The CSN5B of Arabidopsis thaliana was cloned by RT-PCR technology and constructed into the prokaryotic expression vector pET-32a (+), which was introduced into E.coli BL21 host bacteria. Isopropylβ-D-1-thiogalactopyranoside (IPTG) was used to induce expression, and the cultural temperature and time was optimized. The sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was employed to detect the induced recombination protein, and the protein purification was conducted. It was shown that the recombinant CSN5B introduced into E. coli could be induced to express, and the induction was relatively effective in the presence of 1mmol/L of IPTG at 30℃, 4h induction effect is better. The molecular weight of the induced recombinant protein was basically consistent with the theoretical molecular weight. This study provided a theoretical basis for in-depth further exploration of the functions of this gene in the future.","PeriodicalId":365098,"journal":{"name":"Molecular Soil Biology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128281047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a large volume of data, and complicated calculation process, the conventional low efficiency calculations delay the study. To empower researchers to quickly tabulate, compute, analyze and present data, we introduced A Biolog EcoPlate data statistics and analyses system (A-BEP-DSAS). It is implemented with Biolog EcoPlate data tested by an ELISA microplate reader (Molecular Devices Versamax). The data input-output process and visual calculation flow are performed using Excel table linked with built-in VBA programming language. We tested A-BEP-DSAS by data from a soil sample, and rapidly and accurately obtained the average well color development (AWCD) data, carbon source utilization, six common diversity indices and other calculation results. A-BEP-DSAS is an automated program based on Microsoft Excel VBA, with the advantages of easy operation, rapid analysis, process visualization, and also allows the user to choose the data source and optimum time for analysis.","PeriodicalId":365098,"journal":{"name":"Molecular Soil Biology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129386527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
