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.

Embodiment 1

[0074] Embodiment 1: Obtaining of SOF1 gene and DNA barcode

[0075] 1. Using the high-coverage proteome technology, pFind and pAnno software were used to conduct a deep coverage study of the proteome of the industrial fermentation fungus Arthrospora adenorivorum TMCC 70007, and its genome was verified for its annotated coding genes. Specifically, in order to discover new protein coding regions, using the Six Frame Translation strategy in systematic proteomics, a six-frame translation database of the genome data of Arthrospora adenophagous TMCC 70007 was obtained, exhaustively enumerating There are 6 coding possibilities of the genome (+1, +2, +3, -1, -2, -3), and the protein sequence is called "six-box translation protein sequence", and the corresponding nucleic acid sequence is called "six-box translation Nucleic acid sequence". Generally speaking, a six-frame translated nucleic acid sequence is the sequence from one terminator to the next, which is also referred to herein ...

Embodiment 2

[0099] Example 2. Identification of bacterial strains using DNA barcodes

[0100] 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 .

[0101] (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 SOF1-F: 5 '-GCCGCACGTCCAATATTTTTC-3'; SOF1-R: 5'-GCTGATCGGGTAGAGCAAGT-3'.

[0102] Figure 8 The position of the primer used to amplify SEQ ID NO.1 in one embodiment of the present invention is shown, the underlined region in the sequence is the region where the primer is located, and the ATG and TAG in bold font are the start and stop sites, The gray background region is the intron r...
