摘要:

为进一步探究BvM14-STPK蛋白激酶在甜菜中应答盐胁迫的信号途径,本研究对BvM14-STPK蛋白激酶进行了互作蛋白的鉴定及筛选。使用转基因技术获得转基因烟草,使用亲和纯化串联质谱技术鉴定蛋白复合物,通过搜索烟草蛋白质数据库,获得BvM14-STPK蛋白激酶的候选互作蛋白;使用实验室甜菜M14品系盐胁迫转录组数据,对得到的互作蛋白的编码基因进行盐胁迫下的转录水平分析。结果表明,在烟草数据库中,非盐处理条件下获得3个BvM14-STPK蛋白候选互作蛋白质,盐处理条件下获得6个候选互作蛋白质;经过盐胁迫转录组数据分析,发现有4个互作蛋白编码基因在不同的组织部位、不同的盐浓度条件下应答盐胁迫。为后续进一步在植物体内验证BvM14-STPK蛋白激酶与候选互作蛋白的相互作用及甜菜抗盐机理奠定良好的基础。

Abstract:

To further explore the signal pathway of BvM14-STPK protein kinase in response to salt stress in sugar beet, the interaction proteins of BvM14-STPK protein kinase were identified and screened in this study. Transgenic tobacco was obtained by transgenic technology, and the protein complex was identified by affinity purification tandem mass spectrometry (TAP/MS). The candidate interaction proteins of BvM14-STPK protein kinase were obtained by searching the tobacco protein database, and the RNA-sequencing data of sugar beet M14 was used to analyze the transcription level of the genes which encoded the candidate interaction proteins under salt stress. The results showed that, three BvM14-STPK protein candidate interaction proteins were obtained under non-salt treatment, and six candidate interaction proteins were obtained under salt treatment in the tobacco database. The transcriptome data analysis under salt stress showed that four interaction protein-coding genes responded to salt stress at different tissues and different salt concentrations. It is a positive foundation for further verification of the interaction between BvM14-STPK protein kinase and its candidate interaction proteins in plants and the salt resistance mechanism of sugar beet.
