稻纵卷叶螟钙粘蛋白Cry毒素结合区编码基因及其编码蛋白与应用
技术领域
本发明属于生物基因工程领域,特别是稻纵卷叶螟钙粘蛋白cadherin毒素结合区编码基因与应用。
背景技术
稻纵卷叶螟Cnaphalocrocis medinalis是中国和其他亚洲国家在水稻上的主要害虫(Khan et al.,1988;Riley et al.,1995;Yang et al.,2018a)。稻纵卷叶螟幼虫通过折叠水稻叶片使其叶片脱叶来取食,造成水稻产量严重损失(Padmavathi et al.,2013;Senthil-Nathan,2019)。目前,对稻纵卷叶螟的防治主要使用化学杀虫剂,由于环境影响、害虫抗药性等问题,不建议对害虫使用化学农药(Li et al.,2016;Xiao and Wu,2019)。生物农药由微生物或天然产物制备而来,且对环境无害,是化学农药有效的替代品(Chandleret al.,2011)。来源于苏云金芽孢杆菌(Bacillus thuringiensis,Bt)的Bt毒素蛋白是目前最常用的生物农药,在孢子形成阶段会产生杀虫晶体蛋白(Cry毒素),这些晶体蛋白对特定昆虫具有高活性,对脊椎动物或环境无害(Bravo et al.,2011; Mendelsohn et al.,2003;Sanahuja et al.,2011)。因此,Cry毒素应用比较广泛的方式包括转基因作物和喷洒制剂以防控害虫。
Cry毒素的作用方式已被广泛研究,但机制仍存在争论(Soberon et al., 2009;Vachon et al.,2012)。现有2种作用模式解释Cry毒素的作用机制,即“穿孔模型”(Bravoet al.,2004)和“信号传导模型”(Zhang et al.,2006)。两种模型都认为,目标昆虫摄取Bt毒素,其后在碱性中肠环境中将其溶解,再由昆虫的消化蛋白酶激活。然后,活化的毒素(active toxins)会结合位于中肠细胞刷状缘膜囊泡((brush border membranevesieles,BBMV)上不同蛋白受体 (Knowles and Ellar,1987;Jurat-Fuentes andCrickmore,2017)。在穿孔模型中,活化的毒素可通过与特定钙粘蛋白(cadherin)结合而发生寡聚。接下来,毒素寡聚物与另一种受体蛋白如氨肽酶N(aminopeptidase N,APN)或碱性磷酸酶(alkalinephosphatase,ALP)结合,并插入中肠上皮细胞膜中形成空洞导致昆虫死亡(Pardo-Lopez et al.,2013;Adang et al.,2014)。最近,ABC转运蛋白已成为Cry毒素的关键功能受体,并被认为促进Cry毒素寡聚化和寡聚体穿孔(Heckel,2012;Ocelotl etal.,2017)。相比之下,信号传导模型中Cry毒素与中肠cadherin结合后,Mg2+依赖的cAMP信号通路被激活,从而导致细胞凋亡,并造成昆虫死亡(Zhang et al.,2005;Zhang et al.,2006)。这两种模型都表明,Cry毒素与cadherin的结合会触发复杂的多步骤反应过程。此外,在几种鳞翅目害虫中证实了cadherin突变与其对Cry毒素产生抗性相关(Fabrick etal.,2007;Gomez et al.,2001)。在烟芽夜蛾YHD2抗性品系中,钙粘蛋白基因表达的缺失蛋白已经与Cry1Ac毒素不存在结合区(Gahan,2001)。因此,钙粘蛋白在研究Bt杀虫活性和抗性机制的分子基础上是至关重要的受体(Gahan et al.,2001;Fabrick and Tabashnik,2007;Zhang et al.,2012)。
