Description

抗虫基因VIP3m及其应用
技术领域
本发明涉及基因工程领域,具体地说,涉及一种抗虫基因VIP3m及其应用。
背景技术
虫害是造成农作物严重减产的一个主要因素,防治农业害虫最常见的手段是使用化学杀虫剂和生物杀虫剂。化学杀虫剂多具有广谱、高毒的特点,在杀死目标害虫的同时往往将很多益虫一起杀死,严重破坏生态平衡,并对环境造成严重污染;此外,农药残留对人类、牲畜的健康也造成严重威胁。生物杀虫剂具有易降解,与环境高度相容的特点,但在生产上需要重复施用,大大增加了生产成本。为了弥补化学杀虫剂和生物杀虫剂在农业生产应用中的弊端,科学家们将能编码杀虫蛋白的基因导入到植物体内,培育出多种转基因植物。
目前,人们已经克隆了数百种Bt杀虫蛋白基因,但这些杀虫蛋白基因真正能应用于生产的却屈指可数,其原因主要是毒力较低,在转基因作物中表达量低,容易使害虫产生抗性;除此之外,杀虫蛋白基因克隆资源的日渐匮乏也给基因克隆造成很大难度。因此,有必要创制具有杀虫活性的新型Bt基因,并利用这些基因转化玉米创制转基因玉米新材料。

实施例1 VIP3m基因的改造合成
本发明提供一种对草地贪夜蛾具有杀虫活性的杀虫蛋白基因VIP3m及其编码蛋白。
根据玉米密码子偏好性对来自苏云金芽孢杆菌(Bacillus thuringiensis,Bt)的VIP3蛋白(GenBank No.48811.1)的编码基因进行优化,G+C含量由原来的30.9%提高到59.9%,进一步提高VIP3基因在转基因玉米中的表达水平。改造后的基因命名为VIP3m基因,由生工生物工程(上海)股份有限公司合成,将基因VIP3、VIP3m分别构建到pUC57载体上,得到具有氯霉素抗性的质粒pUC57-VIP3和pUC57-VIP3m。基因VIP3m及其编码蛋白的序列分别如SEQ ID NO:1和2所示。
实施例2转VIP3m基因玉米的构建
1、植物转化载体p3301Ubi-VIP3和p3301Ubi-VIP3m的构建
将质粒pCAMBIA3301用HindIII和BamHI进行双酶切,35S启动子替换为玉米Ubiquitin启动子,构建得到改造的质粒pCAMBIA3301(图1)。用BamHI和SacI双酶切改造的质粒pCAMBIA3301、pUC57-VIP3和pUC57-VIP3m,37℃水浴锅中酶切1h,酶切体系如下:
Figure BDA0002543583700000041
酶切产物经琼脂糖胶电泳,对照Marker分别切取约2.3kb大小的VIP3(SEQ ID NO:5)和VIP3m片段,及约11kb大小的改造pCAMBIA3301载体序列,用天根生化科技(北京)有限公司胶回收试剂盒对核酸片段进行回收;然后,按照T4连接酶的使用说明将切胶回收的核酸片段与纯化回收的载体片段进行连接。连接反应结束,取5μL连接产物转化大肠杆菌Trans5α。挑取克隆菌斑于10mL含相应抗生素的LB液体培养基中,37℃摇床震荡过夜培养,次日,提质粒并定量。用BamHI和SacI双酶切质粒,经琼脂糖电泳验证载体p3301Ubi-VIP3(图2)、p3301Ubi-VIP3m(图3)构建的正确性。
2、农杆菌转化法获得转基因玉米植株
