Description
技术领域
本发明属于生物技术领域,更具体地,本发明涉及葡萄溃疡病抗性相关蛋白VvRHIP1及其编码基因与应用。
背景技术
葡萄(Vitis vinifera L.)集鲜食与酿酒于一身,经济价值高。由葡萄座腔病菌引起的葡萄溃疡病(Botryosphaeria dieback)是葡萄生产上最重要的枝干病害之一,在葡萄主产区分布广泛,严重影响葡萄的产量和品质,每年均造成巨大的经济损失。该类型病原真菌主可通过自然孔口或修剪伤口侵入寄主,引起枝干溃疡、果梗干枯、果实干缩或掉粒以及树势减弱等症状,更严重的会引起整株枯死。至今,在我国已分离获得6种葡萄座腔菌科真菌(Botryosphaeriaceae)可引起葡萄溃疡病,其中优势种群是可可毛色二孢菌(Lasiodiplodia theobromae)和葡萄座腔菌(Botryosphaeria dothidea),而致病力最强的是可可毛色二孢菌。目前化学农药是防治该病害普遍应用的措施,但迄今为止,尚未获得低毒环保并能够高效防治该病害的农药。而长期农药的使用,不仅会加重农户的经济负担,还造成了环境污染。防控植物病害最有效的手段应该是从提高植物自身的抗病力出发,因此植物新型抗病基因的挖掘和利用,对植物的抗病遗传育种具有重要意义。
葡萄糖、果糖和蔗糖等糖类化合物可同时作为代谢物和信号分子调控植物的生长发育和免疫应答等代谢过程。在拟南芥中,葡萄糖主要通过(1)G蛋白信号转导调节因子1(AtRGS1)介导的质膜G蛋白偶联途径;(2)己糖激酶1(AtHXK1)途径;(3)糖酵解依赖的SNF相关激霉1/雷帕霉素靶点(SnRK1/TOR)三条途径来感应并向下游传递。D-葡萄糖和激发子鞭毛蛋白flg22处理拟南芥后,引起AtRGS1内吞,从而激活G蛋白介导的糖信号转导。并且,为AtRGS1和AtHXK1提供物理支架的AtRHIP1在葡萄糖信号通路中也起着关键作用。据报道,葡萄糖传感器在植物-病原体互作过程中通过糖信号通路调节植物免疫反应。而葡萄糖信号通路组分(VvRHIP1是葡萄中AtRHIP1的同源类似物)是否参与葡萄溃疡病菌的免疫调控未见报道。

实施例3、葡萄溃疡病抗性相关基因VvRHIP1的转基因功能验证
1.超表达VvRHIP1转基因烟草的获得
超表达载体构建:用引物VvRHIP1-GF:5’-CCAAGCTTATGGCGGAGGCGACGCCGTCGTCAG-3’和VvRHIP1-GR:5’-GGACTAGTAACAGGAACCCCTAATTCAGAAATC-3’进行配对,以T-VvRHIP1为模板,进行PCR扩增,回收小片段插入到

采用叶盘法转化方法,本生烟草种子用无菌水冲洗2遍,75%乙醇漂洗30秒后,随后用2.5%次氯酸钠浸泡5-10min,无菌水冲洗5次并用无菌滤纸吸干水分,置于1/2MS培养基培养4-5周。将无菌烟草叶片切成约0.5cm×0.5cm大小,置于转Super-VvRHIP1-GFP农杆菌的悬浮液中,浸泡8-10min,并不时晃动。取出后,用无菌滤纸吸去多余菌液,将叶片转到含BAP 1.0mg/L的MS固体培养基上于26℃培养3天。将共培养后的烟草叶盘用含特美丁250mg/L的MS液体培养基清洗后,置于含BAP 1.0mg/L、潮霉素30mg/L、特美丁250mg/L的MS固体筛选培养基上,26℃下培养。不定芽长到约1-2cm时,切下并转移到含潮霉素30mg/L、特美丁250mg/L的1/2MS生根培养基,生根培养3-4周,将小苗移至温室培养。2-3月后,收获该转基因苗收种为T1代种子,经潮霉素30mg/L筛选,获得纯和T2苗用于后续实验。
