Description
技术领域
本发明涉及葡萄果实成熟相关基因VvNAC及其应用,属于植物基因工程技术领域。
背景技术
葡萄是一种多年生果树,在世界范围内被广泛栽培利用,主要用于鲜食、制汁、制干和酿酒等,可以创造巨大经济价值。葡萄除味道可口之外,还富含丰富的维生素、矿物质和类黄酮等有益物质而具有保健功能。葡萄中的白藜芦醇具有抗癌、抗氧化和抗炎等功能,对人的健康有益,并且白藜芦醇还是一种植保素,可以在环境胁迫和病原菌入侵过程中由植物自身合成。现在越来越多的人参与到葡萄的研究当中,已经证实葡萄中的白藜芦醇不仅能够提高葡萄对各种胁迫的抗性,而且对人体保健如降血压、抑制血小板聚集防心血管疾病,以及抗氧化、抗肿瘤具有特殊功效。这些研究极大的丰富了葡萄栽培及营养保健的研究内容,促进了葡萄产业的发展。
根据果实在成熟过程中是否有呼吸峰的出现,将果实分为呼吸跃变型和非呼吸跃变型2种类型。迄今,对于跃变型果实成熟的调节与信号转导途径方面的研究已经上取得很大进展,尤其是在番茄上,通过大量的成熟缺陷突变体的研究获得了大量信息。对这些成熟缺陷突变体的研究在基因水平上证明了乙烯是跃变型果实成熟的最基本的信号物质。与这类跃变型果实相比,对非跃变型果实成熟的分子调控机制更是缺乏了解。葡萄作为非跃变型果实,一般认为它的成熟是由ABA调控的,而乙烯只起很小的作用。到目前为止,葡萄果实成熟的分子机制还不清楚。

葡萄果实成熟相关基因VvNAC及重组表达载体的应用的实施例1
1、抗性草莓植株的获得
将植物表达载体pCAMBIA2300-VvNAC以及不含VvNAC基因的空载体转化入农杆菌中。将两组农杆菌菌液于超低温冰箱取出后,在冰上溶化,取200μL接种于液体LB培养基中(含60mg·L-1Kan和60mg·L-1Gent),28℃180rpm培养20h后取30μL该菌液接种于20mL液体LB培养基中,相同条件下,进行二次活化,培养20h左右至菌液浑浊。将菌液转移到灭菌的50mL离心管中,6000rpm 8min,去上清,再用液体MS培养基(含200μMAS和3%的蔗糖)重悬菌液,28℃、180rpm培养3-4h,在紫外可见分光光度计上检测菌液浓度,可用重悬液稀释,使菌液浓度达到试验所确定的最佳浓度(OD600=0.1-0.2),备用。
选取饱满的草莓种子,用70%的乙醇消毒10s,再用有效氯1%的次氯酸钠溶液消毒15min,用无菌水冲洗干净,置于MS培养基中,光照培养至种子萌发长出子叶至3-5叶一心。将无菌草莓叶片切去叶尖和基端,切成0.5cm2的小块,将切好的叶片转移至农杆菌侵染液中侵染10min,用无菌滤纸吸干表面菌液,接种于共培养培养基(MS+2.0mg L-1 6BA+0.2mgL-1IBA+AS 200μM),黑暗培养48h。将叶片转移至新的共培养培养基上继续黑暗培养2-4d。推迟筛选后接种于含抗生素的分化培养基(MS+2.0mg L-1 6BA+0.2mg L-1IBA+10g L-1Kan+Carb 400mg·L-1)中,两周后转移至新的分化培养基(20g L-1Kan),每两周转移一次,至长出抗性芽,抗性芽接入生根培养基(MS+IAA 0.2mg·L-1+Carb 200mg·L-1)中,待发育成完整植株后移栽至温室中,获得转化空载体及转VvNAC基因的抗性草莓植株(如图5所示,A为愈伤组织再生抗性芽;B为抗性芽转移至生根培养基;C为转基因植株移栽至营养钵中)。
2、转基因草莓植株的检测
用无液氮DNA快速提取法提取抗性草莓植株叶片DNA,作为模板,设计特异引物两对。
其序列如下所示:
转基因检测-F:5'-CCTAACAGAACTCGCCGTAAAG-3'(如SEQ ID NO.13所示);