将载体p3301Ubi-Cry1Ab、p3301Ubi-Cry1Ab-l通过冻融法转化到农杆菌EHA105中,PCR进行鉴定。以新鲜剥离的1mm左右的玉米综31幼胚为材料,将幼胚置于侵染培养基中1h后,用侵染培养基清洗一次,再浸入添加100μM乙酰丁香酮的侵染培养基的农杆菌菌液中,并放置5分种。取出用灭菌滤纸吸干,置于共培养基上,在26℃黑暗条件下共培养3天,并设对照。幼胚洗涤去菌后,置于含1.5mg/L Bialaphos的筛选培养基上,开始筛选培养两周,然后转到含3mg/L Bialaphos筛选培养基上筛选培养,每三周继代一次,筛选培养至两个月,有一些愈伤生长状态良好,为抗性愈伤。将选出的抗性愈伤组织转接到诱导胚状体培养基上,3周即可出现胚状体。再转入到分化培养基上进行分化,培养条件为28℃,每日3000Lux光强,光照16小时,很快就会有再生小苗出现。再生的小植株长到3片叶时,可将幼苗移植到罐头瓶中,并在室内培养。待小苗长出新叶及根后,将幼苗从罐头瓶中取出,自来水冲净培养基,移栽于混有营养土和蛭石(1:3,体积比)的小花盆中。待玉米又长出2-3片新叶时,可将其移入大田或大花盆中,自交获得T1代种子。
本实施例中使用的侵染培养基、共培养培养基、再生培养基、生根培养基可参照ZL201710090814.2。
实施例3 VIP3和VIP3m在转基因玉米中的表达量检测
利用上海佑隆公司生产的VIP3蛋白ELISA检测试剂盒检测转基因玉米中的VIP3蛋白含量。称取约0.1g转基因玉米叶片,在液氮中研磨成粉末。加入1ml蛋白提取液(来自所述ELISA检测试剂盒)震荡混匀30min,使蛋白充分溶解在提取液中,离心取上清用于分析。每个酶标板孔中加入50ul酶联反应液,然后在不同的孔中分别加入不同浓度的VIP3标准蛋白、转基因玉米蛋白提取物,室温孵育1-2小时,用洗涤缓冲液洗涤3次,加入100ul反应底物后室温孵育10-30分钟,加入100ul终止缓冲液,用酶标仪测定在450nm下的吸光值,计算转基因玉米中VIP3蛋白含量。结果表明,转VIP3m基因玉米中的VIP3蛋白含量显著高于转VIP3基因的蛋白含量(表1)。

种植在温室田间的转基因玉米长至7-8叶期时,取幼嫩叶片放入培养皿中,每皿接5头初孵草地贪夜蛾幼虫。试验在相对湿度为70%–80%、温度为26–28℃、光照周期为16h:8h(L:D)的培养室里进行,每24h统计昆虫的死亡率,根据组织被取食消耗情况添加或更换相同来源的新组织,试验在相同条件下重复三次。结果表明,转空载体和VIP3基因玉米感草地贪夜蛾,而转VIP3m基因玉米高抗草地贪夜蛾,抗虫性明显提高(图4)。
实施例5 Cry1Ab-l和VIP3m蛋白的室内杀虫试验
1、蛋白表达纯化
对来自苏云金芽孢杆菌(Bacillus thuringiensis,Bt)的Cry1Ab蛋白(GenBankNo.X04698)的1155个氨基酸序列进行分析,选取前658个氨基酸残基作为新型杀虫蛋白,命名为Cry1Ab-l。根据玉米密码子偏好性对编码Cry1Ab-l的基因进行优化,G+C含量由原来的38.8%提高到63.7%,进一步提高Cry1Ab-l基因在转基因玉米中的表达水平。设计的Cry1Ab-l基因由生工生物工程(上海)股份有限公司合成。基因Cry1Ab-l及其编码蛋白的序列分别如SEQ ID NO:3和4所示。
将Cry1Ab-l和VIP3m基因分别构建到pET30a载体上,得到具有氯霉素抗性的质粒pET30-Cry1Ab-1和pET30-VIP3m。将质粒共同转入购自全式金公司的菌株Transetta(DE3)中,挑取单克隆,PCR扩增验证阳性菌斑。将检测阳性的菌斑接种于10mL的LB液体培养基中(含适宜抗生素),于37℃过夜振荡培养,得到种子液。
次日,按1:200的比例将种子液接种到200mL LB液体培养基中(含适宜抗生素),37℃,200rpm震荡培养至OD600为0.4-0.6,加入IPTG至终浓度0.5mM,16℃摇床,160rpm,震荡培养20h左右,诱导目的蛋白的表达。
