Description

OsKTN80b基因在降低水稻株高方面的应用
技术领域
本发明涉及水稻基因工程领域,具体涉及OsKTN80b基因在降低水稻株高方面的用途。
背景技术
20世纪60年代,矮秆水稻育种的成功,使水稻产量提高了20%-30%,被称为水稻育种的“绿色革命”。矮化育种不仅提高了水稻的抗倒伏能力,而且对于增加种植密度、改善水稻的综合性状都有重要的作用。目前,生产上应用的水稻矮杆基因主要是sd1,存在矮秆基因单一和遗传背景狭窄等缺点,很容易造成遗传上的脆弱性和局限性。此外,其他已知的矮杆和半矮杆基因大多对水稻农艺性状有负面影响,即含有这些矮秆基因的水稻品种农艺性状较差,在实际生产中很难应用,因而限制了水稻矮化育种的发展。
随着生物技术的发展,转基因技术为水稻的矮化育种提供了一种新的途径。目前,已克隆了20多个矮杆及相关基因,其中大部分矮杆基因参与赤霉素(GA)的合成、运输及信号转导途径,如sd1(Sasaki A等,Nature,2002,416(416):701-702;Monna L等,DNAResearch,2002,9(1):11;Wolfgang Spielmeyer等,Proceedings of the NationalAcademy of Science,2002,99(13):9043-9048)、D1(Fujisawa Y等,Proceedings of theNational Academy of Sciences of the United States of America,1999,96(13):7575-7580)、BC12/GDD1(Li J等,Plant Cell,2011,23(2):628-640)、OsSPY(Shimada A等,Plant Journal,2006,48(3):390-402)、D35(Itoh H等,Plant Molecular Biology,2004,54(4):533)、D18(Tong H等,Plant Cell,2014,26(11):4376)、EUI1(Zhu Y等,Plant Cell,2006,18(2):442-456)、GID1(Tanaka N等,Plant Cell&Environment,2006,29(4):619-631)和GID2(Sasaki A等,Science,2003,299(5614):1896-1898)等。这些矮杆基因中,除sd1以外,大多具有“一因多效”的遗传表型,矮化的同时伴随着不利的农艺性状,难以在实际生产中应用。
OsKTN80b是编码微管剪切酶蛋白的基因(Wan L等.Journal of IntegrativePlant Biology,2014,56(7):622-634)。
CRISPR/Cas9系统是一种准确、便捷、高效率的生物基因组编辑工具。该系统仅需要短的gRNA和核酸酶(Cas9)就可以进行特定的生物靶基因的编辑。目前,CRISPR/Cas9系统已在拟南芥、烟草、水稻、小麦、高粱、玉米等植物中实现了定点基因组编辑。

