Description
技术领域
本发明涉及植物的基因工程,特别是抗昆虫的转基因棉花植物。本发明也涉及检测来源于该植物的材料的方法。
背景技术
植物害虫是世界上重要农作物损失的主要因素。在美国,由于非哺乳动物害虫(包括昆虫)侵袭植物,每年损失约80亿美元。除了农田作物损失外,昆虫害虫对于蔬菜和水果种植者,对于观赏花卉的生产者,和对于家宅园丁也是负担。
主要通过化学杀虫剂的广泛应用控制昆虫害虫,该化学杀虫剂具有抑制昆虫生长,妨碍昆虫进食或繁殖,或引起死亡的活性。因此可以达到良好的昆虫害虫控制,但是这些化学药品有时也影响其它有益昆虫。化学杀虫剂广泛应用引起的另一问题是抗药性昆虫品种的出现。通过各种抗药性处理实践已经部分缓解了这种现象,但是对可替代的害虫控制剂存在日益增加的需要。生物害虫控制剂,诸如表达杀虫毒素象δ-内毒素的苏云金芽孢杆菌(Bacillus thuringiensis)株系也已经被施用给作物植物,并且取得了满意的结果,提供了化学杀虫剂的可替代物或补充物。已经分离了一些编码这些δ-内毒素的基因,表明在异源宿主中它们的表达提供了用于经济上重要的昆虫害虫控制的另一种工具。特别地,转基因植物中杀虫毒素如苏云金芽孢杆菌(Bacillus thuringiensis)δ-内毒素的表达提供了免受所选择昆虫害虫侵害的有效保护,并且已经商品化了表达这种毒素的转基因植物,使得农民能够减少化学昆虫控制药剂的施用。
最近,鉴定了芽孢杆菌属(Bacillus spp.)营养生长阶段期间产生的一类新的杀虫蛋白质(营养杀虫蛋白质(VIPs))。美国专利5,877,012,6,107,279,和6,137,033描述了从芽孢杆菌属(Bacillus)物种分离的vip3A毒素基因。VIP3A毒素具有抗广谱鳞翅目昆虫,包括但不限于草地贪夜蛾(Spodoptera frugiperda),小地老虎(Agrotis ipsilon),小蔗螟(Diatraea saccharalis)和南美玉米苗斑螟(Elasmopalpuslignosellus)的杀虫活性,并且当在转基因植物例如棉花中表达它时,给植物提供了免受昆虫进食损害的保护。
棉类植物棉属(Gossypium)是锦葵科(Malvaceae)的成员,包含39个物种,其中陆地棉(Gossypium hirsutum)是最常栽培的物种。也栽培3种其它物种:树棉(G.arboreum),海岛棉(G.barbadense)和草棉(G.herbaceum)。种植这些栽培品种主要是为了制成纺织品的种子纤维。棉花适于做为纺织纤维,因为成熟的干纤维捻在一起,使得可从中纺出结实的细线。其它产品,诸如棉籽油、油饼和棉籽绒是纤维生产的副产品。
每年,世界上由于昆虫害虫对棉花作物的损害引起了严重的产量损失。有效地控制这些害虫以最小化产量损失具有重要的经济意义。棉花昆虫害虫的例子包括甜菜夜蛾(Spodoptera exigua),棉铃象(Anthonomusgrandis grandis),粉纹夜蛾(Trichoplusia ni),云纹盲蝽(Neurocolpusnubilus),棉蚜(Aphis gossypii),谷实夜蛾(Heliocoverpa zea),切根虫(粒肤地虎(Feltia subterranean),豆杂色夜蛾(Peridroma saucia),小地老虎(Agrotis ipsilon)),欧洲玉米螟(Ostrinia nubilalis),草地贪夜蛾(Spodoptera frugiperda),花蓟马属(Frankliniella spp.),大豆夜蛾(Pseudoplusia includens),蝽象(稻绿蝽(Nezara viridula),喜绿蝽(Acrosternumhilare),褐臭蝽(Euschistus servus)),牧草盲蝽(Lygus lineolaris),烟蚜夜蛾(Heliothis virescens)和粉虱(结翅粉虱(Trialeurodes abutilonea),甘薯粉虱(Bemisia tabaci))。
