专利名称:棉花Na的制作方法
技术领域:
本发明涉及棉花中Na+/H+反向转运蛋白基因GhNHX1的克隆、重组及耐盐性功能的分析和应用,属于分子生物学和生物技术领域。
由于Na+/H+反向转运蛋白基因在耐盐过程中所起的作用,本发明人从棉花中分离编码液泡型Na+/H+反向转运蛋白的基因。根据其它植物中发表的Na+/H+反向转运蛋白的氨基酸序列,设计引物,利用反转录-聚合酶链式反应,从棉花中分离出编码液泡型Na+/H+反向转运蛋白的基因。将该基因转入盐敏感酵母突变体,能在一定程度上恢复其抗盐能力。进一步构建正义表达载体,转化烟草,转基因植株具有较高的耐盐性,耐盐性可达200mmolL-1。该基因可用于植物的遗传转化,提高植物的耐盐能力。
本发明首次从棉花中分离出编码液泡型Na+/H+反向转运蛋白的全长cDNA,连接到表达载体上,利用农杆菌侵染法转化烟草,获得的转基因植株耐盐性高达200mmolL-1。
从棉花叶片中提取总RNA,然后将2微克总RNA反转录成cDNA。根据其它植物中的Na+/H+反向转运蛋白中保守的氨基酸序列,设计一对兼并引物正向引物5′-CC(GATC)CC(GATC)AT(TAC)AT(TAC)TT(TC)AA(TC)GC-3′反向引物5′-GT(GATC)AC(GATC)TT(AG)TGCCA(GATC)GT(AG)TA-3′进行常规聚合酶链式反应(PCR),取2μl PCR产物连接到pGEM-T easy载体上,转化DH5α感受态细胞,涂平板,筛选阳性克隆,挑白斑摇菌,提取质粒,并进行酶切鉴定,之后进行序列测定。然后进行3′和5′末端快速扩增获得全长cDNA。具体的PCR试剂与条件为10×反应缓冲液5μl25mM MgCl24μl10mM脱氧核苷酸混合物(dNTP)1μl正向引物(10μM) 2μl反向引物(10μM) 2μl模板cDNA 1μlTaq DNA聚合酶 0.5μl总体积50μlPCR反应条件为94℃ 5分钟,然后进入下列循环94℃ 1分钟,55℃ 1分钟,72℃ 1分钟,共30个循环,最后72(C延伸5分钟。
结果扩增到一个614bp的DNA片段。取2μl PCR产物连接到pGEM-T easy载体(Promega公司产品),转化DH5α细胞(常用载体宿主细胞),平板过夜培养。挑取白色菌斑,提取质粒DNA,用于序列测定。
经过3′和5′末端快速扩增获得全长的cDNA为2485bp,包括起始密码子前的上游序列和多聚A尾巴。开放阅读框部分为1629bp,由此推得具543个氨基酸的一段序列,将此氨基酸序列在国际基因库中进行比较,表明与已发表的野滨藜、水稻和拟南芥的Na+/H+反向转运蛋白的氨基酸同源性分别为77.30%、72.74%和76.61%,表明经过上述克隆步骤得到了编码Na+/H+反向转运蛋白的基因。该基因序列如下序列表(1)SEQ ID NO 1的信息(a)序列特征*长度2485碱基对*类型核酸*链型双链*拓扑结构线性(b)分子类型cDNA(c)假设否(d)反义否(e)最初来源棉花(f)序列描述SEQ IN N0.1ACGCGGGGCAACACAGTCTTGATTTTGATCGTTTTTCGCTCCCATCGAAAGCGAAGATTT 60TAAGCTGAAAAAAGAAGAGAGGAAAATTGTGGCAATTTGTTGGTGAGAAAGTCGAAGATT 120CACGTGGGTAAGCTCCATAAACAGTGAAACATTGGATTTTCTTTTTTGTTTTTGTTTTCT 180CAAGCTCTCTCTTCGAATTTACTCGTCTCTTTGAAACTGTCCGTTTTTTTTTGGTTCAAT 240AAAATCGCAAATTATTTGCTAATTTAGAGAAGAAAATTGAACGGAGCTGAAACAAGGATG 300ATTTGTTGCTGCATGATGTTGATTCTCCAAAACGATTCGAGTGCTTAAGGATTTTAAGAT 360TAGAAAGTTCTTGAAATGGACAGTTCAGAGGCATAAAAATTTTCGAAGATTTACATTGTT 420GAAGGAGAGCTTAAATCTGAAGCCTTGGACTACAACTGTTTCAGTTAGAAGGAATTGGTG 