实施例2:OsKTN80b cas9转化水稻
(1)将实施例1所得的两个重组质粒C1和C2,分别通过冻融法导入农杆菌菌株EHA105。每100μl EHA105感受态细胞与0.5-1μg(约2μl)质粒DNA混匀,依次在冰上、液氮和37℃水浴中各放置5min;用新鲜的LB液体培养基稀释至1ml,于28℃摇床培养2-4小时;取出200μl涂布于含抗生素Kan(50μg/ml)和Rif(50μg/ml)的LB平板上,在28℃培养2-3天。从LB平板上挑取农杆菌单菌落接种到3ml含抗生素的LB液体培养基中于28℃摇床培养过夜,第二天按1%接种量转接入50ml含抗生素的LB液体培养基中,在200rpm继续振摇培养至OD600为0.6至0.8左右时,将新鲜的农杆菌菌液在4℃、5000rpm下离心5分钟,收集并重悬于1/3体积的TY液体培养基中,获得含有OsKTN80b敲除载体的农杆菌菌液,分别命名为D1和D2,此时D1或D2即可用于转化水稻各种受体材料。
采用常规的农杆菌转化方法转化水稻日本晴的成熟胚愈伤组织。
(2)将日本晴水稻成熟种子去壳,于75%的酒精浸泡1min,然后用无菌水冲洗3次;加入浓度为50%的次氯酸钠(NaClO)溶液浸泡30min,无菌水洗8-10次,吸去多余水分;接种到诱导培养基上,于光照培养箱中在30℃、光照条件下培养7天左右,至愈伤组织长出;将愈伤组织从种子上分离后转移到继代培养基上,于相同条件下培养1周左右,即可用于农杆菌浸染。
(3)取步骤(1)中保存于-80℃冰箱的农杆菌菌液10μl于5ml YEP培养基(Kan50mg/L;Rif 50mg/L)中,在28℃、200rpm条件下培养24-32h,取1ml菌液于50mL TY+AS培养基中,在28℃培养2-4h,至OD600约0.1-0.2。
(4)将步骤(2)中所得的水稻愈伤组织转入步骤(3)所获得的D1和D2农杆菌悬浮液中,并共孵育30min,用灭菌的滤纸吸除过多的菌液。将浸染后的愈伤组织转移到共培养基MSD+S+AS中,在22℃、黑暗条件下培养2-3天。筛选培养,用液体的MSD培养基清洗从共培养基上转移的愈伤组织,清洗3次,每次10min:用灭菌滤纸吸除多余的培养基,将愈伤组织接入筛选培养基(MSD+CH)中,在30℃、光照条件下培养2-3周;将愈伤组织转入新的筛选培养基中培养4-5周,开始出现新的抗性小愈伤组织,将这些新的愈伤组织分离出来并转接入分化培养基中,在30℃、光照条件下培养2-3周。将繁殖变大的愈伤组织转入新的分化培养基中,在30℃、光照条件下培养3周,新的抗性愈伤组织在分化培养基中培养约30天就开始变绿。将再生的转基因幼苗(大概2-5cm高)转入生根培养基中,于光照培养箱中在25-30℃,16h光照/8小时黑暗条件下培养,获得再生植株。靶位点SG1敲除(农杆菌D1浸染愈伤组织)获得转基因植株,命名为OsKTN80b-1;靶位点SG2敲除(农杆菌D2浸染愈伤组织)获得转基因植株,命名为OsKTN80b-2。将获得的OsKTN80b-1和OsKTN80b-2再生植株移栽到大田种植,提取植株叶片总DNA,经PCR检测(PCR反应体系和程序与实施例1相同),OskTN80b-1和OskTN80b-2的两个敲除靶位点分别获得了17株独立的T0代阳性转基因株系(见图2)。
实施例3:转基因水稻基因组DNA提取、突变体的PCR检测及测序
按照如下方法进行:
采用CTAB法提取实施例2获得的T0代转基因水稻叶片基因组DNA;对T0代的转基因植株的敲除位点进行PCR测序分析。其中PCR扩增体系为:10×buffer for KOD-Plus 2.5μl、KOD plus聚合酶(5U/μl)0.25μL、25mmol/L MgSO4 1μl、dNTPs(2mmol/L)2.5μl、各引物(10μmol/L,Cas9-p80-1F与Cas9-p80-1R)0.5μl、和(10μmol/L,Cas9-p80-2F与Cas9-p80-2R)模板DNA 0.5μl,以超纯水补至25μl。反应条件为94℃2min;94℃20s、58℃30s,68℃60s,30个循环;68℃5min。扩增产物经1%琼脂糖凝胶电泳(电泳缓冲液0.5×TBE),BIORAD凝胶成像系统观察、照相(见图3和图5),并送成都擎科梓熙生物科技有限公司测序。
OsKTN80b敲除位点的测序引物为Cas9-OsKTN80b-1F和Cas9-OsKTN80b-1R:
Cas9-OsKTN80b-1F:5’-GCGGTAGATTCTGCTAGCGT-3’(SEQ ID NO.12),
Cas9-OsKTN80b-1R:5’-TGTTTGGCATTGTTGGACAG-3’(SEQ ID NO.13);
或为Cas9-OsKTN80b-2F和Cas9-OsKTN80b-2R:
Cas9-OsKTN80b-2F:5’-TTGGGCTTCCTTCGTTTAGTGA-3’(SEQ ID NO.14),
Cas9-OsKTN80b-2R:5’-AGTCGAACAGCAACCAATGA-3’(SEQ ID NO.15);
结果在OsKTN80b-1和OsKTN80b-2的两个敲除靶位点共获得了17株独立的阳性转基因株系,测序结果显示17株转基因苗都被敲除,OsKTN80b-1分别获得了缺失CC以及其他突变类型的突变体,OsKTN80b-2获得了A/T碱基的插入以及不同碱基长度缺失的突变体,T0代没有获得纯合的敲除突变体;选择T0代株系中,OsKTN80b-1具有CC碱基缺失的水稻植株(见图4)以及OskTN80b-2含有T碱基插入突变水稻植株(见图6),这两种突变方式导致编码的蛋白分别移码突变后提前终止。种植T1代(T0代自交产生),至成熟期,测定T1代纯合的敲除突变体植株和非转基因野生型植株的株高、拍照,并利用TTEST进行统计学分析野生型和T1代纯合的敲除突变体植株株高差异的显著性。结果(见图7和图8)以非转基因野生型植株株高作为100%,Cas9敲除OsKTN80b基因水稻植株的株高降低了约13-15%。
同时测定了成熟期水稻植株不同节间长度。结果(见表1)显示OsKTN80b基因被敲除水稻植株的第一节间(P1)、第二节间(P2)、第三节间(P3)、第四节间(P4)和第五节间(P5)均小于非转基因水稻。这些结果表明,OsKTN80b基因的功能缺失能够抑制每一节间的延伸。

注:其中Nip为野生型日本晴;Osktn80b为OsKTN80b基因敲除突变体水稻植株。
综上所述,本发明利用CRISPR/Cas9基因编辑技术对OskTN80b基因进行敲除,获得了多个不同突变方式的突变体,其T1代纯合突变的植株都表现为株高降低。说明本发明方法可用于降低水稻株高,提高水稻的抗倒伏能力,最终提高水稻产量。
