Description
技术领域
本发明涉及生物技术领域,具体涉及PUB22基因在调控植物对虫害胁迫抗性中的应用。
背景技术
番茄(Solanum lycopersicum L.)是世界上最重要的经济蔬菜之一,也是目前设施栽培面积最大的蔬菜品种之一。随着设施蔬菜产业的迅速发展,番茄产量得到快速增长,但同时也给害虫提供了适宜生长繁殖的环境,各类植食性有害生物的危害不断加剧,造成了极大的经济损失(任顺祥等,《生物防治》,北京:中国农业出版社,2011)。其中棉铃虫(Helicoverpa armigera)的主要寄主为棉花、蔬菜等经济作物,蔬菜作物中以番茄受害最为严重。棉铃虫以幼虫为危害形态,取食番茄茎叶和果实,幼果内部被吃空后导致腐烂,最后造成早落,以致无法长成大果,降低产量;取食后的伤口也更易于病菌侵入,造成严重减产,已成为发展晚茬番茄生产的一个主要障碍因素。
长期以来,害虫的防治主要依赖于化学药剂,且药剂施用量大、施用次数多,以致害虫容易产生抗药性,导致防治困难,从而造成恶性循环。农药污染有悖于生态环境保护、且对人畜产生残留毒害。因此,探究番茄抵御棉铃虫的内在机制对于番茄生产及培育抗虫新品种具有重要意义。
经过长期的共同进化,植物和昆虫已经发展出复杂的适应机制。一般来说,植物能够识别食草或损伤相关的分子模式(HAMPs/DAMPs)触发胞内抗性响应,其中茉莉酸(JA)信号途径在防御昆虫中发挥了重要的作用。JA与异亮氨酸结合形成的衍生物茉莉酸-异亮氨酸(JA-Ile)作为JA信号途径中的活性物质被受体COI1识别,进而COI1与JAZ(JAZMONATEZIM-DOMAIN)作用,导致JA信号途径中的负调控因子JAZ降解,从而释放了与JAZ相互作用的转录因子,继而激活下游防御基因的表达(Chini Adeng等,“Redundancy and specificityin jasmonate signalling.”Curr Opin Plant Biol,2016,33,147–156;Sheard LB等,“Jasmonate perception by inositol-phosphate-potentiated COI1-JAZ co-receptor.”Nature,2010,468,400–405)。然而,除了传统的JA信号通路外,番茄中JAZ是否可能被其他蛋白所靶向降解却鲜有研究报道。
植物蛋白质的稳定性和活性与泛素-蛋白酶体系统(ubiquitin-proteasomesystem,UPS)密切相关,该系统通过特异靶标目的蛋白,调控其活性与降解,进而影响植物体内多种生理过程,如植物细胞分裂、对生物胁迫和非生物胁迫的响应等(Zhang Z等,“Roles of ubiquitination-mediated protein degradation in plant responses toabiotic stresses.”Environ.Exp.Bot.,2015,114,92-103)。U-box蛋白作为一种重要的E3泛素连接酶,其在植物抗逆反应中的功能具有很大的研究价值且取得一定进展,包括发育过程中的细胞增殖、对干旱的适应以及病原体攻击时的免疫反应,但对于其在虫害胁迫中的作用鲜有报道。
目前,已鉴定出番茄PUB(Plant U-Box)基因家族(Bhaskar S and Joemar T,“Genome-wide analysis of the U-box E3 ubiquitin ligase enzyme gene family intomato”,Scientific Reports,2020,10,9581),但是各个PUB基因在番茄生长发育及胁迫响应中的作用还鲜有研究报道。
