Embodiment Construction

[0027] The present invention is further described below in conjunction with specific embodiment, but the protection scope of the present invention is not limited to this:

[0028] 1. Obtain the full-length sequence of the kale BoWRKY33 gene:

[0029] The whole-gene amplification primers were designed with NCBI primer design tool, and the CDS sequence of Brassica oleracea in Brassica Database (BRAD, http: / / brassicadb.org) was used as a reference. Take the cDNA of the kale 'Four Seasons thick strip' leaf planted in the cultivation room of Zhejiang University's agricultural life ring as a template (the extraction method of cDNA is a conventional technique, for example, refer to CN 104561025A), design specific primers, use PrimerSTAR high-fidelity enzyme PCR Amplify the BoWRKY33 fragment.

[0030] The primer sequence is: SmaI-BoWRKY33-F:TCTAGACCCGGGATGGCTGCTTCTTCCCTCCT

[0031] BamHI-BoWRKY33-R:AGTGGATCCCGACAAGAACGAATCAAAAAACGA

[0032] PCR amplification reaction system: 2xPrim...

Abstract

The invention relates to the field of biotechnology, in particular to the kale BoWRKY33 gene and its application in resistance to black spot caused by Alternaria brassicicola. Specifically, the present invention discloses a gene BoWRKY33 for improving the resistance of kale to Alternaria brassicae and a protein encoded by the gene, and also discloses a gene overexpression vector 35Spro::BoWRKY33-YFP, a gene silencing VIGS vector BoWRKY33 ‑PTY.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to the kale BoWRKY33 gene and its application in resistance to black spot caused by Alternaria brassicicola. Background technique [0002] Brassica vegetables are the vegetables with the largest cultivation area, the highest total output and the largest consumption in China. The production of Brassica vegetables plays an immeasurably important role in the vegetable supply in Asia and other parts of the world. Alternaria Brassica is a kind of necrotrophic fungus, and the black spot disease caused by it is seriously harmful to Brassica crops. Kale, belonging to Brassica genus, is a special vegetable in China. During its production process, it is easily infected by Alternaria Brassica, which affects its yield and the quality and safety of its products. Excavating Kale against Brassica Chain It is of great biological significance and economic value to analyze the resistance genes of gerani...
