Embodiment 1

[0027] The silkworm zinc finger protein gene (gene number BG IBMGA014418-TA) was obtained from silkDB silkworm database, and the Nistari glutamic acid synthase gene sequence was obtained after designing primers to verify the gene sequence. Use the online software CRISPRdirect to design a 20bp sgRNA core sequence, screen out three target sites and synthesize the sequence cccAGATGCCTGACCCTAAGACT, cctGACCCTAAGACTTACAAACA or cctAAGAACGATCTACCAGATGA, respectively add the gaaattaatacgactcactata T7 promoter sequence in front, and the fragment gttttagagctagaaatagc complementary to crRNA / tracrRNA, artificially synthesized to 62bp The front primer, and the back primer crRNA / tracrRNA go through the PCR program to obtain the complete sgRNA sequence, see figure 1 .

[0028] The reagents used are listed in Table 1. The PCR reaction conditions are shown in Table 2.

Abstract

The invention relates to an application of CRISPR/Cas 9 technology in obtaining of bombyx zinc finger protein gene mutation, and belongs to the technical field of bombyx breeding and gene engineering. In the invention, the CRISPR/Cas 9 gene editing technology is applied to obtain bombyx zinc finger protein gene mutation, a set of method for performing gene edition on zinc finger protein and exploring the gene function is realized, and thus a set of effective method for the batch research and transcription factors in future is provided.

Description

technical field [0001] The invention relates to the application of CRISPR / Cas9 technology in obtaining a mutant of the silkworm zinc finger protein gene, and belongs to the technical field of silkworm breeding and genetic engineering. Background technique [0002] The silkworm (Bombyx mori), a holometabolous Lepidoptera insect, is one of the most economically important insects at present. The invention of sericulture and silk reeling is an outstanding contribution made by the Chinese people to world civilization. Transcription factors are very important genes in silkworms. Many traits of silkworms are regulated by transcription factor family genes. Studying the functions of various transcription factors is of great significance for silkworm breeding and silk improvement and as a bioreactor for expressing foreign proteins. [0003] The rapid development of modern biotechnology, including transgenic technology and sequencing technology, has brought new development opportuniti...
