Abstract
本发明公开了一种基于基因编辑技术快速培育玉米单倍体诱导系的方法。该方法包括如下步骤:(1)用基因编辑系统编辑目的玉米,获得T0代转基因玉米;基因编辑系统中含有sgRNA编码基因;sgRNA在目的玉米中识别的靶标DNA为编码ZmDMP蛋白的DNA片段和编码ZmPLA1蛋白的DNA片段;(2)将T0代转基因玉米自交N代,得到TN代转基因玉米;N为1以上的自然数;ZmPLA1基因和ZmDMP基因发生突变的TN代转基因玉米即为玉米单倍体诱导系。获得的玉米单倍体诱导系,不仅培育的时间大大缩短,而且单倍体诱导率也较高。本发明具有重要的应用价值。
Description
技术领域
本发明属于生物技术领域,具体涉及一种基于基因编辑技术快速培育玉米单倍体诱导系的方法。
背景技术
玉米是世界三大粮食作物之一,也是我国种植面积第一大的作物,并且我国玉米杂交种的种植面积占全部的97%(Li,2009)。优良玉米自交系的选育是玉米利用杂种优势、选育优良杂交种的基础和关键。传统的选育方法需要7-8个世代连续自交才能够获得较为稳定的自交系,而利用单倍体育种技术只需2个世代(Weber,2014),大大的缩短了育种年限。单倍体育种技术因此被国内外种业公司规模化应用,成为现代化玉米育种三大核心技术之一(Geiger&Gordillo,2009;陈绍江等,2012)。
单倍体的产生是单倍体技术应用的前提。据现有文献报道,玉米单倍体可自然产生,也可通过体外花粉离体培养、子房离体培养或“用各种化学的、生物的刺激物诱导”产生。目前,基于孤雌生殖诱导系诱导产生单倍体的方法以其低廉的成本和快速获得大量单倍体等优点,逐渐成为玉米单倍体生产的主要途径。
诱导系是单倍体育种技术的基础和起点,但是诱导系的选育过程极其耗费时力,特别是对于诱导率的选择。因此,全球多家科研单位对于Stock6及其衍生系诱导产生孤雌生殖单倍体的遗传基础和生物学基础进行了大量的研究。结果表明,玉米孤雌生殖诱导能够产生玉米单倍体这一性状是可遗传的,并受到多个遗传位点的控制:等(1999)首次检测到2个控制诱导率性状的遗传位点,分别位于1号染色体和2号染色体,共能解释约17.9%的表型变异;Barrant等(2008)同样在1号染色体相同区域检测到了一个既影响单倍体诱导率又引起群体偏分离的主效QTL;Prigge等(2012)利用多个群体进行全基因组扫描,共发现8个控制诱导率的遗传位点,其中有2个为主效QTL,位于1号染色体上的1.04bin区域的主效QTL位点qhir1能够解释66%的遗传变异,位于9号染色上的9.01bin区域的主效QTL位点qhir8能够解释20%的遗传变异。其中qhir1已被定位到了243kb的物理区间(Dong Xet al.,2013),并成功在该区间克隆到一个磷脂酶基因ZmPLA1,该基因功能丧失能够诱导单倍体的产生(Kelliher T et al.,2017;Liu C et al,2017;Gilles L M,et al,2017)。qhir8作为另一个主效QTL,能够显著提高单倍体诱导率。Liu等(2015)对qhir8进行了精细定位,以诱导能力低的诱导系CAUHOI(2%)和诱导率高的诱导系UH400(8%)杂交后代为定位群体,最终将qhir8定位到了标记4292232和umc1867之间,其物理距离约789kb。后来研究有进一步将在qhir8定位于318bp区间,并在该区间克隆到一个编码DUF679结构域膜蛋白(DUF679 domain membrane protein)的基因ZmDMP,该基因突变后能在ZmPLA1基因的基础上极大提高单倍体诱导能力。
虽然以上的结果为诱导系的选育提供了有效的分子辅助选择标记,提高了诱导系的选育效率,但是该选育过程所需的时间还未能得到有效缩短。

二、转基因玉米的获得及其验证
1、EHA105/pBUE411-sgRNA的获得
将重组质粒pBUE411-sgRNA通过热激转化至农杆菌EHA105感受态细胞,得到重组农杆菌,命名为EHA105/pBUE411-sgRNA。
2、T0代转基因玉米的获得
采用农杆菌侵染法,将EHA105/pBUE411-sgRNA转化至玉米B104幼胚,经过筛选、分化和生根,获得26株T0代转基因玉米。
3、T0代转基因玉米突变类型的分子检测
(1)检测26株T0代转基因玉米中ZmDMP基因的突变类型
(1-1)分别提取26株T0代转基因玉米叶片的基因组DNA并以其作为模板,采用ZmDMP_F:5’-TGAACTCAAGCACTGCCTAACG-3’和ZmDMP_R:5’-CCGGTCCTGAACAGCGACA-3’组成的引物对甲进行PCR扩增,得到相应的PCR扩增产物。
(1-2)将各个PCR扩增产物进行Sanger测序。