现在,棉花植物的转化和再生是非常完善的方法,典型地基于根瘤农杆菌(Agrobacterium tumfaciens)介导外源DNA转移到棉花植物部分中,并且在组织培养中再生所述植物部分为完全可育的转基因棉花植物。
需要产生抗昆虫的棉花植物,以减少由于昆虫害虫对棉花作物的损害造成的产量损失。抗昆虫棉花植物可以减少施用化学杀虫剂的需要,化学杀虫剂可能对其它有益昆虫和环境是有害的。
发明内容
因此,本发明涉及命名为COT102的抗昆虫转基因棉花事件。本发明也涉及检测来源该事件的植物材料的方法。在本申请上下文中“COT102事件”指这里所述的原始杀虫转基因棉花植物。这里所用的“杀虫”指对昆虫的任何抑制作用,包括但不限于进食减少、生长阻滞、生殖力减弱,麻痹或死亡。“生殖力”包括与繁殖有关的所有方面,诸如繁殖能力、繁殖频率和后代数量。本发明也包括来源于该COT102事件的任何植物材料,包括种子。
COT102事件显示了包含2个表达盒的新基因型。第一个盒子包含用于在植物中表达的适合启动子和适合的聚腺苷酸化信号,该启动子可操作地连接编码VIP3A杀虫毒素的基因,该VIP3A杀虫毒素可用于控制广谱鳞翅目昆虫害虫。尤其可以从植物分离适合的启动子。已经分离和表征了大量植物启动子,包括组成型、开关型和/或组织特异性启动子。适合的启动子可以选自下列非限制性的群组:CaMV35S,FMV35S,遍在蛋白,Act2,NOS,OCS,夜香树属(Cestrum)黄叶卷曲病毒启动子,Patatin,E9,alcA/alcR开关,GST开关,RMS开关,油质蛋白,Gelvin,核酮糖二磷酸羧化酶-加氧酶小亚基,肌动蛋白7,MR7启动子(玉米),Gos9(水稻),GOS2启动子,MasOcs(或超启动子(super promoter)),RolD启动子(毛根农杆菌(Agrobacterium rhizogenes)),SuperMAS启动子和Suc2启动子(拟南芥属(Arabidopsis))。在本发明的一个实施方式中,启动子是来源于拟南芥属(Arabidopsis)的肌动蛋白启动子Act2。另外的元件诸如增强子序列也可以掺入表达盒中以加强基因表达水平,例如转录或翻译增强子,诸如烟草蚀刻病毒(TEV)翻译激活子(translationactivator),CaMV35S增强子和FMV35S增强子。做为可替代方案,可能期望包含导向序列,例如以引导VIP3A毒素转运到特定细胞区室。例如,如果期望提供细胞外蛋白质,那么可以连接细胞外导向序列和编码VIP蛋白质的多核苷酸。其它靶向的例子包括靶向特定的细胞内细胞器或区室,例如利用‘KDEL’保留序列,靶向内质网。已经分离和表征了大量聚腺苷酸化信号。植物中起作用的适合聚腺苷酸化信号的例子包括来源于根瘤农杆菌(Agrobacterium tumefaciens)胭脂氨酸合酶基因(nos),来源于蛋白酶抑制剂基因II和来源于α-微管蛋白基因的聚腺苷酸化信号(EP-A 652,286)。在本发明一个实施方式中,聚腺苷酸化信号是来源于根瘤农杆菌(Agrobacterium tumefaciens)nos基因的聚腺苷酸化信号。
根据本发明,也可以密码子优化或者以其它方式改变编码VIP3A蛋白质的多核苷酸,这样一旦该多核苷酸被掺入到植物材料中,例如就可以增强转录。这种密码子优化也可以用于改变任何转化细胞中产生的RNA转录物的预测二级结构,或者用于破坏未改变的转录物中存在的隐蔽RNA不稳定性元件,因此增加转化细胞中转录物的稳定性和可利用性(Abler和Green(1996)Plant Molecular Biology(32),63-78页)。
第二个盒子包含当表达时可以用做选择性标记的基因。已经表征了大量选择性标记,包括赋予对抗生素耐受性的一些选择性标记和赋予对除草剂耐受性的其它选择性标记。适合的选择性标记基因的例子包括赋予对潮霉素、卡那霉素或庆大霉素耐受性的选择性标记基因。其它适合的选择性标记包括赋予对除草剂诸如基于草甘膦的除草剂的耐受性或对毒素诸如eutypine的抗性的基因。也可以利用其它形式筛选诸如基于激素的筛选系统诸如Hiroyrasu Ebinuma等(1997)PNAS,94卷,2117-2121页的多自动转化(MAT)系统;使用已知绿色荧光蛋白、β-葡糖醛酸酶的可观察的筛选系统和任何其它筛选系统诸如甘露糖异构酶(PositechTM),木糖异构酶和2-脱氧葡萄糖(2-DOG)。在本发明一个实施方式中,选择性标记基因是赋予对潮霉素耐受性的选择性标记基因。其它表达盒可选地包含在COT102事件中。例如,这些表达盒可以提供其它的期望益处诸如除草剂抗性。
