Description
技术领域
本发明涉及生物技术领域,具体地,涉及一种抗草甘膦的植物及其制法。
背景技术
田间杂草生长过盛会影响作物的生长,导致作物减产,因此,除草是保证农作物产量的必要手段,开发抗除草剂作物对规模化集约化种植生产非常重要,已成为遗传育种的一个重要方向。草甘膦是一种低毒、高效、广谱、低残留的除草剂,在除草剂市场占有主导地位。其作用机理主要是竞争性抑制莽草酸途径中5-烯醇丙酮酰莽草酸-3磷酸合成酶(EPSPS)的活性,导致芳香族氨基酸合成受阻,最终造成植物的死亡。
EPSPS酶的基序在所有植物和大多数细菌中的酶都是保守的,这个基序对于结合磷酸烯醇丙酮酸(PEP)或其竞争性抑制剂草甘膦至关重要。
草甘膦已在全球范围内应用了近半个世纪,世界范围内的科学家在近20年对EPSPS蛋白进行了大量、广泛的研究和分子进化,也有一些报道显示EPSPS进化后对草甘膦产生了部分耐受效果,但到目前为止都未有任何商业化,说明这些位点的进化尚不能满足实际生产应用的要求。
有报道指出,目前有部分杂草已有明显的草甘膦抗性,尤其是其中的一个来着鹅草的天然突变,称之为TIPS突变(T102I/P106S),使其对草甘膦产生了显著的抗性。然而在目前为止的报道中,还没有发现栽培作物中有自发诱导的TIPS双突变,这可能是因为自然发生两个核苷酸的概率很低。
目前报道了利用基因编辑对水稻的EPSPS基因进行了精准编辑,获得了含有TIPS突变的水稻,其编辑后的水稻具有显著抗草甘膦抗性,与上述天然突变体一致。但是进一步的研究发现,TIPS是一个致死突变,无法获得能稳定遗传的纯合子。这一致命缺陷使该TIPS位点仍旧无法应用于实际生产。
寻找优良的抗除草剂基因一种是农业育种界的重要目标,但仅靠植物自身的基因突变是及其漫长且随机的。
常规的育种手段几乎无法获得具有特异性突变的突变体,常规转基因技术导入外源基因,产生的生物安全隐患也令人困扰。
并且,目前EPSPS基因的TIPS突变虽然可以使作物获得高抗草甘膦的特性,但也会使植株纯合致死。
因此,本领域迫切需要开发一种可以导入自然界中产生的EPSPS酶TIPS突变,使植物获得抗草甘膦特性的同时,还可以获得稳定遗传的高抗草苷酸特性,并且极大地缩短了新品种的育种年限的方法。

本领域的技术人员熟知的方法能用于构建含突变的酶保守区的编码DNA序列和合适的转录/翻译控制信号的载体。这些方法包括体外重组DNA技术、DNA合成技术、体内重组技术等。所述的DNA序列可有效连接到载体中的适当启动子上,以指导mRNA合成。载体还包括翻译起始用的核糖体结合位点和转录终止子。
此外,载体优选地包含一个或多个选择性标记基因,以提供用于选择转化的宿主细胞的表型性状,如真核细胞培养用的二氢叶酸还原酶、新霉素抗性以及绿色荧光蛋白(GFP),或用于大肠杆菌的四环素或氨苄青霉素抗性。
包含上述的适当DNA序列以及适当启动子或者控制序列的载体,可以用于转化适当的宿主细胞。
宿主细胞可以是原核细胞,如细菌细胞;或是低等真核细胞,如酵母细胞;或是高等真核细胞,如植物细胞(如农作物和林业植物的细胞)。代表性例子有:大肠杆菌,链霉菌属、农杆菌;真菌细胞如酵母;植物细胞、动物细胞等。
本发明的多核苷酸在高等真核细胞中表达时,如果在载体中插入增强子序列时将会使转录得到增强。增强子是DNA的顺式作用因子,通常大约有10到300个碱基对,作用于启动子以增强基因的转录。
本领域一般技术人员都清楚如何选择适当的载体、启动子、增强子和宿主细胞。
用重组DNA转化宿主细胞可用本领域技术人员熟知的常规技术进行。当宿主为原核生物如大肠杆菌时,能吸收DNA的感受态细胞可在指数生长期后收获,用CaCl2法处理,所用的步骤在本领域众所周知。另一种方法是使用MgCl2。如果需要,转化也可用电穿孔的方法进行。当宿主是真核生物,可选用如下的DNA转染方法:磷酸钙共沉淀法,常规机械方法如显微注射、电穿孔、脂质体包装等。