通过生物信息学对cadherin的结构进行预测,发现其二级结构包括氨基末端信号肽(amino-terminal signal peptide,SIG),细胞外结构区(包含9-14 个钙粘蛋白重复序列,cadherin repeats,CR),近膜端细胞外结构区 (membrane-proximal extracellulardomain,MPED),跨膜结构区 (transmembrane domain,TMD)和细胞质结构区(cytoplasmicdomain,CYT)。在鳞翅目昆虫的Cadherin中,Cry毒素结合区(toxin-binding region,TBR)主要位于靠近细胞膜的6个CR结构区(例如CR6-11/CR7-12)和MPED(Fabrick and Wu,2015)。发明人前期确定了小菜蛾cadherin片段(T1202-I1447, PxCad-TBR)及其来自棉铃虫的同源片段(T1217-L1461,HaCad-TBR)与Cry1Ac 毒素结合(Gao et al.,2019)。异源表达的含有TBR的钙粘蛋白片段以高亲和力结合Cry毒素,促进寡聚化并增强某些鳞翅目昆虫的Cry毒性(Chen et al., 2007;Fabrick et al.,2009;Pacheco et al.,2009b;Park etal.,2009; Park et al.,2019)。
钙粘蛋白是理解Cry毒素杀虫作用和抗性机制中一个重要的受体,对研究 Cry毒素与昆虫cadherin作用机制及设计特异性的杀虫蛋白具有重要意义。目前关于稻纵卷叶螟的cadherin基因,特别是毒素结合区的相关基因尚未见报道。
发明内容
针对上述问题,本申请首次从稻纵卷叶螟幼虫克隆得到一个cadherin基因 eDNA的全长序列,进而确定了它的核苷酸序列和氨基酸序列,并在此基础上定位了稻纵卷叶螟cadherin的Cry1Ac毒素结合区CmCad-CR6-MPED(G759-L1575) 编码基因,并进一步开发了其应用。
具体来说,本申请是通过如下技术方案实现的:
首先,本申请首次确定了稻纵卷叶螟钙粘蛋白Cry毒素结合区基因,其核苷酸序列如:SEQ ID NO.14所示;该基因位于稻纵卷叶螟钙粘蛋白基因全长序列 (如SEQ ID NO.10所示)的第2398-4848位;
其次,本申请定位了稻纵卷叶螟钙粘蛋白Cry毒素结合区基因的编码蛋白,其氨基酸序列如SEQ ID NO.15所示。该段蛋白位于稻纵卷叶螟钙粘蛋白氨基酸序列(如SEQ IDNO.11所示)的第759-1575位;
第三,本申请提供了上述稻纵卷叶螟钙粘蛋白Cry毒素结合区基因在预测稻纵卷叶螟Cry毒素抗性中的应用;若待测稻纵卷叶螟的钙粘蛋白Cry毒素结合区基因核苷酸序列与SEQ ID NO.14不同,则说明该稻纵卷叶螟受体发生基因突变,导致结合能力降低,判断昆虫对Cry毒素产生了抗性。
第四,本申请提供了上述稻纵卷叶螟钙粘蛋白Cry毒素结合区基因的编码蛋白在与Cry1Ac毒素结合中的应用。
第五,本申请提供了上述稻纵卷叶螟钙粘蛋白Cry毒素结合区基因的编码蛋白在筛选针对稻纵卷叶螟的Bt蛋白中的应用;若待筛选的Bt蛋白与Cry毒素结合区基因的编码蛋白CmCad-CR6-MPED具有高度亲和力,则必然会插入入稻纵卷叶螟中肠BBMV上,使上皮细胞膜形成孔洞致死,利用该编码蛋白 CmCad-CR6-MPED可以快速筛选或改造对稻纵卷叶螟具有高毒力的Bt毒素杀虫蛋白。
本申请在首次获得稻纵卷叶螟cadherin全长序列的基础上,预测了 CR6-MPED区(G759-L1575)作为CmCad候选的Cry1Ac毒素的毒素结合区。构建了CmCad-CR6-MPED重组蛋白并克隆至pET26b(+)载体中,在大肠杆菌BL21(DE3) 中表达并纯化。确定纯化的重组蛋白CmCad-CR6-MPED大小约120kDa。进一步确定了稻纵卷叶螟cadherin的毒素结合区CmCad-CR6-MPED与CrylAc毒素的结合,为CmCad作为CrylAc毒素的功能受体提供了可能性。该结合区的定位有助于研究对Bt毒素作用机制和抗性机制,并以此为基础设计更有效和特异性的杀虫蛋白用于鳞翅目农业害虫(特别是稻纵卷叶螟)的防治。

实施例1稻纵卷叶螟钙粘蛋白cadherin基因全长序列扩增
1.1稻纵卷叶螟钙粘蛋白cadherin基因保守区序列扩增
稻纵卷叶螟采自江苏省南京市(118°52’E,32°01’N),室内饲养数代后,选取龄期一致的4龄幼虫,使用Invitrogen Trizol试剂盒提取RNA,并使用 InvitrogenSuperScriptTMII Reverse Transcriptase试剂盒对总RNA反转录获得cDNA模板。稻纵卷叶螟属于鳞翅目螟蛾科(Pidralidae),使用生物信息学软件DNAMAN 9.0版对与其同一科的4个昆虫(O.nubilalis、O.furnacalis、 D.saccharalis和C.pressalis)的cadherin氨基酸序列进行比对(图1)。根据这4个昆虫钙粘蛋白的保守区特征,设计了一对简并引物(核苷酸序列如 SEQ ID No.1所示的上游引物CmCad-con-F,和核苷酸序列如SEQ ID No.2所示的下游引物CmCad-con-R),用来扩增稻纵卷叶螟钙粘蛋白保守区;然后以cDNA为模板,并使用I-5TM2×High Fidelity Master Mix(美国MCLAB公司)通过PCR 扩增,其中,IUBcode简并引物核苷酸代码:R=A/G;Y=C/T;H=A/C/T;N=A/C/G/T
