具体实施方式:
本发明提供的项目实施方案用于说明本发明,但是不局限于本发明的研究范围。如果没有特别指出,本发明实施中的技术手段为本研究领域的常用技术,所用原料为市场所购。
实施例1拟南芥转录因子AT3G46090基因序列的获得以及植物表达载体的构建。
登录拟南芥信息资源数据库网站https://www.arabidopsis.org/servlets/TairObject?type=sequence&id=30046,找到转录因子AT3G46090基因的序列(SEQ IDNo.1),根据AT3G46090基因的CDS设计PCR扩增引物,
AT3G46090-F:5'-ATGGTTGCGAGAAGTGAGGAA-3'
AT3G46090-R:5'-TTAACTCCAAGAAATCGTTCT-3'
培养野生型拟南芥Col-0,取短日照生长3周的拟南芥叶片为材料,TRIzol法提取植物总RNA,经反转录PCR获得cDNA,随后以cDNA为模板扩增目的序列。
提取RNA具体步骤如下:在液氮环境中将拟南芥叶片研磨粉碎,待液氮完全挥发后,将样品分装至装有1mL TRIzol的离心管中快速混匀,室温静置,酚氯仿抽提两次,取上清,而后用等体积异丙醇沉淀20分钟,低温高速离心,弃上清后用乙醇洗沉淀两次,待吹干乙醇后用20μL Rnase-free的去离子水溶解即为提取好的RNA。
反转录PCR方法如下:离心管中依次加入取2μL拟南芥总RNA(1μg)、10μL不含核酸酶的ddH2O、4μL 5*反应缓冲液、1μL Oligo(dT)18引物、2μL dNTP、1μL RNase抑制剂及1μL反转录酶,混合均匀后42℃反应1小时,70℃处理5min终止反应,即为反转录的cDNA。将cDNA稀释后依次加入PCR缓冲液、dNTP、引物、DNA聚合酶和不含核酸酶的ddH2O后用PCR仪进行扩增反应,程序如下,热启动98℃10s,60℃5s,72℃15s,30个循环后,72℃延伸5min。
获得拟南芥转录因子AT3G46090基因的CDS序列:按照PrimeSTAR聚合酶扩增体系和反应程序进行PCR。根据Gateway克隆技术的要求,此过程中包含两轮PCR,第一轮PCR的引物用加部分adaptor attB接头的引物,而第二轮的模板用第一轮的PCR产物,并且引物采用完整的adaptor attB引物。将PCR产物克隆到连接pDONR克隆载体上,经测序鉴定得到与目的基因完全相同的序列。通过LR反应将AT3G46090基因构建到植物表达载体pGWB11(图1)上,获得载体AT3G46090-FLAG::pGWB11(图2),该载体全序列如SEQ ID No.2所示。该载体具有在植物中表达融合蛋白AT3G46090-Linker-FLAG的功能,其中linker为Gateway载体重组位点编码的氨基酸序列YPAFLYKVVDNS,FLAG标签的氨基酸序列为DYKDDDDK;AT3G46090为拟南芥转录因子AT3G46090编码的氨基酸序列(SEQ ID No.3)。
实施例2转基因拟南芥植株的获得
首先植物培养至开花期,随后用农杆菌蘸花法进行转化,收取种子后进行转基因植物的筛选。
植物培养的方法:
取足量拟南芥种子装入离心管中进行表面消毒。首先用75%乙醇表面消毒30s,无菌水漂洗一次,接着用1%NaClO表面消毒5-8min后,用无菌水漂洗三次;完成表面消毒后,将处理好的种子播种于1/2MS培养基平板上。将点好的平板用parafilm膜封口,并放于4℃黑暗处理。2-4天后将平板放置于植物光照培养箱(光照周期为12h光照/12h黑暗)。待种子萌发后8天,将拟南芥幼苗转载至营养土,同样光照条件下进行生长,定期浇水。待上述培养的拟南芥生长至6-8周时,剪去成熟的果荚,用以准备转化。
农杆菌蘸花法转化:
将植物表达载体AT3G46090-FLAG::pGWB11转化农杆菌GV3101(pMD19),并筛选阳性克隆;将阳性克隆用YEB于28℃进行培养,随后以1:100比例接种至200mL YEB液体培养基扩大培养,室温离心收集菌体,并将之重悬于新配的5%蔗糖溶液;在蘸花转化前,在菌悬液中加入终浓度为0.02%的Silwet L-77,混匀后将拟南芥花序浸泡于菌液中30s,将植物平放于黑暗高湿环境中16-24h后,正常培养至种子成熟,收取种子以备筛选。