第一和第二个表达盒可以在相同或不同质粒上被引入植物中。如果第一和第二表达盒存在相同质粒上,并且通过农杆菌属(Agrobacterium)介导的转化方法被引入到植物中,则它们可以存在于相同或不同T-DNA区中。在本发明一个实施方式中,第一和第二个表达盒存在于相同T-DNA区上。
根据本发明的第一方面,提供了多核苷酸,其包含来自于SEQ ID NO:1的26个核苷酸序列的至少17个邻接核苷酸。在一个实施方式中,所述多核苷酸包含来自于SEQ ID NO:1的至少18个邻接核苷酸。在进一步实施方式中,所述多核苷酸包含来自于SEQ ID NO:1的至少20个邻接核苷酸。在另一实施方式中,所述多核苷酸包含来自于SEQ ID NO:1的至少22个邻接核苷酸。在进一步实施方式中,所述多核苷酸包含来自于SEQ IDNO:1的至少24个邻接核苷酸。在进一步实施方式中,本发明提供了包含SEQ ID NO:1序列的多核苷酸。
在本发明另一个方面,提供了多核苷酸,其包含来自于SEQ ID NO:2的26个核苷酸序列的至少17个邻接核苷酸。在一个实施方式中,所述多核苷酸包含来自于SEQ ID NO:2的至少18个邻接核苷酸。在进一步实施方式中,所述多核苷酸包含来自于SEQ ID NO:2的至少20个邻接核苷酸。在进一步实施方式中,所述多核苷酸包含来自于SEQ ID NO:2的至少22个邻接核苷酸。然而,在进一步实施方式中,所述多核苷酸包含来自于SEQ ID NO:2的至少24个邻接核苷酸。在再进一步实施方式中,本发明提供了包含SEQ ID NO:2序列的多核苷酸。
在本发明另一方面,提供了包含SEQ ID NO:7序列的上述多核苷酸。在本发明另一方面,提供了包含SEQ ID NO:21序列的上述多核苷酸。
在本发明另一方面,提供了一种包含多核苷酸的植物,该多核苷酸包含SEQ ID NO:1和/或SEQ ID NO:2的至少17个邻接核苷酸。在一个实施方式中,所述植物包含SEQ ID NO:1和/或SEQ ID NO:2的至少18个邻接核苷酸。在进一步实施方式中,所述植物包含SEQ ID NO:1和/或SEQ IDNO:2的至少20个邻接核苷酸。在进一步实施方式中,所述植物包含SEQ IDNO:1和/或SEQ ID NO:2的至少22个邻接核苷酸。在进一步实施方式中,所述植物包含SEQ ID NO:1和/或SEQ ID NO:2的至少24个邻接核苷酸。然而,在进一步实施方式中,所述植物包含SEQ ID NO:1和/或SEQ ID NO:2的序列。还是在进一步实施方式中,所述植物还包含SEQ ID NO:7序列。在另一个实施方式中,所述植物包含SEQ ID NO:21序列。在本发明一个实施方式中,所述植物是棉花植物。在进一步实施方式中,所述植物是作为COT102事件的杀虫棉花植物,或者来源于它的植物。
本领域技术人员熟悉植物转化方法。特别地,已经在广泛植物物种中表征了两种主要的技术:通过农杆菌属(Agrobacterium)的转化和通过直接DNA转移的转化。
农杆菌属(Agrobacterium)介导的转化是用于双子叶植物转化的常用方法。将要引入到植物中的外源DNA克隆到双元载体的左和右边界共有序列之间。这是T-DNA区。双元载体被转化到农杆菌属(Agrobacterium)细胞中,随后,该农杆菌属(Agrobacterium)细胞用于感染植物组织。包含外源DNA的载体T-DNA区被插入到植物基因组中。标记基因盒和性状基因盒可以存在于相同载体中的相同T-DNA区上,不同T-DNA区上,或者甚至是不同载体中的不同T-DNA区上。在本发明的一个实施方式中,这些盒子存在于相同T-DNA区上。