转化植物也可使用农杆菌转化或基因枪转化等方法,例如叶盘法。对于转化的植物细胞、组织或器官可以用常规方法再生成植株,从而获得除草剂耐受性或抗性改变的植物。
也可以利用基因编辑技术直接对含有n个拷贝(n为≥4的偶数)EPSPS基因的目标植物基因组中的EPSPS酶保守区进行编辑,从而使植物细胞中的部分而非全部的EPSPS基因所对应的EPSPS酶保守区(SEQ ID NO.1,L F L G N A G T AM R P L)中的苏氨酸(T)和/或脯氨酸(P)发生突变。代表性的基因编辑技术包括CRISPR基因编辑体系、易错PCR、基因重组、TALEN和ZFN。
CRISPR/Cas(clustered regularly interspaced short palindromic repeats/CRISPR-associated proteins)系统为细菌与古生菌中抵御外源病毒或质粒DNA入侵的获得性免疫系统。该系统的核酸酶在crRNA的指导下识别并降解外源DNA。其中,II型CRISPR/Cas系统组成简单,仅包括一个核酸酶Cas9与tracrRNA:crRNA二聚体便可完成识别和切割功能。CRISPR/Cas9系统以其设计操纵简便、编辑高效与通用性广等优势迅速成为新一代的基因组编辑技术,已被广泛应用于人、小鼠、大鼠、斑马鱼、秀丽隐杆线虫、植物、真菌与细菌等不同物种。
TR-HDR编辑技术是一种常规的基因编辑技术,具体详见文献(Yuming Lu et al.,2020)。
应用
本发明可以用于植物基因工程领域,用于植物研究和育种,尤其是具有经济价值的农作物、林业作物或园艺植物的遗传改良。
本发明的主要优点包括:
(1)本发明首次发现,对多倍体植物(比如2n倍体植物,n为≥2的正整数)进行基因编辑,将EPSPS基因所对应的EPSPS酶保守区(SEQ ID NO.1,L F L G N A G T A M R P L)中的苏氨酸(T)突变为异亮氨酸(I),和/或脯氨酸(P)突变为丝氨酸(S),所获得的植物既具有高抗除草剂(比如草甘膦)的特性,又具有可稳定遗传。
(2)本发明应用基因编辑技术,使用高效的可以实现特异性位点碱基替换的方法,实现植物基因组的碱基定点突变,即EPSPS酶保守基序上的TIPS双突变。该方法可以导入自然界中产生的EPSPS酶TIPS突变,使植物获得抗草甘膦特性的同时,极大地缩短了新品种的育种年限。
(3)本发明将把TIPS突变应用于多倍体中获得纯合植株,来使作物可以获得稳定遗传的高抗草苷酸特性。
(4)本发明的方法可以使植物具有天然的高抗草甘膦特性,并且可以进行稳定的遗传。
(5)本发明提供可以进行精确碱基序列替换的基因编辑方法,对EPSPS基因进行精确定点编辑,使其替换为具有天然突变的高抗甘膦酸特性的EPSPS(TIPS)基因。本发明还提供了一种对植物进行改造的方法:包括利用植物基因遗传转化技术将上述基因编辑系统导入植物细胞,随后经分化筛选培育成相应的基因编辑植株。所获得的植株经基因型检测分析后,我们将得到一些具有高抗草甘膦的能力的植株。
(6)本发明提供了上述高抗草甘膦基因的应用方法:在二倍体植物中,替换后的EPSPS(TIPS)基因具有纯合致死的特性,我们可以对四倍体作物进行基因编辑,从而使作物可以成活同时具有可以稳定遗传的抗草甘膦能力,并且这种能力来自于自然界的天然突变。作物可以是六倍体小麦、四倍体棉花、油菜、水稻、古多倍体的大豆等。
(7)本发明提供的抗草甘膦基因氨基酸序列可以有不同的核苷酸序列变异,包括但不限于用不同密码子编译同一个氨基酸获得的核苷酸序列,这些序列都编码相同活性的蛋白质多态。这种核苷酸序列的变异方法可以用不同的分子生物学及遗传转化技术实现,包括但不限于介绍的基因编辑方法,base editing或prime editing方法,遗传转化方法包括但不限于农杆菌侵染法、基因枪轰击法等。本发明理论上适用于所有植物,包括双子叶植物、单子叶植物。