480TTTAATAAAATTTGATTTAAAAAGAGGTCAATATGGTGGCTCCGCAGTTAGCTGCTGTCT 540TTACTAAGTTGCAGACACTATCTACTTCAGACCATGCGTCTGTGGTCTCCATGAACATAT 600TTGTAGCGCTTCTTTGTGCTTGCATTGTGATTGGTCATCTTTTGGAGGAGAATAGATGGA 660TGAACGAATCAATTACTGCCCTTATCATTGGTGTTTTTACTGGGGTCATTATTTTGTTGA 720CAAGTGGGGGTAAAAGCTCTCATCTTTTAGTCTTCAGTGAAGATCTGTTCTTTATCTATC 780TTCTGCCCCCTATTATATTCAATGCTGGGTTTCAGGTGAAAAAGAAGCAATTTTTCCGTA 840ACTTTATCACCATCATGCTGTTTGGGGCTGTTGGTACACTAATATCTTGTACAATTATCT 900CTTTAGGTGTAATTAACTTCTTCAAGGAAATGGACATTGGCTCCTTAGACATTGGAGATT 960TTCTAGCAATTGGTGCAATATTTGCTGCGACAGATTCTGTTTGCACACTGCAGGTGCTTA 1020ATCAGGATGAGACTCCATTACTCTACAGTTTGGTTTTCGGAGAGGGTGTTGTAAATGATG 1080CAACATCTGTGGTGCTTTTCAATGCAATCCAGAGTTTTGACCTCGTTAATACCAGTCCTA 1140GAATTCTTCTGGAGTTTATTGGCAGCTTTTTGTATTTATTTTTAGCAAGCACTATGCTGG 1200GAGTGATTGTTGGGTTGGTTAGTGCTTACATCATCAAAAAGTTGTACTTTGGAAGGCACT 1260CAACAGATCGTGAATTTGCTCTTATGATGCTTATGGCATACCTTTCGTATATCATGGCTG 1320AACTGTTCTATTTGAGTGGCATTCTTACAGTATTCTTTTGTGGGATTGTGATGTCACATT 1380ATACCTGGCACAATGTAACTGAGAGTTCAAGAGTAACTACAAAGCATGCCTTTGCTACCT 1440TGTCATTTGTTGCTGAGACTTTTCTCTTTCTTTATGTCGGGATGGATGCTTTGGACATGG 1500AGAAGTGGAGATTTGTCAGTGATAGCCCTGGAACGTCAGTTGCTGTTAGTGCTGTGCTGA 1560TGGGTCTTGTTATGGTTGGAAGAGCGGCTTTTGTGTTTCCCCTGTCATTTTTATCCAACT 1620TGGCAAAGAAATCAACTAGTGAGAAAATCAGCTTCAGGGAACAAATTATAATATGGTGGG 1680CTGGGCTCATGAGAGGCGCTGTATCTATGGCACTTGCATATAATCAGTTTACAAGGGGGG 1740GCCATACTCAGTTGCGAGGAAATGCAATTATGATTACAAGCACCATAACCATTGTTCTAT 1800

转化烟草,在含卡那霉素的LB固体培养基上筛选,将筛选出的抗性苗在100mmolL-1、200mmolL-1和30mmolL-1氯化钠的培养基上培养。结果表明,与野生型相比,转基因植株仍能正常生长,具较高的耐盐能力。
转化酵母盐敏感突变株,在选择培养基上筛选转化子,将筛选出的阳性转化子在喊含1600mM氯化钠的选择培养基上培养。结果表明GhNHX1对酵母盐敏感突变株有补偿作用,转6hNHX1的酵母盐敏感突变株的耐盐能力大大增强。
根据上述技术,从棉花中分离出编码液泡型Na+/H+反向转运蛋白的基因GhNHX1,该基因过量表达能导致转基因烟草具较高的耐盐性。让该基因在棉花中表达,将会提高棉花的耐盐性;如果与特异启动子连接,对其表达进行时空和胁迫诱导进行调控,将更具有针对性,具有非常重要的经济效益和社会效益.