发明内容
本发明的目的在于提供一种可提高植物对虫害胁迫尤其是棉铃虫抗性的基因,为培育抗虫害的植物品种提供依据。
为实现上述目的,本发明采用如下技术方案:
本发明提供了PUB22基因在调控植物对虫害胁迫抗性中的应用,所述PUB22基因的蛋白编码区的核苷酸序列如SEQ ID NO.1所示或与SEQ ID NO.1所示序列具有至少70%同源性且编码的蛋白在功能上等价。
进一步的,所述PUB22基因功能缺失,减弱植株对虫害胁迫的抗性。证明了PUB22基因在提高植物虫害胁迫抗性中的用途。
进一步的,所述植物为番茄。
进一步的,所述虫害为棉铃虫。
进一步的,所述PUB22基因通过促进植物抗性激素合成,进而提高其对虫害胁迫的抗性。
所述植物抗性激素为茉莉酸。
本发明通过基因编辑技术和组培技术获得PUB22基因功能缺失突变体,与野生型植株相比,在棉铃虫胁迫条件下突变体中茉莉酸及茉莉酸-异亮氨酸衍生物的含量显著下降,因此,PUB22基因正调控植物对棉铃虫的抗性。
具体的,所述PUB22基因敲除后,降低植株体内茉莉酸及茉莉酸-异亮氨酸衍生物的含量,从而减弱植物对虫害胁迫的抗性。
进一步机理研究表明,PUB22基因编码的蛋白质与JAZ蛋白互作,调控茉莉酸信号途径。JAZ蛋白是茉莉酸信号通路中的负调控因子。
进一步的,所述PUB22基因编码的蛋白质的氨基酸序列如SEQ ID NO.2所示。JAZ蛋白编码区的核苷酸序列如SEQ ID NO.3所示,其氨基酸序列如SEQ ID NO.4所示。
本发明具有的有益效果:
本发明首次公开PUB22基因在调控植物对虫害胁迫尤其是棉铃虫抗性方面的用途,通过CRISPR/Cas9基因编辑技术缺失PUB22基因功能,可显著减弱植物对棉铃虫的抗性,证明了PUB22基因在提高植物虫害胁迫抗性中的用途,可将其应用到抗虫害胁迫植株品种的培育中。本发明为植物分子抗逆遗传育种、植物胁迫耐受的遗传改造等方面提供更多的基因资源和新思路。

下述实施例中采用的番茄品种为番茄常规品种Condine Red。
实施例1番茄SlPUB22缺失突变体植株的制备与鉴定
1、含特异sgRNA的CRISPR/Cas9载体的构建
首先,在SGN网站(https://solgenomics.net/)上找到番茄SlPUB22基因的DNA全长序列如SEQ ID NO.6所示,分析其蛋白编码区的核苷酸序列如SEQ ID NO.1所示,其蛋白编码区长度为3024bp;该SlPUB22基因编码的蛋白为含有U-box结构域的E3泛素连接酶,由1007个氨基酸组成,其序列如SEQ ID NO.2所示。
将SlPUB22基因的DNA全长序列输入CRISPR2网站(http://crispr.hzau.edu.cn/CRISPR2)网站,找出on score得分高,且GC含量>40%,位于蛋白编码区的一段PAM结构前的20bp碱基序列作为特异性靶向基因蛋白编码区的sgRNA,如SEQ ID NO.5所示。
以tRNA-sgRNA-gRNA scaffold为模板扩增出含有上述所选特异性sgRNA序列的片段,且其两端具有BsaⅠ限制性内切酶的酶切位点,将上述片段插入到pHEE401载体的BsaⅠ位点并转化大肠杆菌DH5α感受态,挑单克隆进行测序,测序正确的质粒电击转化GV3101农杆菌感受态,获得可用于构建CRISPR/Cas9基因编辑材料的农杆菌菌株。
2、SlPUB22基因突变体材料的制备与鉴定