做为可替代方案,直接DNA转移可以用于将DNA直接引入到植物细胞中。直接转移的一个适合方法可以是利用基因枪,用包含插入用DNA的载体轰击植物细胞(粒子介导的生物弹击转化);另一种确立的方法是‘whiskers’,其包括将DNA包被到刺穿细胞的碳化硅纤维上。转化植物细胞的其它方法包括原生质体转化(可选地在聚乙二醇存在的情况下);在包含多核苷酸或载体的介质中超声处理植物组织、细胞或原生质体;多核苷酸或载体显微插入到植物材料中(可选地利用已知的碳化硅‘whiskers’技术),电穿孔等等。
转化后,必须从转化的植物组织再生转基因植物,并且利用适合的标记诸如潮霉素抗性标记选择具有外源DNA的后代。本领域技术人员熟悉适当再生介质的组成。
如这里所述,本发明这方面的植物对来自于实夜蛾属(Heliothissp.),Helicoverpa sp.和贪夜蛾属(Spodoptera sp.)的一个或多个物种的、可能侵袭该植物的昆虫具有杀虫作用。这里所用的“侵袭”指一种或多种昆虫以任何方式的攻击、进食或损害。因此,例如,本发明植物将提供抗害虫昆虫诸如谷实夜蛾(Helicoverpa zea)侵袭的自卫机制。结果,与相同品种非转基因棉花植物比较,在所述植物栽培期间需要减少数量的杀虫喷雾剂。并且昆虫害虫造成的产量损失保持在最小水平。
本发明不限于COT102事件本身,而是进一步延及包括来源于其的任何植物材料,包括种子,只要它们含有至少一种本发明多核苷酸。本发明包括但不限于来源于与COT102事件育种杂交的植物,或者通过常规育种或其它方法由此来源的衍生物。本发明也包括来源于COT102事件的植物材料,该植物材料与COT102事件比较,可以包含另外的、修饰的或较少的多核苷酸序列,或者显示其它的表型特征。例如,可能期望转化来源于COT102事件的植物材料以产生具有另外性状诸如第二昆虫抗性基因的新事件。这个方法称为基因堆积(gene stacking)。第二个昆虫抗性基因可以编码例如来源于苏云金芽孢杆菌(Bacillus thuringiensis),嗜线虫致病杆菌(Xenorhabdus nematophilus),发光光杆状菌(Photorabdusluminescens)物种的杀虫凝集素,杀虫蛋白酶抑制剂和杀虫蛋白质。
优选地,第二个昆虫抗性基因编码来源于细菌苏云金芽孢杆菌(Bacillus thuringiensis)的Cry基因,该Cry基因产生具有和VIP不同的作用方式或昆虫肠道中的结合位点的毒素用以控制不同的昆虫物种。本发明进一步提供了来源于COT102事件的植物材料,该植物材料具有另外的性状诸如除草剂抗性、线虫抗性或真菌抗性。在一个实施方式中,所述另外性状是除草剂抗性。在进一步实施方式中,所述除草剂抗性性状提供了对包含草甘膦酸或农业学上可接受的其盐的除草剂的抗性。还是在进一步实施方式中,由编码EPSP合酶或其突变体的基因提供所述的除草剂抗性性状。
本发明进一步提供了控制昆虫的方法,该方法包括在所述昆虫取食地点,提供来源于COT102事件的植物材料。本发明进一步提供了控制昆虫的方法,该方法包括在所述昆虫取食地点,提供来源于COT102事件的植物材料,并且给所述植物材料施用其它农用化学品诸如除草剂、杀真菌剂和包括其它杀虫蛋白质的其它杀虫化合物。可能的杀虫化合物的例子包括杀虫凝集素、杀虫蛋白酶抑制剂和来源于苏云金芽孢杆菌(Bacillusthuringiensis),嗜线虫致病杆菌(Xenorhabdus nematophilus)或发光光杆状菌(Photorabdus luminescens)物种的杀虫蛋白质。可能的化学药品的例子包括合成除虫菊酯类、氨基甲酸酯类、吡虫啉、有机氯制剂和大分子诸如多杀菌素,阿维菌素或依马菌素。
然而,根据本发明的另一方面,本发明提供了检测来源于COT12转基因事件的植物材料的方法,该方法包括获得用于分析的样品;从样品提取DNA;提供设计用于结合多核苷酸的引物对,该多核苷酸包含SEQ ID NO:1和/或SEQ ID NO:2的至少17个邻接核苷酸;扩增位于引物结合位点之间的区域;并且检测扩增产物的存在。因为可以得到SEQ ID NOs1和2,所以可以利用分子生物学领域技术人员熟知的参数,设计该检测方法中使用的适合引物对。例如,可以将引物对的1个或2个引物设计成载体特异性,性状基因特异性,启动子特异性的,或者对插入DNA和基因组DNA之间连接处序列特异和/或标记特异性的。在一个实施方式中,所述引物序列如SEQ ID NO:3和SEQ ID NO:4所描述。