转基因植物的筛选:
将收取的拟南芥种子经表面消毒处理后(处理方法同上),平铺于含有50mg/L卡那霉素抗性的1/2MS平板,经4℃黑暗处理两天后,置于植物光照培养箱培养;7-10天后可见明显的转化子表型。成功的转化子正常生长,而未成功转化的植物黄化并且不再生长。将获得的转化子转移至营养土中进一步生长,按期浇水管理。3-4周后,将拟南芥叶片提取基因组DNA进行进一步鉴定。
实施例3转基因拟南芥的验证
以转基因植物的叶片为材料提取基因组DNA,并进行PCR验证,确认AT3G46090-flag DNA片段插入拟南芥基因组。
基因组DNA的提取:
取50mg待检测的正常生长的拟南芥叶片研磨后加入400μL植物基因组DNA提取液(200mM Tris-Cl pH7.4,250mM NaCl,25mM EDTA,1%SDS),涡旋混匀后高速离心5min,吸取上清并加入等体积异丙醇,室温沉淀30min,高速离心5min后弃上清,用70%乙醇清洗沉淀两次,将沉淀溶解于20μL无核酸酶的ddH2O。
利用pGWB11载体的特异引物进行PCR扩增:
以上述提取的基因组DNA为模板进行PCR,体系包括5*缓冲液4μL、上游引物及下游引物各1μL、10mM dNTP 0.5μL、基因组DNA 1μL、Taq聚合酶0.5μL和无核酸酶的ddH2O12μL。PCR程序为热启动95℃30s,58℃30s,72℃30s,30个循环后,72℃延伸5min,结束反应。将PCR产物进行琼脂糖凝胶电泳检测,转化子基因组DNA中可以扩增得到目标条带,而未转化的不能得到目标条带。
pGWB11特异引物为:
pGWB11-F:5'-gggactctagagttatca-3'
pGWB11-R:5'-gggaaattcgagctctaagc-3'
实施例4转基因植物的WB检测
取生长4周的植物叶片1g,用液氮速冻,并迅速将植物叶片研磨粉碎,在蛋白提取缓冲液中混匀,13000g离心15分钟,即为蛋白粗提液。配置12%分离胶、4%浓缩胶的SDS-PAGE。取10ul蛋白粗提液进行电泳检测。首先80V的低电压电泳30分钟,使蛋白样品跑至同一条线,然后再120V的高电压下电泳90分钟左右,直至溴酚蓝条带跑到底端,停止电泳。电泳后利用湿转法转膜约60分钟,接着用丽春红染液进行染色观察,确定转膜质量;然后将膜置于含有5%脱脂奶粉PBST溶液中封闭60分钟,接着用一抗FLAG单抗隆抗体(sigma,CAT号为:F2555)孵育2小时,完成后用PBST洗涤3次,每次10分钟;随后用5%的PBST脱脂奶粉封闭30分钟,用二抗山羊抗兔IgG(H&L,HRP,货号ab6721)标记2小时,最后用PBST洗涤3次,每次5分钟,在膜上加入底物,黑暗条件下进行曝光。鉴定结果表明在野生型Col-0中没有发现FLAG出现的蛋白条带,但是在转基因植物中存在可以被FLAG抗体识别且大小符合预测的蛋白条带。
实施例5转基因拟南芥植株的抗病表型分析
本发明中施用的病原菌为丁香假单胞菌番茄亚种(Pst DC3000)。该病原菌可侵染包括番茄、拟南芥等在内的植物。
首先将病原细菌Pst DC3000菌种涂布于含有20mg/mL利福平的LB培养基,28℃黑暗培养,待生长出单克隆后挑取单克隆于2mL加有利福平的LB培养基过夜培养。将过夜培养的菌液离心收集菌体,并用10mM MgCl2洗菌体两次,最后用10mM MgCl2重悬菌体并调节至合适浓度。将菌悬液分别注射野生型及转基因拟南芥叶片,并以注射10mM MgCl2的为对照,3天后观察表型,结果如图3所示,野生型拟南芥叶片(左)病原菌大量增殖,呈现黄色病斑,而转基因拟南芥的叶片(右)几乎无表征或者呈现坏死,病原菌的增殖受到抑制。
以上提供的实施例是将拟南芥AT3G46090基因的CDS序列通过Gateway技术构建到带有FLAG蛋白标签的上游,并成功转化拟南芥,该基因的表达可影响拟南芥抗病表型。
虽然,上文中已经用一般性说明及具体实施方案对本发明做了详尽描述,但在本发明基础上,可以对之稍作修改或改进,这对本领域技术人员是显而易见的。同样的,将拟南芥AT3G46090的CDS序列构建到其他蛋白标签的上游或下游也可以达到相应效果。因此,在不偏离本发明的精神的基础上所做的修改或改进,均属于本发明要求保护的范围。。
