Abstract
本发明涉及一种控制亚洲玉米螟害虫的方法,属于害虫控制领域。本发明通过测试发现WBY‑1蛋白对亚洲玉米螟有较好的杀虫活性,为防治亚洲玉米螟害虫提供了新的手段。
Description
技术领域
本发明涉及一种控制亚洲玉米螟害虫的方法,属于害虫控制领域。
背景技术
鳞翅目昆虫(Lepidoptera)属有翅亚纲下的一目。全世界已知的种类达到20万种,中国已知的约8000余种,绝大多数种类的幼虫为害各类植物。棉铃虫、菜粉蝶、小菜蛾、豆荚螟、玉米螟等害虫均是为害十分广泛的农田害虫,为农业的正常生产造成了极大的障碍,带来了很高的防治成本。
亚洲玉米螟(学名:Ostrinia furnacalis)属鳞翅目螟蛾科秆野螟属,是我国玉米等作物的重要害虫,从黑龙江到海南各玉米产区均有发生危害。亚洲玉米螟饮食多样化,除了玉米以外还可对高粱、谷子、马铃薯、向日葵、工业大麻、蚕豆、菜豆等作物造成危害。亚洲玉米螟为害玉米植株地上的各个部位,使受害部分丧失功能,降低籽粒产量。在玉米心叶期,初孵幼虫大多爬入心叶内,群聚取食心叶叶肉,留下白色薄膜状表皮,呈花叶状;2、3龄幼虫大多爬入心叶内潜藏为害,心叶展开后,出现整齐的排孔;此后,陆续蛀入茎秆继续为害,蛀孔口常堆有大量粪渣;雄穗被蛀,常易折断,影响授粉;苞叶、花丝被蛀食,会造成缺粒和秕粒;茎秆、穗柄、穗轴被蛀食后,形成隧道,破坏植株内水分、养分的输送,使茎秆倒折率增加,籽粒产量下降。
除了传统物理和化学防治方法外,利用杀虫蛋白开发生物工程菌或转基因植物也能够达到防治害虫的效果,且防治成本更低、环境更友好。因此找到每种害虫对应的杀虫蛋白就至关重要。
CN202311033251.5专利中的WBY-1、WBY-7蛋白是利用人工智能技术辅助生成的新型杀虫蛋白,它们对草地贪夜蛾均有较高的杀虫活性。但是,这些蛋白对其他一些害虫是否也有活性却并不知道。测试这些蛋白的杀虫谱能够为特定害虫提供新的防治手段。
发明内容
为了解决上述问题,本发明采用如下技术方案:
本发明提供一种控制亚洲玉米螟害虫的方法,其特征在于,包括将亚洲玉米螟害虫至少与WBY-1蛋白接触。
在一些实施方案中,所述WBY-1蛋白存在于至少产生所述WBY-1蛋白的宿主细胞中,所述亚洲玉米螟害虫通过摄食所述宿主细胞至少与所述WBY-1蛋白接触。
在一些实施方案中,所述WBY-1蛋白存在于至少产生所述WBY-1蛋白的细菌或转基因植物中,所述亚洲玉米螟害虫通过摄食所述细菌或所述转基因植物的组织至少与所述WBY-1蛋白接触,接触后所述亚洲玉米螟害虫生长受到抑制和/或导致死亡,以实现对亚洲玉米螟危害植物的控制。
在一些实施方案中,所述转基因植物为玉米、高粱、谷子、马铃薯、向日葵、工业大麻、蚕豆或菜豆。
在一些实施方案中,所述转基因植物的组织为根、叶片、茎秆、果实、雄穗、雌穗、花药或花丝。
在一些实施方案中,所述WBY-1蛋白氨基酸序列如SEQ ID NO. 3所示。
在一些实施方案中,所述WBY-1蛋白在细菌中的核苷酸序列如SEQ ID NO. 7所示。
在一些实施方案中,所述转基因植物还包括至少一种不同于编码所述WBY-1蛋白的核苷酸的第二种核苷酸。
在一些实施方案中,所述第二种核苷酸编码Cry类杀虫蛋白质、Vip类杀虫蛋白质、蛋白酶抑制剂、凝集素、α-淀粉酶或过氧化物酶。
在一些实施方案中,所述第二种核苷酸为抑制目标昆虫害虫中重要基因的dsRNA。
本发明还提供WBY-1蛋白质控制亚洲玉米螟害虫的用途。
本发明还提供一种产生控制亚洲玉米螟害虫的植物的方法,其特征在于,包括向所述植物的基因组中引入编码WBY-1蛋白的多核苷酸序列。
本发明还提供一种产生控制亚洲玉米螟害虫的植物种子的方法,其特征在于,包括将由上述方法获得的第一植株与第二植株杂交,从而产生含有编码WBY-1蛋白的多核苷酸序列的种子。