在本发明一个实施方式中,用所述方法扩增的区域(“扩增子”)长度是在300和1000碱基对之间。在进一步实施方式中,扩增子长度是在500和900碱基对之间。还是在进一步实施方式中,扩增子长度是800碱基对。在进一步实施方式中,利用上述方法,联合序列SEQ ID NO:3和SEQ ID NO:4引物产生了扩增子,并且其长度是800碱基对。
可以联合使用以检测COT102事件的可替代引物包括对COT102事件特异并且产生962bp扩增子的SEQ ID NOs 18和19,对VIP基因特异并且产生556bp扩增子的SEQ ID NOs 22和23,或者对赋予对抗生素潮霉素抗性的基因特异并且产生367bp扩增子的SEQ ID NOs 24和25。
根据本发明的这方面,有许多可以使用的扩增方法。基本的原理,本领域技术人员已知的技术,是聚合酶链式反应(PCR)。典型地在利用琼脂糖凝胶电泳大小分离后,通过用溴化乙锭染色和用UV光激发可以观察来自于该PCR反应的扩增产物。
本发明的一个实施方式利用了PCR原理的变型诸如TaqManTM。这种方法包括用荧光染料标记参与扩增过程的至少一个引物。当未结合时,引物采取检测不到荧光的构象。然而,当引物结合一段DNA时,构象改变,并且可以检测到荧光。用这种方式,可以实时监测扩增过程,荧光的强度直接对应于扩增的水平。本发明的进一步实施方式包括,但不限于RACE PCR。
本发明的进一步实施方式包括利用多重PCR(multiplex PCR)区分纯合COT102植物材料和杂合COT102植物材料。本领域技术人员称之为接合性测试(zygosity testing),并且其包括结合棉花基因组和/或插入DNA的特定部分的3种PCR引物的使用。用在这种接合性测试中的适合引物被描述为SEQ ID NOs 18到20。
本发明的另一个方面提供了检测来源于COT102事件的植物材料的方法,该方法包括获得用于分析的样品;提供探针,该探针被设计成当多核苷酸是单链时结合所述多核苷酸的互补序列,该多核苷酸包含SEQ IDNO:1和/或SEQ ID NO:2的至少17个邻接核苷酸;杂交所述探针和样品;并且检测该探针是否已经杂交。在一个实施方式中,所述探针包括SEQ IDNO:1和/或SEQ ID NO:2序列。在本发明一个实施方式中提供了利用选自SEQ ID NO:5,SEQ ID NO:6和SEQ ID NO:7的探针,检测来源于COT102事件的植物材料的方法。在一个实施方式中,所述探针包含SEQ ID NO:5。在进一步实施方式中,所述探针由SEQ ID NO:5组成。例如,探针可以是PCR产物或限制消化片段。在进一步实施方式中,可以用荧光、放射性、酶性或其它适合的标记标记这里所述的探针,以能够检测到杂交。由于本领域技术人员已经从本公开受益,所以他们将知道如何设计适合的引物。
在本发明进一步实施方式中,提供了在严格条件下杂交探针和样品,并且检测探针是否已经杂交的方法。严格杂交条件是本领域技术人员所熟知的,并且包括,例如在约65℃,在含有6x SSC,0.01%SDS和0.25%脱脂奶粉的溶液中杂交,接着在相同的温度,在含有0.2x SSC和0.1%SDS的溶液中洗涤。
基于杂交原理,用于检测来源于COT102事件的植物材料的适合技术包括但不限于Southern印迹,Northern印迹和原位杂交。本领域技术人员熟悉这些技术。
典型地,这些技术包括温育探针和样品,洗涤以移除未结合的探针和检测探针是否已经杂交。所述的检测方法取决于探针所附标记的类型,例如,通过X光片曝光和显影可以检测放射性标记的探针。做为可替代的方案,通过底物转化实现颜色变化可以检测酶标记的探针。