收集200mL诱导的菌体,4℃5000rpm离心5min,弃上清液,加入10mL重悬液(25mMTris-HCl,150mM NaCl,15mM咪唑),加入10mg/mL的溶菌酶至终浓度为100μg/mL,振荡后于冰上放置10min,超声波破碎,每隔3s超声4s,300w,15-20min,使菌体充分破碎,破碎过程冰上操作。
4℃12000rpm离心15min,取上清,用0.45μm滤膜过滤。加入1mL混匀的50%的Ni-NTA树脂,室温下于摇床上轻微振荡90min,使目的蛋白充分结合到Ni-NTA树脂上。将结合有目的蛋白的Ni-NTA树脂装柱纯化。镍柱预先用70%乙醇平衡,之后用5倍镍柱体积的重悬液平衡。
低速向柱子中加入混匀好的蛋白上清和树脂的混合物,收集流出液,标记为L15。
用溶液I(25mM Tris-HCl,150mM NaCl,30mM咪唑)8mL洗涤,收集流出液,标记为L30。
用溶液II(25mM Tris-HCl,150mM NaCl,100mM咪唑)4mL洗涤,收集流出液,标记为L100。
用溶液III(25mM Tris-HCl,150mM NaCl,250mM咪唑)10mL洗涤,收集流出液,标记为L250。
以上纯化过程均在4℃环境中操作,并严格避免交叉污染。
纯化蛋白分别转入透析袋中,用透析液(25mM Tris-HCl,150mM NaCl)在4℃,转子搅拌下透析24h,每8h更换一次透析液。透析处理后,采用考马斯亮蓝蛋白定量试剂盒对纯化的L250蛋白进行定量。
2、室内虫试
在室内温度28±1℃、光周期(L:D)16h:8h、相对湿度70-80%的条件下,采用人工饲料混合法进行室内玉米螟、棉铃虫、草地贪夜蛾虫试,将纯化的蛋白分别以25μg/g的量添加到人工饲料中配成饲养饲料,将饲料均分到48孔细胞培养板中,以不添加蛋白的饲料作为阴性对照。取不同培养板分别在每孔接玉米螟、棉铃虫或草地贪夜蛾初孵幼虫一头,共接虫144头,7天后统计虫子死亡率。结果表明联合使用杀虫蛋白Cry1Ab-l和VIP3m对玉米螟、棉铃虫和草地贪夜蛾的杀虫效果比Cry1Ab-1和VIP3m明显提高(表2)。

实施例6转Cry1Ab-l和VIP3m基因玉米的构建及抗虫性鉴定
1、植物转化载体p3301Ubi-Cry1Ab-Ubi-VIP3的构建
PCR扩增质粒p3301Ubi-Cry1Ab1(图5)上的Ubiquitin-Cry1Ab-1-NOS表达框序列,表达框序列两端扩增时加上HindIII酶切位点。将质粒p3301Ubi-VIP3m(图3)用HindIII酶切,将Ubiquitin-Cry1Ab-1-NOS表达框插入到酶切的载体上,构建成质粒p3301UbiAbUbiVIP3(图6)。
2、转基因玉米的制备
按照实施例2中的方法将质粒p3301Ubi-Cry1Ab1和质粒p3301UbiAbUbiVIP3分别转化农杆菌,进一步转化玉米获得转基因玉米植株。
3、转Cry1Ab-l和VIP3m玉米抗虫性鉴定
种植在温室的转基因玉米长至7-8叶期时,取幼嫩叶片放入培养皿中,每皿分别接初孵玉米螟、棉铃虫、草地贪夜蛾幼虫。试验在相对湿度为70%–80%、温度为26–28℃、光照周期为16h:8h(L:D)的培养室里进行,每24h统计昆虫的死亡率,根据组织被取食消耗情况添加或更换相同来源的新组织,试验在相同条件下重复三次。结果表明,转Cry1Ab-1和VIP3m基因玉米高抗玉米螟、棉铃虫和草地贪夜蛾,抗虫性明显提高(表3)。