转基因检测-R:5'-GCCGGTGGTGCAGATGAAC-3'(如SEQ ID NO.14所示)。该引物为根据pCAMBIA2300载体上报告基因GFP和CaMV 35S启动子的序列来设计的,通过检测选载体和目的基因是否存在来说明转基因是否成功。
检测体系:模板:2μL;正向引物1μL;反向引物1μL;rTaq酶0.25μL;dNTP2μL;Buffer2.5μL;水16.25μL。PCR扩增程序:94℃,3min;94℃,30s;57℃,60s;72℃,2min,29个循环;72℃,5min;4℃保存。PCR产物进行0.8%琼脂糖凝胶电泳,以DNA Mark DL 2000为标样,检测PCR产物。分别以pCAMBIA2300-VvNAC质粒DNA和未转化的植株DNA PCR产物为阳性和阴性对照。检测结果如图6所示,其中M为Maker,N为未转化的植株DNA阴性对照,P为质粒DNA阳性对照,其中泳道4、6为空载体转入到草莓植株中,目的基因未转入草莓植株中,泳道2未检测到任何条带,泳道1、3、5三个株系包含了目的基因条带,为VvNAC转基因阳性植株,分别命名为OE1、OE3、OE5。
3、转VvNAC基因的草莓果实的表型变化
在实验中发现,在开花后28d,转基因植株草莓果实达到了成熟;然而转化空载体的植株以及野生型植株,在开花后28d,草莓果实还没有成熟。结果如图7所示,其中转入空载体的植株草莓果实未完全成熟,而转入VvNAC基因的转基因植株(OE1、OE3、OE5)草莓果实已经成熟。因此,VvNAC基因对于草莓果实成熟具有促进作用。
4、草莓果实中成熟相关基因的表达检测
在开花后28d,采集野生型、转化空载体及转VvNAC基因的草莓果实,采用SDS/酚法提取果实总RNA,按PrimeScriptTM RT-PCR Kit说明进行反转录。Real-time PCR按照TAKARA公司的SYBR Premix Ex TMTaq II试剂盒进行操作。反应体系为:模板1μL,SYBR Mix 12.5μL,正反向引物各1μL,灭菌蒸馏水补齐至25μL。反应程序为:95℃5min;95℃30S,58℃30S,72℃30S,30个循环;72℃5min;4℃10min。PCR反应在Bio-Rad公司的iCycler iQ5 Real-timePCR仪上进行。Thresh值按PCR仪默认为30,分别记录每个反应荧光信号由本底进入指数增长阶段的拐点所对应的循环数(threshold cycle,Ct)。
用2-△△Ct法检测草莓果实中成熟相关基因的表达水平,分别为VvNAC基因、FaCHS基因、FaF3H基因、FaUFGT基因、FaDFR基因,检测时使用FaActin基因作为内参基因。所用引物如下所示:

Qt-FaActin-F:5'-TGGGTTTGCTGGAGATGAT-3'(如SEQ ID NO.25所示);
Qt-FaActin-R:5'-CAGTTAGGAGAACTGGGTGC-3'(如SEQ ID NO.26所示)。
结果如图8所示,从图8中可以看出,与野生型和转空载体植株相比,转VvNAC基因的草莓果实(OE1、OE3、OE5)中VvNAC基因、FaCHS基因、FaF3H基因、FaUFGT基因,FaDFR基因的表达量明显升高。说明VvNAC基因对于FaCHS基因、FaF3H基因、FaUFGT基因,FaDFR基因的表达具有促进作用。
综上,本发明通过植物基因工程技术,从‘京秀’葡萄果实中分离克隆出与果实成熟相关基因VvNAC完整编码区段的DNA片段,并验证了该基因的功能,发现超量表达之后转基因草莓果实成熟期提前6-8d。
