The total RNA of fusariumoxysporum was extracted by the method of Trizol extraction from fusariumoxysporum induced by DHEA for 48 h, and the CYP gene of fusariumoxysporum was amplified by PCR and sequenced. The bioinformatics were analyzed.Results: A full-length cDNA fragment of 3 459 bp was successfully amplified. After sequencing, the amino acid sequence of the CYP6003A1 gene was screened by BLAST on NCBI. The results showed that the first 10 genes were similar to CYP6003A1, among them, three were CYP gene, and the others were genes related to CYP gene. The result of bioinformatics analysis showed that the gene fragment encoded 691 amino acids polypeptide.Conclusion: CYP6003A1 gene has been successfully cloned from fusariumoxysporum and analyzed by bioinformatics %K 7α %K 15α-二羟基DHEA %K 细胞色素P450氧化酶 %K 尖孢镰刀菌 %K 生物信息学< %K br> %K 7α %K 15α-diOH-DHEA %K cytochrome P450 oxidase %K fusariumoxysporum %K bioinformatics %U http://jms.zzu.edu.cn/oa/darticle.aspx?type=view&id=201801009