取转基因VvRHIP1-GFP的T2代烟草叶片,经液氮研磨后,采用多糖多酚/复杂植物RNA快速提取试剂盒(北京艾德莱生物科技有限公司)提取样品总RNA,利用SuperscriptⅢ反转录试剂盒(Invitrogen公司)反转录合成cDNA。设计特异性引物:上游引物VvRHIP1-qF:5’-CACTGGAAGTCAACTCAAG-3’;下游引物VvRHIP1-qR:5’-GATGTCATAGAAGCAACCTC-3’。内参基因NbEF1a引物序列为:NbEF1a-qF:5’-AAGGTCCAGTATGCCTGGGTGCTTGAC-3’;下游引物NbEF1a-qR:5’-AAGAATTCACAGGGACAGTTCCAATACCA-3’。反应体系为:0.5μL反转录产物,引物3.5μL(0.5μM),7μL 2×SYBR green,加水至总体积14μL。参照TaKaRa说明书,采用SYBRGreen I染料法进行荧光定量PCR,反应在ABI7500 Real-time PCR检测系统上进行。反应程序为:95℃预变性3min,进入95℃30s,60℃30s,72℃30s共40个循环,设置3个生物学重复。根据实时荧光定量PCR得到的Ct值以及标准曲线,采用2-△△Ct法分析数据,以野生型本生烟草做对照,计算VvRHIP1基因的相对转录水平。
结果如图2所示,VvRHIP1超表达烟草(OV-R3,OV-R16,OV-R25)株系中,VvRHIP1的表达量显著提高,是对照的150-200倍。
取转基因VvRHIP1-GFP的T2代烟草叶片,经液氮研磨后,用蛋白提取试剂盒将水稻叶片于液氮中充分研磨后,加入150L蛋白质抽提缓冲液[150mM NaCl,0.5%Triton X-100,50mM Tris-HCl(pH=7.5),蛋白酶抑制剂],冰上放置30min后4℃12000g离心10min,吸取上清于新管中,液氮速冻-80℃保存。上样前加入5×SDS的上样缓冲液煮沸5min,以使蛋白充分变性。SDS-PAGE电泳后,采用电泳印迹法进行将蛋白转PVDF膜;5℅脱脂牛奶封闭过夜;Anti-GFP一抗孵育4-6小时,TBST缓冲液漂洗膜后再浸洗三次,每次5-10min;加入二抗孵育1小时后,用HRP显色化学发光检测参考康为世纪的说明书。
结果如图3所示,VvRHIP1超表达烟草(OV-R3,OV-R16,OV-R25)株系中,都检测到VvRHIP蛋白的表达。
2.超表达VvRHIP1转基因烟草对可可毛色二孢菌菌株CSS-01s的抗性分析
将可可毛色二孢菌株CSS-01s转至PDA培养基上,于26℃培养2-3周产孢,调整孢子数目为1×106个/ml,以0.02%的silwet水溶液模拟接种作为对照。取生长6周的转基因VvRHIP1-GFP的T2代烟草叶片,将孢子悬浮液滴加到烟草叶片上,接种后的枝条置于26℃、12小时光照12小时黑暗、相对湿度为90%的接种室中培养,4-5天统计病斑长度,并拍照。于接种0和12小时,取接种叶片,液氮中速冻,-80℃冰箱保存备用。叶片经液氮研磨后,采用多糖多酚/复杂植物RNA快速提取试剂盒(北京艾德莱生物科技有限公司)提取样品总RNA,利用SuperscriptⅢ反转录试剂盒(Invitrogen公司)反转录合成cDNA。对防卫Marker基因(NbPR1和NbLOX)进行检测,设计特异性引物:上游引物NbPR1-qF:5’-CCGCCTTCCCTCAACTCAAC-3’,下游引物NbPR1-qR:5’-GCACAACCAAGACGTACTGAG-3’;上游引物NbLOX-qF:5’-AAAACCTATGCCTCAAGAAC-3’,下游引物NbLOX-qR:5’-ACTGCTGCATAGGCTTTGG-3’。内参基因VvEF1引物序列为:NbEF1a-qF:5’-AAGGTCCAGTATGCCTGGGTGCTTGAC-3’;下游引物NbEF1a-qR:5’-AAGAATTCACAGGGACAGTTCCAATACCA-3’。反应体系为:0.5μL反转录产物,引物3.5μL(0.5μM),7μL 2×SYBR green,加水至总体积14μL。参照TaKaRa说明书,采用SYBRGreen I染料法进行荧光定量PCR,反应在ABI7500 Real-time PCR检测系统上进行。反应程序为:95℃预变性3min,进入95℃30s,60℃30s,72℃30s共40个循环,设置3个生物学重复。根据实时荧光定量PCR得到的Ct值以及标准曲线,采用2-△△Ct法分析数据,计算基因的相对转录水平。