PCR扩增体系为:2×High Fidelity MasterMix 25μl、10μM的CmCad-con-F 引物和CmCad-con-R引物各2μl、cDNA模板2μl、ddH2O补足至反应总体系50 μl;
PCR扩增条件:94℃5min;94℃30s,56℃30s,72℃1min 30s,共30个循环;72℃延伸10min,4℃保持。
PCR反应结束后,琼脂糖凝胶电泳检测PCR产物为2667bp的单一产物,并将对应的PCR纯化产物送至南京擎科生物公司测序。测序的结果经过氨基酸序列比对,所得到的保守序列同鳞翅目螟蛾科4个昆虫具有高度保守性,表明已获得所需要的保守氨基酸区域。该保守区核苷酸序列如SEQ ID No.3所示,大小为 2667bp,其对应的889个氨基酸残基序列如SEQ ID No.4所示。
1.2稻纵卷叶螟钙粘蛋白cadherin基因全长序列获得
以步骤1.1所获得的RNA为模板,使用Smart RACE cDNA amplification kit(Clontech)构建RACE cDNA文库,操作步骤按此试剂盒说明书进行。获得产物为 5’RACEReady cDNA和3’RACE Ready cDNA,分别作为5’RACE和3’RACE反应的模板。
根据步骤1.1所获得的保守区核苷酸序列(SEQ ID No.3)设计了两种特异性引物(核苷酸序列如SEQ ID No.5所示的引物CmCad-5’-R,和核苷酸序列如 SEQ ID No.6所示的引物CmCad-3’-F)。使用Smart RACE试剂盒自带的通用引物 Universal Primer A Mix(UPM,其核苷序列如SEQ ID No.7所示)和引物 CmCad-5’-R进行5’RACE PCR反应。使用引物UPM和引物CmCad-3’-F进行3’RACE PCR扩增。PCR反应条件:94℃30s,72℃3min,5个循环;94℃30s, 70℃3min,5个循环;对于5’RACE PCR,94℃30s,68℃30s,72℃3min,25 个循环。而对于3’RACE PCR,每个步骤的延伸时间均为2分钟,其他步骤与5’RACE 相同。将所得PCR产物克隆到pClone007载体(擎科生物)中,并通过南京擎科生物公司进行测序。
将所得5’和3’核苷酸序列与步骤1.1的保守区核苷酸序列进行拼接,得到稻纵卷叶螟cadherin基因全长cDNA序列。获得全长基因cDNA序列后,设计了一对引物(核苷酸序列如SEQ ID No.8所示的CmCad-full-F,和核苷酸序列如SEQ ID No.9所示的CmCad-full-R),用于验证稻纵卷叶螟钙粘蛋白的开放阅读框(Open Reading Fram,ORF)。最后将所获得得5,455bp全长序列CmCad cDNA (SEQ ID No.10)提交至NCBI数据库(GenBank NCBI登录号MN796259.1)。
序列分析表明,克隆的cDNA序列包含一个5,175bp的ORF,一个123bp 的5’非翻译区(UTR)和一个157bp的3’-UTR,其中包含26bp的poly(A) 尾巴。经典的多腺苷酸化信号序列之一ATTAAA位于poly(A)尾部上游20bp。 CmCad cDNA编码1725个氨基酸(SEQ IDNo.11),预测分子量为192.85kDa, pI为4.06。
扩增所涉及的所有引物序列除UPM为试剂盒自带以外,均为南京擎科生物公司人工合成。
实施例2稻纵卷叶螟钙粘蛋白CmCad序列的结构与进化分析
使用ISRECProfile服务器(https://myhits.isb-sib.ch/cgi-bin/PFSCAN) 分析稻纵卷叶螟钙粘蛋白CmCad的二级结构特征。使用MEGA 7.0软件,通过邻位连接法(theneighbor-joining method)构建系统进化树,节点处的数字为 1000次重复的自展置信值(bootstrap values)。