在本发明的进一步方面,提供了检测来源于COT102事件的植物材料的方法,该方法包括获得用于分析的样品;提供设计的抗体,该抗体可结合植物中所包含的VIP蛋白质,该植物包含来源于SEQ ID NO:1和/或SEQID NO:2的至少17个邻接核苷酸;温育所述的抗体和样品;检测是否该抗体已经结合。在本发明的一个实施方式中,所述VIP蛋白质包含SEQ IDNO:8序列。
基于所述抗体结合,检测来源于COT102事件的植物材料的适合方法包括,但不限于Western印迹,酶联免疫吸附测定法(ELISA)和SELDI质谱分析。本领域技术人员熟悉这些免疫学技术。典型的步骤包括:温育样品和结合VIP蛋白质的抗体,冲洗以移除未结合的抗体,和检测是否抗体已经结合。许多这种检测方法是基于酶促反应的,例如可以用酶诸如辣根过氧化物酶标记抗体,并且在应用适合的底物后,检测颜色改变。适合的抗体可以是单克隆或多克隆抗体。
在本发明的另一方面,提供了检测来源于COT102事件的植物材料的方法,该方法包括获得用于分析的样品;制备样品的蛋白质提取物;提供设计用来检测样品中VIP蛋白质的存在的检测条;温育检测条和样品;和检测VIP蛋白质是否存在。在本发明的一个实施方式中,所述VIP蛋白质包含SEQ ID NO:8序列。
用于COT102的可替代的基于抗体的检测方法利用测量棒(dipsticks)或检测条。典型的步骤包括温育检测条和样品,并且观察检测条上存在或不存在有色条带。有色条带表明样品中蛋白质的存在。这种测量棒(dipsticks)或检测条检测是蛋白质特异性的,并且可以用于田地中样品的快速检测。
在本发明的进一步方面,提供了检测来源于COT102事件的植物材料的方法,该方法包括获得用于分析的样品;使物种草地贪夜蛾(Spodopterafrugiperda)(对VIP3A敏感)的一个或多个昆虫暴露于样品;使物种欧洲玉米螟(Ostrinia nubilalis)的一个或多个昆虫暴露于样品,做为对照;检测是否样品对来源于每个物种的昆虫具有杀虫作用;并且比较该结果和真实的COT102生物测定模式(bioassay profile)。利用相同条件的昆虫产生真实COT102生物测定模式,其中,将该昆虫暴露于相同剂量和类型COT102植物材料,并且在将昆虫暴露于COT102样品后相同长度的时间检测杀虫作用。草地贪夜蛾(Spodoptera frugiperda)是COT102阳性对照,因为它对适合剂量的VIP3A敏感,而欧洲玉米螟(Ostrinianubilalis)是阴性对照,因为它对适合剂量的VIP3A不敏感。
在本发明一个实施方式中,检测来源于COT102事件的植物材料的方法包括但不限于叶片饲喂的生物测定法,其中用一种或多种害虫昆虫侵袭COT102事件或者来源于COT102事件的任何植物材料的叶片或其它适合的植物部分。通过在给定时间期间后估测叶片或植物部分的损害,估测死亡率或对昆虫的另一种杀虫作用可以进行检测。可以用于这种生物测定的可替代植物部分包括棉铃和棉蕾。可以在田地或温室中进行这种生物测定,并且可以经历天然或人工昆虫侵袭。
在本发明另一方面,本发明提供了试剂盒(kit of parts),其包含用于检测样品中来源于COT102事件的植物材料存在的手段(means)。优选地,所述试剂盒包含用于检测样品中多核苷酸或上述多核苷酸编码的蛋白质或VIP蛋白质存在的手段,该多核苷酸包含来源于SEQ ID NO:1和/或SEQ ID NO:2的至少17个邻接核苷酸。在本发明的实施方式中,所述试剂盒可以包含DNA扩增检测技术诸如PCR或TaqManTM。在本发明的进一步实施方式中,所述试剂盒可以包含探针杂交检测技术诸如Southern印迹,Northern印迹或原位杂交。在本发明另一个实施方式中,所述试剂盒可以包含抗体结合检测技术诸如Western印迹,ELISAs,SELDI质谱分析或检测条。在本发明的进一步实施方式中,所述试剂盒可以包含昆虫生物测定检测技术诸如叶片饲喂生物测定或死亡率生物测定。在本发明进一步实施方式中,所述试剂盒可以包含上述检测技术的任意组合。还是在进一步实施方式中,所述试剂盒可以以说明书形式包含上述一种或多种方法。