(8)本发明可以对植物基因组进行精准的定点修饰,获得所需的基因型。同时,国家基因编辑农作物相关政策已于近期出台,明确指出相关基因编辑作物将有别于传统转基因,商业化更加明确和便捷。将基因编辑技术应用与EPSPS基因的精准修饰,有望获得抗草甘膦的植株,具有切实的应用前景。
(9)本发明要解决的问题就是TIPS的纯合致死问题,目标是通过精准编辑获得含有TIPS突变的抗草甘膦植物,使其能够稳定遗传,用于生产实践。本发明通过基因编辑含有多个拷贝的EPSPS基因的植物(例如,多倍体植物),使其中的一个或者多个EPSPS(非全部)产生TIPS修饰,从而实现抗草甘膦的同时,能够稳定遗传。
下面结合具体实施例,进一步阐述本发明。应理解,这些实施例仅用于说明本发明而不用于限制本发明的范围。下列实施例中未注明具体条件的实验方法,通常按照常规条件如Sambrook等人,分子克隆:实验室手册(New York:Cold Spring Harbor LaboratoryPress,1989)中所述的条件,或按照制造厂商所建议的条件。除非另外说明,否则百分比和份数按重量计算。本发明中所涉及的实验材料和试剂如无特殊说明均可从市售渠道获得。
实施例1设计EPSPS酶保守区的氨基酸替换
本发明的EPSPS突变基因EPSPS(TIPS)来自于自然界中的自发突变,它是EPSPS基因在植物EPSPS酶保守区(L F L G N A G T A M R P L(SEQ ID NO.1))发生定向双氨基酸置换后获得的基因。
EPSPS基因在EPSPS酶保守区发生TIPS双氨基酸置换后的EPSPS(TIPS)基因EPSPS酶保守区序列为L F L G N A G I A M R S L(SEQ ID NO.2)。
实施例2EPSPS酶保守区氨基酸替换的实现
蛋白质由DNA转录的RNA翻译而来,三个碱基能决定的那个一个氨基酸而作为一个密码子,密码子具有简并性,同一个氨基酸具有两个或更多的密码子。
为解决上述氨基酸替换的问题,我们需要将上述EPSPS基因的EPSPS酶保守区一个T氨基酸替换为I,一个P氨基酸替换为S。那么,这个苏氨酸的密码子可以替换为异亮氨酸的任一密码子:AUU,AUC,AUA;脯氨酸的密码子可以替换为丝氨酸的任一密码子:UCU,UCC,UCA,UCG,AGU,AGC。在基因组中,上述苏氨酸的位点碱基可以替换为ATT,ATC,ATA,脯氨酸的位点可以替换为TCT,TCC,TCA,TCG,AGT,AGC。
实施例3使用基因编辑方法,实现EPSPS(TIPS)基因在植物中的表达
使用常规的基因编辑方法(比如TR-HDR策略或prime editing),结合常规的遗传转化技术(比如基因枪法或农杆菌侵染法),对植物基因组中EPSPS基因的EPSPS酶保守区进行精确的基因组特异性碱基编辑,使被编辑的T0代植物获得突变后的EPSPS(TIPS)基因。通过常规的遗传转化技术(比如基因枪法或农杆菌侵染法)导入的载体含有筛选标记,我们利用筛选标记可以从分化幼苗中筛选出T0代的转基因幼苗。
T0代植株拥有突变后的EPSPS(TIPS)基因,具有了一定的对草甘膦的抗性,一般通过基因编辑获得的转基因T0代植株通常为嵌合/杂合型。我们需要将T0代转基因幼苗进行繁育,获得的T1代植株,一部分T1代植株会拥有纯合的EPSPS(TIPS)基因,纯合突变体的遗传率为100%,因此,转化后的一部分T1代植株将会具有可以稳定遗传的高抗草甘膦特性。
实施例4应用TR-HDR策略,实现EPSPS基因的TIPS精确序列替换在大豆中的应用