番茄种子经消毒后播种于1/2MS培养基中,黑暗培养至种子发芽后,移至光下培养。待子叶长出后,将子叶切下置于看护培养基中,黑暗培养12-24h。将准备好的用于构建CRISPR/Cas9基因编辑材料的农杆菌培养至对数期,离心去上清,加入MS0.2重悬浮,用于侵染子叶外植体,暗下侵染2.5min,吸干子叶外植体表面剩余菌液后置于看护培养基上,黑暗下共培养两天。共培养后,子叶外植体转移至2Z培养基中诱导愈伤组织,2-3周后转入0.2Z培养基中诱导发芽,每2周转入新的0.2Z培养基,直至长出小苗后,转入R培养基诱导生根,约2-3周后待根系发育良好,将其转移至基质中并进行保湿,成活后对T0代基因编辑材料进行验证。
取少量T0代植株叶片提取基因组DNA并以其为模板,进行PCR扩增含有sgRNA的DNA片段,然后对PCR产物进行测序比对,选取sgRNA序列发生碱基突变、缺失或插入的植株进行自交繁种,获得T0代种子。
验证引物如下:
验证前引物:GCTCATTTGTATTGCTAGAGCTGTT(SEQ ID NO.7);
验证后引物:ATGCTTTCTTCAGGTTTGCGTG(SEQ ID NO.8)。
将T0代的种子播种后得到T1代植株,利用上述方法检测T1代植株的sgRNA序列碱基编辑情况及Cas9的存在与否,选取不含Cas9,但sgRNA发生变异的植株进行繁种,自交获得不含外源基因Cas9,且稳定遗传的T1代纯合突变体植株1个株系,其基因编辑位点如图1所示,pub22突变体比野生型多1个碱基。
对上述株系进一步自交繁种,种子播种后获得不含外源基因Cas9,且sgRNA发生变异的稳定遗传的T2代植株。
以下实施例均以T2代纯合株系作为材料进行实验。
实施例2番茄SlPUB22基因抗棉铃虫表型的鉴定
棉铃虫采用河南省济源白云实业有限公司购买的3龄棉铃虫,挑选大小一致的棉铃虫至24孔板中,进行饥饿一晚的处理。
待番茄幼苗长至六叶一心时,选取从上往下第2-4节位叶片,称取相同质量叶片(1±0.05g)置于装有1%琼脂的培养皿中,以防止离体叶片失水,并对接虫前番茄叶片进行拍照记录。然后将两头经饥饿处理的棉铃虫接种到一个培养皿的番茄叶片上,盖上培养皿盖并用皮筋固定,防止棉铃虫离开培养皿。弱光下接虫处理3天后,检测棉铃虫重量,然后用70%甲醇浸泡棉铃虫至其不再活动,按体型大小排列后进行拍照记录。对接虫后番茄叶片也相应进行拍照记录及称重。
结果如图2和图3所示,饲喂pub22突变体叶片的棉铃虫相比饲喂野生型叶片的棉铃虫体型较大、重量较重,且pub22突变体叶片经接虫处理后受到的损失相比野生型叶片更重,受损后叶片重量较轻,说明SlPUB22基因正调控番茄的棉铃虫抗性。
实施例3番茄SlPUB22基因对抗性激素JA和JA-Ile的影响
待番茄幼苗长至六叶一心时,选取从上往下第3-4节位叶片进行W+OS模拟棉铃虫取食处理,并于0、1h采集叶片样品分析JA、JA-Ile激素水平,每个时间点设置4个重复。
W+OS模拟棉铃虫取食处理方式如下:用止血钳在小叶主叶脉两侧叶面各夹一次制造机械伤,然后在创伤处涂抹稀释五倍的棉铃虫口器分泌物。
棉铃虫口器分泌物的获取方式为:棉铃虫饥饿12h后,饲喂番茄叶片,12h后吸取棉铃虫口器分泌物为原液。