可可毛色二孢菌株CSS-01s接种VvRHIP1基因超表达株系6天后,我们对发病结果进行了统计,结果如图4A和4B所示。从图中看出,数值经显著性分析证明,VvRHIP1超表达烟草(OV-R3,OV-R16,OV-R25)三个超表达植株病斑长度比对照要小,发病情况要比野生型对照轻。
此外,通过荧光定量PCR分析了接种前后超表达植株中防卫相关基因的表达情况,结果如图5A和5B所示。接菌12h后,野生型中,NbPR1和NbLOX基因的表达较0h都有了一定程度的诱导;而在VvRHIP1超表达烟草(OV-R3,OV-R16,OV-R25)三个超表达植株植株中的诱导倍数要比野生型要大,说明VvRHIP1基因的超表达也影响(提高)了防卫相关基因NbPR1和NbLOX的表达。
3.激发子处理超表达VvRHIP1转基因烟草
为了进一步明确VvRHIP1基因是否在植物的防卫反应中发挥作用,用激发子鞭毛蛋白flg22对生长10天的转基因幼苗进行处理,于处理0和12小时,取接种叶片,液氮中速冻,-80℃冰箱保存备用。叶片经液氮研磨后,采用多糖多酚/复杂植物RNA快速提取试剂盒(北京艾德莱生物科技有限公司)提取样品总RNA,利用SuperscriptⅢ反转录试剂盒(Invitrogen公司)反转录合成cDNA。对防卫Marker基因(NbPR1和NbLOX)进行检测,设计特异性引物:上游引物NbAcre31-qF:5’-AATTCGGCCATCGTGATCTTGGTC-3’,下游引物NbAcre31-qR:5’-GAGAAACTGGGATTGCCTGAAGGA-3’;上游引物NbGras2-qF:5’-TACCTAGCACCAAGCAGATGCAGA-3’,下游引物NbGras2-qR:5’-TCATGAGGCGTTACTCGGAGCATT-3’;上游引物NbPti5-qF:5’-CCTCCAAGTTTGAGCTCGGATAGT-3’,下游引物NbGras2-qR:5’-CCAAGAAATTCTCCATGCACTCTGTC-3。内参基因VvEF1a引物序列为:NbEF1a-qF:5’-AAGGTCCAGTATGCCTGGGTGCTTGAC-3’;下游引物NbEF1a-qR:5’-AAGAATTCACAGGGACAGTTCCAATACCA-3’。反应体系为:0.5μL反转录产物,引物3.5μL(0.5μM),7μL 2×SYBR green,加水至总体积14μL。参照TaKaRa说明书,采用SYBR Green I染料法进行荧光定量PCR,反应在ABI7500 Real-time PCR检测系统上进行。反应程序为:95℃预变性3min,进入95℃30s,60℃30s,72℃30s共40个循环,设置3个生物学重复。根据实时荧光定量PCR得到的Ct值以及标准曲线,采用2-△△Ct法分析数据,计算基因的相对转录水平。通过qRT-PCR分析该基因的表达特性。结果图6显示,flg22处理12h后,野生型中,NbAcre3、NbGras2和NbPti5基因的表达较0h都有了一定程度的诱导;而在VvRHIP1超表达烟草(OV-R3,OV-R16,OV-R25)三个超表达植株植株中的诱导倍数要比野生型要大,说明VvRHIP1基因的超表达也影响(提高)了防卫相关基因NbAcre3、NbGras2和NbPti5的表达。