预测的CmCad二级结构由信号肽(SIG)、11个cadherin重复序列(CR)、近膜胞外区(MPED)、跨膜区(TMD)和胞质区(CYT)组成,显示为典型的昆虫中肠 Cadherin结构(图2A)。
为研究来自不同昆虫物种的cadherin的进化关系,使用邻接法构建系统发育树(图2B),结果显示,3个蛱蝶科、3个粉蝶科、3个凤蝶科、2个蚕蝶科、 2个毒蛾科、2个裳蛾科、6个螟蛾科和9个夜蛾科(Trichoplusiani形成另一个簇)的Cadherin分别根据所属科进行聚类(图2B)。CmCad与欧洲玉米螟(O. nubilalis)和亚洲玉米螟(O.furnacalis)的cadherin聚集在一起(图2B)。
实施例3稻纵卷叶螟钙粘蛋白Cry毒素结合区的构建、表达和纯化
鳞翅目昆虫中钙粘蛋白Cry毒素的TBR主要位于靠近细胞膜的6个CR结构区(例如CR6-11/CR7-12)和MPED。具体到稻纵卷叶螟的CR6-MPED,为共计817 个氨基酸,对此进截短的CmCad-CR6-MPED片段行构建、表达和纯化(J.Zhong, X.Hu,X.Zhang,Y.Liu,C.Xu,C.Zhang,M.Lin,X.Liu.Broad specificity immunoassay for detection of Bacillusthuringiensis Cry toxins through engineering of a single chain variablefragment with mutagenesis and screening.International Journal of BiologicalMacromolecules,2018,107: 920-928.)。具体为:分别使用含有NcoI和NotI限制性酶切位点的正向引物(核苷酸序列如SEQ ID No.12所示的CmCad-CR6-MPED-F,)和反向引物(核苷序列如 SEQ ID No.13所示的CmCad-CR6-MPED-R)扩增CmCad-CR6-MPED片段,引物序列为南京擎科生物公司人工合成。
扩增采用I-5TM2×PCR Master Mix,以pClone007-CmCad质粒为模板,98℃ 2min,98℃20s,58℃20s,30个循环,72℃1min,最后的延伸步骤是72℃5min。
PCR产物用琼脂糖凝胶DNA提取试剂盒(Axygen)纯化,并使用NcoI和 NotI酶切位点亚克隆到pET-26b(+)载体(Novagen)中。将连接产物转化到大肠杆菌(E.coli)BL21(DE3)感受态细胞(全式金生物公司)中。通过测序验证成功转化的重组质粒及核苷酸序列(南京擎科生物公司)。
经测序确认的pET-26b-CmCad-CR6-MPED重组蛋白在含有50μg/ml卡那霉素(kanamycin)(索莱宝公司)的2×TY培养基中培养,37℃、250rpm培养至对数生长后期(OD600=0.5-0.6),加入1mM异丙基-β-D-硫代半乳糖苷 (isopropyl-β-D-thiogalactopyranoside,IPTG)(索莱宝公司),然后在 30℃、220rpm下再培养14h诱导CmCad-CR6-MPED的表达。诱导表达的细胞在8,000×g下离心15min,在pH 7.4的PBS中重悬沉淀,并通过超声破碎裂解。细胞裂解产物在12,000×g离心30min,沉淀中的包涵体溶解在8M尿素中,在Labquake Shaker Rotisserie(Thermo Fisher Scientific公司)上4℃缓慢旋转孵育过夜。溶解的重组蛋白在HiTrap Ni2+柱(GE Healthcare公司)上纯化。CmCad-CR6-MPED用100mM咪唑洗脱,然后在含6M、4M、2M且无尿素的PBS 中逐渐透析以去除残留的尿素和咪唑。CmCad-CR6-MPED的纯度通过10%SDS-PAGE 进行评估,并通过Bradford蛋白检测试剂盒(索莱宝公司)确定蛋白浓度。