JA、JA-Ile激素测定方式为:称取0.1g番茄叶片,经液氮研磨后,加入1ml色谱级乙酸乙酯,避光加入JA、JA-Ile激素内标,涡旋混匀后,包上一层锡箔纸以避光,置于4℃摇床过夜,摇床频率为150rpm。4℃、12000rpm离心10min后,吸取850μl上清于新的10ml管中,4℃避光保存。剩下的沉淀中再加入1ml色谱级乙酸乙酯,重悬后置于4℃摇床震荡1h,再次4℃、12000rpm离心10min后,吸取900μl上清。合并两次上清,利用氮气吹干。加入500μl 70%色谱级甲醇,涡旋30s,转移液体至1.5ml管中,瞬离后吸取200μl上清至进样瓶内衬中,利用高效液相色谱串联质谱法测定(Varian320-MSLC/MS,Agilent Technologies,Amstelveen,Netherlands)。
结果如图4所示,W+OS处理后1h,pub22突变体植株的JA、JA-Ile含量显著低于野生型植株,说明敲除SlPUB22基因降低了番茄植株在棉铃虫取食后的JA、JA-Ile含量,从而减弱了番茄的棉铃虫抗性。
实施例4番茄SlPUB22蛋白与SlJAZ1蛋白互作的酵母双杂交验证
首先我们构建了含SlPUB22基因的pGBKT7-BD载体并转化酵母,但是转化了全长SlPUB22基因的酵母不能正常生长,猜测全长SlPUB22基因的表达产物对酵母有毒性。因此,我们选取了预测的蛋白互作区域,即ARM结构域,构建了含SlPUB22基因ARM结构域的pGBKT7-BD载体。
以番茄cDNA为模板,利用前引物PUB22ARM-BD-F为:atggccatggaggccgaattcATGATCACCATTGCGTCTCTAAAA(SEQ ID NO.9),后引物PUB22ARM-BD-R为:ctagttatgcggccgctgcagCAAGTGAGATAGAACTTTAGCAGCTAAA(SEQ ID NO.10)进行PCR扩增,得到SlPUB22基因ARM结构域的CDS序列。利用EcoRⅠ和PstⅠ限制性内切酶对pGBKT7-BD载体进行双酶切,将酶切载体与PCR产物进行同源重组并转化大肠杆菌DH5α感受态。
构建含SlJAZ1基因的pGADT7-AD载体:
方法同上,酶切位点为EcoRⅠ和XhoⅠ,所用前引物SlJAZ1-AD-F为:gccatggaggccagtgaattcATGGCTTCATCGGAGATTGTGG(SEQ ID NO.11),后引物SlJAZ1-AD-R为:acgattcatctgcagctcgagCTAGTATTGCTCAGTTTTCACTGCAA(SEQ ID NO.12)。
将测序正确的质粒以下列组合使用酵母转化试剂盒(YeastmakerTM YeastTransformation System 2,Takara Bio,Japan)共转化Y2H Gold酵母菌株:PUB22ARM-BD+SlJAZ1-AD、PUB22ARM-BD+AD、BD+SlJAZ1-AD、BD+AD。转化方法详见试剂盒说明书。
将成功转化的酵母利用SD/-Leu/-Trp液体培养基进行筛选扩繁,离心收集并用0.9%NaCl重悬浮并调整浓度至OD600=0.2,再进行梯度稀释至0.02、0.002后,吸取10μl菌液分别在SD/-Leu/-Trp和SD/-Leu/-Trp/-Ade/-His固体培养基上点斑,30℃倒置培养3-5天后拍照记录实验结果。
结果如图5所示,PUB22ARM-BD+SlJAZ1-AD、PUB22ARM-BD+AD、BD+SlJAZ1-AD、BD+AD在SD/-Leu/-Trp培养基上正常生长,说明载体均成功转化酵母菌株,而仅PUB22ARM-BD+SlJAZ1-AD在SD/-Leu/-Trp/-Ade/-His培养基上生长,其余对照组均未生长,说明PUB22ARM与SlJAZ1蛋白在酵母中存在互作,SlJAZ1蛋白可能作为PUB22的靶向蛋白被其降解,探索了番茄中JAZ蛋白的降解机制。
