, in particular to a red purple bud tea tree R2R3-MYB gene CsMYB2 and its application. Background technique

[0002] Anthocyanidin, also known as anthocyanidin, is one of the most important metabolites in the biosynthetic pathway of flavonoids and is an important water-soluble flavonoid pigment in nature. Anthocyanins in plants are unstable and often combine with sugars to exist in the form of glycosides to form anthocyanins. In addition to glucose, the glycosyl donor can also be replaced by different sugars such as galactose, rhamnose, arabinose and xylose (Panagiotis Arapitsas, 2008). Due to the differences in the site and number of glycosylation of anthocyanins and the differences in the degree of methylation and acylation, various anthocyanins are formed in natural plants and accumulate in the form of glycosides in plant cells. in the vacuole. Anthocyanin belongs to flavonoids, its basic stru...
