Abstract

The invention relates to a reduced genome library building method for millet. The method includes the steps of: 1. utilizing restrictive endonuclease ApeK I for enzyme digestion on the genome DNA of several millet samples respectively to obtain an enzyme-digested product; 2. connecting a bar code joint F and a universal joint R with the enzyme-digested product; 3. mixing the connection products ofthe several millet samples at an equal volume and performing purification to obtain a purified connection product; 4. taking the purified connection product, using a universal primer F and 1 or morebar code primers R for PCR amplification to obtain a PCR product; 5. purifying the PCR product to obtain a target fragment, thus obtaining a sequencing library; and 6. using a high-throughput sequencing platform for sequencing of the sequencing library. The method provided by the invention has the advantages of high detection flux, low cost, good library building stability, and accurate and reliable sequencing result, and at the same time simplifies the genome sequencing and library building steps.

Description

technical field

[0001] The invention relates to genome sequencing technology, in particular to a simplified gene library building method suitable for millet. Background technique

[0002] Reduced-representation sequencing (reduced-representation sequencing) is a high-throughput sequencing method for sequencing part of the genome, mainly including RAD (restriction-site associated DNA), GBS (genotyping-by-sequencing), 2b-RAD (type IIB restriction-site associated DNA) and other technologies. The basic principle is to carry out sequencing on the machine after digesting the sample DNA. Due to the small amount of sequencing data and the ability to evenly distribute across the entire genome, these technologies are being used more and more widely, and have been widely used in the construction of genetic linkage maps after genotyping, population genetic diversity assessment, population evolutionary analysis, etc. However, subject to technical conditions such as low throughput, hig...
