摘要
Abstract
In higher plants, there are many WRKY transcription factors in WRKY family. They are widely involved in biotic stress; abiotic stress; growth; development and metabolism regulation. Cloning WRKY6 from potato by homology cloning. Analysis show that the WRKY6 belongs to the third group of WRKY family members, zinc-finger structure is C-X7-C-X23-H-X-C. Phylogeny results show WRKY6 is the most closest to AtWRKY70 with 58% similarity, By SDS--PAGE analysis, the best expression conditions of WRKY6 are that host bacteria-Escherichia coli (DE3) is growing for 8 hours under 18℃ adding 0. 2 mmol/L IPTG (Isopropy1βD-thiogalactoside), purified protein of high specificity is obtained. This research lay. a solid foundation to further study the foundation of WRKY6.关键词