本发明还提供一种培养控制亚洲玉米螟害虫的植物的方法,其特征在于,包括:种植至少一粒植物种子,所述植物种子的基因组中包括编码WBY-1蛋白的多核苷酸序列;使所述植物种子长成植株;使所述植株在人工接种亚洲玉米螟害虫和/或亚洲玉米螟害虫自然发生危害的条件下生长,收获与其他不具有编码WBY-1蛋白的多核苷酸序列的植株相比具有减弱的植物损伤和/或具有增加的植物产量的植株。
本发明的有益效果在于:本发明通过测试WBY-1、WBY-7蛋白对桃蛀螟、东方粘虫、亚洲玉米螟、棉铃虫、小地老虎、斜纹夜蛾、大豆卷叶螟这几种昆虫的杀虫活性,明确了这蛋白的杀虫谱,并发现WBY-1蛋白对亚洲玉米螟有较好的杀虫活性,为亚洲玉米螟害虫防治提供了新的手段。

实施例1蛋白的制备合成
使用蛋白表达实验系统合成这些蛋白实物,并测试它们对几种鳞翅目害虫的杀虫效果。
首先根据氨基酸序列设计编码该序列的核酸序列(在如下在线工具中开展http://www.friendbio.com/codon.html),其中密码子设置为大肠杆菌(K12菌株)偏爱性,并避免XhoI和HindIII酶切位点。WBY-1、WBY-7蛋白的氨基酸序列分别如SEQ ID NO. 1、SEQID NO. 2所示,获得的编码蛋白的核酸序列如SEQ ID NO. 3、SEQ ID NO. 4所示。
人工合成上述序列的核酸分子,克隆到载体pET28a表达载体中限制性内切酶XhoI和HindIII的位点之间,获得蛋白表达载体。将该载体转入大肠杆菌BL21细胞系,并进行蛋白表达。具体步骤如下:
单个菌落接种到0.5 mL LB液体培养基,在37℃下培养4 h至培养基浑浊,取100 μL菌液加入 IPTG(Isopropyl-β-D-thiogalactoside)至终浓度为0.8 mM,同时取100 μL菌液作为阴性对照,继续培养4 h,在100 μL菌液中加入25 μL上样缓冲液制样电泳,根据阴性对照和加入IPTG诱导的结果对比,判断是否有表达。有表达的取剩余20 μL,接种到2 mL LB液体培养基中37℃下培养12-16 h作为种子液,种子液再接种到250 mL LB液体培养基至OD600=0.5-0.6,然后加IPTG(Isopropyl-β-D-thiogalactoside)至浓度为0.8 mM,并继续在同样的条件下培养4小时。 培养液经过5000 g离心10分钟沉淀大肠杆菌细胞,然后弃上清收集沉淀。沉淀中加30 mL 20mM Tris-50mM NaCl缓冲液,超声破碎。离心后检测上清液是否含有重组蛋白,并进行定量。
实施例2杀虫效果测试
进一步将上述实施例获得的重组蛋白进行杀虫活性测试。具体为:
采用表面涂抹方法进行生物测定,先在24孔板中先加入约1 mL未凝固的人工饲料(约1 g),轻微晃动使饲料铺满孔板底部,待饲料凝固后,再加入不同浓度的蛋白溶液(20 μL/孔),加入后轻轻晃动使药液均匀地平铺在饲料表面上,在通风橱内自然风干1 h。实验设置6个梯度浓度(0.001、0.01、0.1、0.5、1、2 μg/cm2)和一个空白对照(缓冲液),每个处理接24头人工饲养的目标昆虫初孵幼虫(孵化时间为2~12 h),设3次重复,放置在温度26±2℃,光周期14:10(L:D)h,相对湿度50-70%的养虫室培养,7天后调查死亡率。以用毛笔轻触幼虫尾部,幼虫不动视为死亡,幼虫未发育2龄的也视为死亡。
根据如下公式计算死亡率和校正死亡率,并利用graphpad计算LC50值。
(公式1)
(公式2)
测试结果表明,虽然WBY-1和WBY-7对东方粘虫和草地贪夜蛾均具有较好的杀虫活性,但是WBY-1对亚洲玉米螟的LC50可以达到0.84,杀虫活性较佳;而WBY-7对亚洲玉米螟的LC50高达1.29,杀虫活性不理想(见表1)。因此,WBY-1是用于防治亚洲玉米螟害虫的较优选择(生测结果照片见图1)。
