Problems solved by technology

In recent years, due to the increasing market demand, many small-scale manufacturers lack systematic and in-depth research on Pu-erh tea, and wantonly abuse many other people's patents for profit. A series of methods, such as Pu’er tea processing and production, have greatly damaged the economic interests of some Pu’er tea production enterprises with relevant patents.

Embodiment 1

[0072]Embodiment 1: Obtaining of MRPS9 gene and DNA barcode

[0073] The proteome and genome analysis methods and mass spectrometry methods used in this example are all known methods in the art, so the specific operation process will not be repeated.

[0074] 1. Using high-coverage proteome technology, pFind and pAnno software were used to conduct high-coverage proteomics research on the industrial fermentation fungus Arthrosporium adenitivorus TMCC 70007, and its genome was verified for its annotated coding genes. Specifically, in order to discover new protein coding regions, the six-frame translation database of Arthrospora adenophagous TMCC 70007 genome data was obtained by using the six-frame translation (SixFrame Translation) strategy in systematic proteomics, exhaustively enumerating the genome 6 coding possibilities (+1, +2, +3, -1, -2, -3), and the protein sequence is called "six-frame translated protein sequence", and the corresponding nucleic acid sequence is called ...

Embodiment 2

[0093] Example 2. Identification of bacterial strains using DNA barcodes

[0094] According to the amplification result of the sample to be tested and the sequence homology with Arthrospora adenophagous TMCC 70007 strain SEQ ID NO.1, it is determined whether the sample to be tested is the industrially applied strain of Arthrospora adenorivorum TMCC 70007 .

[0095] (1) Based on SEQ ID NO.1, use the NCBI primer design tool to design PCR primers at both ends of the gene. The amplified product must include the start and end sites of the gene, and the sequences of the forward and reverse primers are respectively MRPS9-F: 5 '-ACTCGAAAACCCTATACACCGA-3'; MRPS9-R: 5'-CTTGCACTTGTTTAGTGCCCA-3'. For primer locations see Figure 6 . The amplified sequence is SEQ ID NO.7.

Abstract

The invention belongs to the field of identification of species and strains, and in particular relates to a DNA barcode, primers, kit, method and application for identifying Arthrospora adenovorans strains. The DNA barcode can accurately identify the Pu-erh tea fermentation strain Arthrospora adenorivorum TMCC 70007, and can quickly and accurately identify the strain from confusing strains or other strains within the same species.

Description

technical field [0001] The invention belongs to the field of species and bacterial strain identification, and specifically relates to DNA barcodes, primers, kits, methods and applications. Background technique [0002] Pu-erh tea is a post-fermented tea with the geographical indication of Yunnan. It uses large-leaf sun-dried green tea as raw material and is made through a series of processes. The traditional production process of Pu'er tea is as follows: the picked fresh tea leaves are rolled, sun-dried, impurity-removed, tide-watered, heaped, dried, sieved, pressed and molded, and packaged for delivery. In the production of Pu-erh tea, the heaping fermentation process is the main factor to form the quality of Pu-erh tea. During this process, the internal components of the tea such as tea polyphenols, caffeine and some polysaccharides have undergone tremendous changes, making Pu-erh tea The special flavor, taste, quality and various health benefits of tea. [0003] In the ...
