    • 摘要: MYB102转录因子在番茄响应低温胁迫中起着重要作用,为了进一步探究番茄转录因子MYB102的分子作用机理,筛选其蛋白,以“Bolgogragsky”为材料,从番茄的根、茎、叶、花、果以及萼片组织中提取总RNA,以其为模板合成双链cDNA,纯化后与载体pGADT7-Rec共转化入酵母Y187感受态细胞中构建酵母双杂交cDNA文库。经测定,文库容量为2.31×10^(7) CFU,cDNA文库的转化效率为7.02×10^(6) CFU/μg,文库滴度为2.5×10^(8) CFU/mL,重组率为97%,插入的cDNA片段长度主要分布在250~2000 bp。结果表明,构建的番茄cDNA文库符合酵母双杂交文库要求,可用于筛选MYB102的互作蛋白。

Total RNA was extracted from flower pedicel AZ which is in different abscission points. Using SMART technology, cDNA was synthesized and purified by CHROMASPINTM+TE-400 column. Finally the purified PCR product was co-transformed with plasmid pGADT7-Rec into competent yeast Y187. The transformed yeast cells grew on the SD-Leu medium plates. All the growing clones were harvested and then established the cDNA library. The cDNA library transformation efficiency was 5.6×106cfu?μg-1. Harvested library had 2.4×107cfu independent clones. The library titer was 3.2×108cfu?mL-1, average length of the insertions was more than 1000 bp and recombination rate was 100%.Twenty single clone sequences of the cDNA library were blasted by NCBI database, containing nineteen sequences with known functions and one unkown sequence. The proteins coding by the sequences with known functions are divided into four parts including enzyme, transcription factor, carrier and stress-responding protein. These proteins are involved in many biological processes including protein phosphorylation, water transportation, oxidation-reduction process, etc. Seven sequences involves in abscission. The results indicate that our library can be used to screen the interaction proteins for participating in tomato pedicel abscission.

    • 摘要: To understand how Zea mays L.centrin(ZmCEN)function,we employed the technique of yeast two hybrid system (Y2HS) to investigate the interaction between interacting-proteins and ZmCEN.In this study,using maize inbred line Zheng 58 seedlings as materials,we isolated the total RNA and synthesized the double-strand cDNAs by SMART technology.According to the CDS sequence of the ZmCEN gene,we designed the primers to construct recombinant bait vector (pGBKT7-ZmCEN) and transform yeast strain Y2HGold for screening the toxicity and self-activation ability of bait vectors.We screened the prey proteins interaction with ZmCEN.Interacting proteins NAC67 and TON1b were verified the interaction by β-galactosidase assay in vitro.The BiFC semi-molecule vectors of ZmCEN-pSPYNE and TON1b-pSPYCE were constructed to further confirm the interaction in Arabidopsis cells.Gene and Ontology (GO) enrichment analysis were performed on the screened proteins using Uniprot and KEGG online sites.The results showed that the unamplified cDNA library was consisted of 2.56 × 107 CFU independent clones,and the titer of library was 5.36 × 108 CFU/mL which met the requirements of library construction.The cDNA library was screened by bait vector after testing no toxicity and no self-activation,and 28 proteins were interacted with ZmCEN by sequencing and Blast alignment analysis.GO enrichment analysis of these proteins showed that there were 21 terms in the biological process.The ZmCEN and TON1b proteins were further verified interaction in Arabidopsis cell by BiFC technology.A high-quality cDNA library was constructed and 28 proteins were interacted with ZmCEN,which could be used to further investigate the interaction mechanisms between them.%为阐明玉米中心蛋白(ZmCEN)的生物学功能,采用酵母双杂交技术对其互作蛋白进行研究.提取玉米(Zea mays L.)自交系‘郑58’幼苗的总RNA,利用SMART技术反转录合成ds cDNA,构建以pGBKT7为载体的酵母双杂交cDNA文库;依据ZmCEN基因的CDS序列设计引物,构建重组诱饵载体(pGBKT7 ZmCEN)转化酵母菌株Y2 HGold,检测诱饵载体的毒性与自激活能力后,筛选与玉米中心蛋白(ZmCEN)互作的猎物蛋白.将筛选的互作蛋白NAC67和TONNEAU1b (TON1b)再次验证相互作用,并选取互作蛋白TON1b,采用BiFC实验分别构建ZmCEN-pSPYNE和TON1b-pSPYCE BiFC半分子重组载体,转化拟南芥原生质体,进一步验证它们在细胞内的互作;并利用Uniprot和KEGG在线网站对互作蛋白进行gene ontology(GO)注释分析.结果表明:玉米全株幼苗的cDNA文库库容量达到2.56×107 CFU,文库滴度5.36×108 CFU/mL,符合建库要求.经检测诱饵载体无毒性也无自激活功能,所筛选的cDNA文库经测序和Blast比对分析以及共转验证,最终得到28个与诱饵蛋白ZmCEN互作的蛋白质.GO注释显示互作蛋白参与的生物过程有21种.BiFC结果显示,蛋白TON1b与ZmCEN在拟南芥原生质体细胞内互作而形成互补,从而产生黄色荧光,进一步证实了两者存在互作关系.酵母双杂交系统cDNA文库的成功构建与筛选,为进一步研究玉米ZmCEN及其与互作蛋白的作用机制奠定了基础.

    • 摘要: ZmSCL1 is a member of GRAS gene family. Although highly expressed in maize seeds in the key period for the filling period of maize,especially in the endosperm,the molecular function of ZmSCL1 for maize seeds development remains unclear. Therefore,to screen interaction factors for ZmSCL1,yeast two-hybrid cDNA libraries of maize inbred line(B73)developing seeds(12 and 20 days after pollination)were constructed in yeast strain AH109 using homologous recombination-mediated SMART technology. The qualities of the cDNA libraries were evaluated as the followings :the titers were 1.10×105 CFU/mL,the capacity of cDNA library was 1.32×106,the recombinant rate was 81.90%,and the protein length encoded by the inserted cDNA ranged from 133 aa to 500 aa. Finally,109 clones were obtained for sequencing. GO enrichment analysis showed that,ZmSCL1 may be involved in the regulation of starch and nutrition accumulation.%ZmSCL1属于GRAS家族基因,在玉米籽粒,尤其是胚乳中高表达,而这个时期是玉米灌浆的关键时期,鉴于ZmSCL1的分子功能以及其与玉米籽粒发育的关系尚不明确.利用SMART同源重组交换技术,在酵母菌株AH109中构建了玉米自交系B73授粉后不同时期籽粒的cDNA文库,利用此文库筛选了ZmSCL1的互作因子.文库质量评定结果显示:cDNA文库的滴度为1.10×105 CFU/mL,文库的库容量为1.32×106,文库的重组率为81.90%,插入片段所编码的蛋白质长度在133-500个氨基酸之间.最终,获得了190个阳性克隆.对这些克隆进行测序,利用GO注释对所筛选的互作因子进行初步分类,并进行功能富集分析.结果显示ZmSCL1可能参与结合、催化以及营养储备相关生物过程的调控.