大豆(学名:Glycine max(Linn.)Merr.),虽然是一种二倍体作物,但是是由古四倍体演变而来,有丰富的重复序列。大豆的基因组中,有两个EPSPS基因,分别为GmEPSPS01和GmEPSPS02,这两个EPSPS基因都有EPSPS酶保守区。大豆是我国重要的粮食和油料作物,由于草甘膦除草剂的广泛应用,抗草甘膦大豆在我国粮食产业中占据这非常重要的地位,但是很多转基因作物的专利大多掌握在欧美等发达国家手中,因此,如何在保证我国粮食安全和农业可持续发展的的前提下,找到一条仅靠农作物自身基因突变,获取作物抗除草剂等优良性状基因的路径是目前的焦点。
本发明以大豆基因GmEPSPS02为例,应用TR-HDR策略对其进行精准碱基替换,获得具有可稳定遗传的高抗草甘膦除草剂特性的大豆。具体包括一下步骤:
步骤一、对大豆GmEPSPS02基因进行分析
大豆GmEPSPS02基因序列如SEQ ID NO.3所示,
大豆GmEPSPS02基因在植物EPSPS酶保守区氨基酸序列第177到第189位(L F L GN A G T A M R P L,SEQ ID NO.1)发生定向双氨基酸置换后的基因为mGmEPSPS1(TIPS)基因(第184位氨基酸由T变为I,同时第188位氨基酸由P变为S突变后的编码基因序列,氨基酸序列替换为L F L G N A G I A M R S L(SEQ ID NO.2)。
步骤二、大豆GmEPSPS02基因双氨基酸替换的基因编辑方案设计
为了实现大豆GmEPSPS02基因的碱基替换,我们设计一种串联重复-同源性定向修复方法,TR-HDR策略,如图1所示,设计一个sgRNA靶向切割位点,构建于相应的CRISPR/Cas9载体上;合成一个与目标序列和期望的碱基替代具有同源性5-磷酸化双链寡核苷酸(dsODN)。
在dsODN这个双链DNA的5’端和3’端带有两个硫代磷酸链,使寡核苷酸可以强有力的靶向整合,磷酸化修饰旨在稳定细胞中的寡核苷酸,5’磷酸化可以促进非同源端连接(NHEJ),这是修复双链断裂(DSBs)的主要途径。
在这种策略中,带有sgRNA特异性切割靶点的CRISPR/Cas9载体会在基因组上的EPSPS基因保守区相应位点进行切割,我们设计的供体寡核苷酸dsODN被插入到目标位点,可能会通过NHEJ,于侧翼基因组序列形成串联重复结构。该寡核苷酸还被设计成在插入时为相同的sgRNA形成一个靶位点,在新形成的sgRNA靶位点上的DSB有望触发串联重复序列之间的同源性定向修复HDR,从而使目标序列被插入的同源序列取代。
根据TR-HDR策列及大豆GmEPSPS02基因分析,GmEPSPS02基因待编辑的氨基酸为184Thr、188Pro,我们为此在基因组上设计sgRNA1,序列为TTGCAGTACCAGCATTTCCAAGG。将上述设计的sgRNA1进行合成,两头设计保护碱基及酶切位点,构建至相应的CRISPR/Cas9载体中(CRISPR/Cas9(sgRNA)041,SEQ ID NO.4),导入植物细胞后会在基因组上的特异性靶位点进行切割。该载体上含有basta筛选标记,可用于转化后的筛选。
设计寡核苷酸序列:GAACGCTGGTATTGCAATGCGTAGTTTGACAGCAGCTGTGGTTGCTGCAGGTGGAAATGCAAGGTCTGTTTTTTTTTTTTTTGTTCAGCATAATCTTTGCCTTGG,合成化学修饰双链寡核苷酸的dsODN,如图2。用于插入目标位点进行碱基替换,碱基替换后的GmEPSPS02序列为SEQID NO.5。
步骤三、遗传转化
我们使用常规的基因枪法对大豆进行遗传转化。用粒子轰击将上述dsODN与插入sgRNA的CRISPR/Cas9质粒混合物导入大豆的胚尖细胞中,利用CRISPR上的basta标记对转化后的子叶节进行筛选。经过两轮的basta筛选,获得了上百株大豆转基因幼苗。
步骤四、基因型检测
我们将筛选出来的大豆幼苗提取DNA,用特异性引物扩增鉴定,引物如表1所示。
表1
通过供体特异性扩增引物F1+R2,我们鉴定出了11株含有正向dsDON插入的突变体,通过插入位点两侧引物(F1+R1)目标区域,我们从其中鉴定出11株中有2株含有无缝连接,如图3,a、b。