为了检测CmCad-CR6-MPED重组蛋白的表达,采用了Western blotting方法。将2.0μg纯化蛋白通过10%SDS-PAGE分离,然后电转移至聚偏二氟乙烯 (polyvinylidenedifluoride,PVDF)膜(Millipore公司)。转移后,室温下将 PVDF膜在封闭缓冲液(含有0.1%Tween-20和3%BSA的PBS,PBST)中封闭1h,然后用抗His标签抗体(1∶7,500稀释)(康为世纪生物公司)孵育1h。印迹用洗涤缓冲液(含有0.1%Tween-20的PBS,PBST)洗涤5次,每次10分钟,然后使用ChromoSensor试剂(GenScript公司)在室温下显色2-3分钟,并使用分辨率高的数码相机拍照。
根据鳞翅目昆虫cadherin描述的Cryl毒素结合区的同源性特征,本实施例预测了CR6-MPED区(G759-L1575)作为CmCad候选的Cry1Ac毒素的毒素结合区(图3A)。构建了CmCad-CR6-MPED重组蛋白并克隆至pET26b(+)载体中,在大肠杆菌BL21(DE3)中表达,在IPTG诱导下并通过SDS-PAGE确定诱导蛋白的数量(图3B,泳道:1-4)。由于表达的CmCad-CR6-MPED重组蛋白带有His标签,使用HiTrap Ni2+柱纯化后,所表达的蛋白约为120kDa(图3B,泳道:5)。 Western blotting进一步检测,pET26b空载体与抗His标签抗体没有结合(图3C,泳道:6),纯化的重组蛋白CmCad-CR6-MPED与抗His标签抗体结合大小(约 120kDa)(图3C,泳道:7)与SDS-PAGE结果一致。这些结果表明120kDa左右的条带是表达的重组蛋白CmCad-CR6-MPED,其核苷酸序列如SEQ ID NO.14所示,氨基酸序列如SEQ ID NO.15所示。
实施例4稻纵卷叶螟钙粘蛋白Cry毒素结合区与Cry1Ac的结合
Cry1Ac毒素购自Envirotest-China(Envirologix Inc),并溶解在碳酸钠缓冲液(CBS,pH 9.6)中,分装并储存于-80℃直至使用。使用EZ-Link Sulfo-NHS-SS-Biotinylation试剂盒(Thermo Fisher Scientific)对可溶性 Cry毒素进行生物素标记,并按照试剂盒说明书进行操作。具体为:28.4μL 10 mM生物素用于标记1mL终体积反应中的1mg Cry毒素。在室温下缓慢旋转反应2h,然后通过脱盐柱去除过量的生物素试剂。通过使用辣根过氧化物酶 (horseradish peroxidase,HRP)偶联的链霉亲和素(streptavidin)(Thermo Fisher Scientific)结合Western blotting检测生物素标记效率。使用Bradford法测定生物素化Cry毒素的浓度。
为了检测CrylAc和CmCad-CR6-MPED之间的结合,使用ligand blotting 方法。具体方法跟上述Western blotting检测基本一致,不同之处在于封闭缓冲液封闭后,将PVDF膜与20nM生物素标记的Cry毒素在室温下孵育1h。PBST 洗涤5次后,然后用streptavidin-HRP(1∶7,500稀释)结合PVDF膜1h。最后显色方法跟前述Western blotting检测一样。
为了进一步确定CmCad-CR6-MPED重组蛋白与CrylAc毒素的结合,使用生物素标记的CrylAc对表达的重组蛋白进行ligand blotting分析。检测结果如图4A所示,Westernblotting结果表明了通过streptavidin-HRP检测证实了生物素标记的CrylAc毒素。ligandblotting分析的结果确定了CrylAc毒素与 CmCad-CR6-MPED重组蛋白的结合(图4B)。
稻纵卷叶螟cadherin的CrylAc毒素结合区定位到CmCad-CR6-MPED (G759-L1575)上,而且抗性机制主要是Cry毒素与昆虫BBMV上的受体蛋白结合能力的降低有关,所以当受体发生突变导致结合能力降低时,可以判断昆虫对Cry毒素产生了一定抗性。稻纵卷叶螟cadherin的CrylAc毒素结合区可以在分子水平检测该虫种是否产生了抗性成为可能。
另外,本申请明确了稻纵卷叶螟cadherin与CrylAc毒素发生结合的区域,如果某种Bt蛋白与该结合区具有高度亲和力,必然会插入入稻纵卷叶螟中肠 BBMV上,使上皮细胞膜形成孔洞致死,利用这种方法可以快速筛选或改造对稻纵卷叶螟具有高毒力的Bt杀虫蛋白。
