摘  要:
基于香鳞毛蕨转录组数据克隆香鳞毛蕨MYC类转录因子MYC2的基因序列,获得其全长,并命名为DfMYC2,NCBI基因登录号为MK193871,对其蛋白序列进行生物信息学分析、不同部位荧光定量分析及0.4 mmol/L茉莉酸甲酯(MeJA)处理下的表达分析.结果显示:DfMYC2基因全长为3 130 bp,开放阅读框(ORF)的长度为2 496 bp,编码831个氨基酸,相对分子质量为261 041.86;用0.4 mmol/L MeJA溶液喷洒香鳞毛蕨植株叶片,在处理后0、2、4、6、8、12、24、36 h时取样,实时荧光定量PCR检测结果显示,DfMYC2在处理后4 h时表达量最高.

摘  要:
Based on the transcriptome data of Dryopteris fragrans,the gene sequence of MYC2 transcription factor MYC2 was cloned and named as DfMYC2.The gene accession number was MK193871.Bioinformatics analysis of the protein sequence,fluorescence quantitative analysis of different parts and expression analysis of 0.4 mmol/L methyl jasmonate(MeJA) were performed.The results showed that the DfMYC2 gene was 3 130 bp in full length and the open reading frame(ORF) was 2 496 bp in length,encoding 831 amino acids with a relative molecular weight of 261 041.86.The leaves of D.fragrans were sprayed with 0.4 mmol/L MeJA solution,and samples were taken at 0 h,2 h,4 h,6 h,8 h,12 h,24 h and 36 h after treatment.The results of real-time quantitative PCR showed that DfMYC2 had the highest expression at 4 h after treatment.It will provide the foundation for further studying the biological function of DfMYC2 gene in D.fragrans.