步骤五、获得具有高抗草甘膦特性并能稳定遗传的大豆
在T0代中,大多数的TR-HDR编辑植株都是嵌合/杂合型,我们将T0代植株自花授粉获得T1代,T1代获得的纯合GmEPSPS02(TIPS)基因遗传率为100%。
我们将筛选出来的大豆幼苗提取DNA进行测序,测序结果显示有一些突变体T1代植株含有所设计的纯合碱基替换,如图3c。
我们用草甘膦喷施T1,如图4,T1代植株相对野生型具有明显的抗草甘膦特性,并且植株通过TR-HDR编辑获得的草甘膦抗性可以稳定的遗传给下一代。
实施例3、实现EPSPS基因的TIPS精确序列替换在水稻中的应用
水稻是世界最主要的粮食作物之一,为全世界一半以上的人口提供主粮。除了二倍体栽培稻,还有多倍体的水稻品种。我们对四倍体水稻的EPSPS基因进行编辑。
步骤一、对水稻OsEPSPS基因进行分析
水稻OsEPSPS基因为SEQ ID NO.6,其保守序列为氨基酸序列第95到第107位(L FL G N A G T A M R P L,SEQ ID NO.1),其中引入两个氨基酸位点的置换:第102号氨基酸从苏氨酸替换为异亮氨酸,第106号氨基酸从脯氨酸替换为丝氨酸。替换后的基因为OsEPSPS(TIPS)基因,其氨基酸序列为L F L G N A G I A M R S L(SEQ ID NO.2)。
步骤二、对水稻OsEPSPS基因双氨基酸替换的基因编辑方案设计
对水稻的OsEPSPS基因的编辑,我们选择了prime editing的方法,该方法不需要供体DNA,就可以对基因组目标位点进行特异性的序列更改。针对水稻OsEPSPS基因,我们设计了一个编辑系统如图5,由三部分组成:nCas9-MMLV融合蛋白、一个prime editingguiding RNA(peg RNA)和一个small guide RNA(sgRNA)。peg RNA含有SG,可以使融合人蛋白靶向目标DNA同时与目标DNA杂交,还包含我们设想的可以取代目标DNA的遗传信息,sgRNA切割未编辑的DNA,有利于DNA的修复。通过编辑器的切割和修复功能,目标DNA序列将会被替换为我们所设想的序列。我们将这个编辑系统整合为植物二元载体pCXPE01-OsEPSPS(pCXPE01二元载体获自百格基因科技(江苏)有限公司,使用常规分子构建方法将靶点克隆到pCXPE01上,获得了pCXPE01-OsEPSPS质粒载体),该载体含有潮霉素抗性基因,载体pCXPE01-OsEPSPS的序列为SEQ ID NO.7。编辑后的水稻OsEPSPS(TIPS)序列为SEQ IDNO.8。
步骤三、遗传转化
我们用常规的农杆菌侵染法对水稻愈伤组织进行遗传转化。将设计好的上述质粒(pCXPE01-OsEPSPS,SEQ ID NO.7)转化进入农杆菌,经培养后的农杆菌对水稻愈伤细胞进行侵染,愈伤组织共培养后筛选分化成幼苗,经过两轮的潮霉素筛选,获得了上百株水稻转基因幼苗。
步骤四、基因型检测
我们将筛选出来的水稻转基因幼苗取样提取DNA,用特异性引物进行扩增,引物如表2所示。
表2
通过表2中的供体特异性扩增引物OsEPSPS-F+OsEPSPS-R,我们鉴定出了3株被编辑的突变体,如图6a所示。
步骤五、获得具有高抗草甘膦特性并能稳定遗传的水稻
在T0代中,大多数的基因编辑植株都是嵌合/杂合型,我们将T0代植株自花授粉获得T1代,T1代获得的纯合OsEPSPS(TIPS)基因遗传率为100%。
我们将筛选出来的水稻幼苗提取DNA进行测序,测序结果显示有一些突变体T1代植株含有所设计的纯合碱基替换,如图6b。
我们用草甘膦喷施T1代水稻TIPS突变体植株,如图7,T1代植株相对野生型具有明显的抗草甘膦特性,并且植株通过基因编辑获得的草甘膦抗性可以稳定的遗传给下一代。
并且对大豆的GmEPSPS01和GmEPSPS02均进行上述突变,大豆会纯合致死。