(1-3)将步骤(1-2)得到的测序结果分别与序列表中序列1自5’末端起第78-438位所示的DNA片段(简称目标DNA片段甲)进行比对,然后进行如下判断:如果测序结果与目标DNA片段甲比对有碱基插入、缺少或替换时,则相应的T0代转基因玉米的ZmDMP基因发生突变;如果测序结果与目标DNA片段甲比对无差异,则相应的T0代转基因玉米的ZmDMP基因未发生突变。
(2)检测26株T0代转基因玉米中ZmPLA1基因的突变类型
(2-1)分别提取26株T0代转基因玉米叶片的基因组DNA并以其作为模板,采用ZmPLA1_F:5’-CCCTCGACGAGTATCTATAGC-3’和ZmPLA1_R:5’-CACTTGCCGTTGTACTTTGG-3’组成的引物对乙进行PCR扩增,得到相应的PCR扩增产物。
(2-2)将各个PCR扩增产物进行Sanger测序。
(2-3)将步骤(2-2)得到的测序结果分别与序列表中序列3自5’末端起第28-625位所示的DNA片段(简称目标DNA片段乙)进行比对,然后进行如下判断:如果测序结果与目标DNA片段乙比对有碱基插入、缺少或替换时,则相应的T0代转基因玉米的ZmPLA1基因发生突变;如果测序结果与目标DNA片段乙比对无差异,则相应的T0代转基因玉米的ZmPLA1基因未发生突变。
实验结果如下:26株T0代转基因玉米中,18株T0代转基因玉米的ZmPLA1基因和ZmDMP基因均发生突变,5株T0代转基因玉米的ZmPLA1基因发生突变且ZmDMP基因未发生突变,2株T0代转基因玉米的ZmDMP基因发生突变且ZmPLA1基因未发生突变,1株T0代转基因玉米的ZmPLA1基因和ZmDMP基因均未发生突变。ZmPLA1基因和/或ZmDMP基因发生突变的T0代转基因玉米即为阳性T0代转基因玉米(即共获得25株阳性T0代转基因玉米)。
4、T1代转基因玉米的获得和基因型鉴定
(1)将步骤3得到的阳性T0代转基因玉米进行自交,收获种子后再播种,得到T1代转基因玉米。
(2)分别提取T1代转基因玉米叶片的基因组DNA并以其作为模板,采用引物对甲或引物对乙进行PCR扩增,得到PCR扩增产物。
(3)将步骤(2)得到的PCR扩增产物进行Sanger测序。
(4)将步骤(3)中采用引物对甲进行PCR扩增得到的PCR扩增产物的测序结果分别与目标DNA片段甲进行比对,然后进行如下判断:如果测序结果与目标DNA片段甲比对有碱基插入、缺少或替换时,则相应的T1代转基因玉米的ZmDMP基因发生突变;如果测序结果与目标DNA片段甲比对无差异,则相应的T1代转基因玉米的ZmDMP基因未发生突变。将步骤(3)中采用引物对乙进行PCR扩增得到的PCR扩增产物的测序结果分别与目标DNA片段乙进行比对,然后进行如下判断:如果测序结果与目标DNA片段乙比对有碱基插入、缺少或替换时,则相应的T1代转基因玉米的ZmPLA1基因发生突变;如果测序结果与目标DNA片段乙比对无差异,则相应的T1代转基因玉米的ZmPLA1基因未发生突变。
根据测序结果,将T1代转基因玉米的基因型分为如下四种:一是T1代转基因玉米的ZmPLA1基因和ZmDMP基因均未发生突变,基因型记为ZmPLA1-ZmDMP;二是T1代转基因玉米的ZmDMP基因发生突变且ZmPLA1基因未发生突变(即ZmDMP基因单独纯合突变),基因型记为ZmPLA1-zmdmp;三是T1代转基因玉米的ZmPLA1基因发生突变且ZmDMP基因未发生突变(即ZmPLA1基因单独纯合突变),基因型记为zmpla1-ZmDMP;四是T1代转基因玉米的ZmPLA1基因和ZmDMP基因均发生突变,基因型记为zmpla1-zmdmp。
ZmPLA1基因和ZmDMP基因发生突变的T1代转基因玉米(即基因型为zmpla1-zmdmp的T1代转基因玉米)即本发明获得的玉米单倍体诱导系。
实施例2、玉米单倍体诱导系的诱导率评价
一、单倍体的产生
分别以实施例1中获得的T1代转基因玉米(ZmPLA1-ZmDMP、ZmPLA1-zmdmp、zmpla1-ZmDMP和zmpla1-zmdmp均有)为父本,以郑单958或京科968为母本,杂交(进行杂交的穗数见表2中第3列),得到玉米籽粒。
统计正常籽粒数。统计结果见表2中第5列。
表2
二、单倍体的鉴定
A、田间表型鉴定
将步骤一得到的玉米籽粒播种于田间,正常田间管理,观察玉米植株的单株表型,然后进行如下判断:如果植株矮小、叶片较窄且上冲、株型紧凑、雄性不育,则该玉米植株为单倍体植株;如果植株高大、叶片宽大、披散、育性正常,则该玉米植株为二倍体植株。
B、流式细胞鉴定
(a)分别提取玉米B104幼嫩叶片的细胞核(以下简称104细胞核)和步骤A获得的玉米植株幼嫩叶片的细胞核(以下简称杂交细胞核)。
(b)完成步骤(a)后,采用流式细胞仪检测104细胞核的信号。
(c)完成步骤(b)后,采用流式细胞仪检测杂交细胞核的信号,并进行如下判断:如果杂交细胞核的信号峰与104细胞核信号峰位置相同,该玉米植株被鉴定为二倍体植株(见图1);如果杂交细胞核的信号峰在104细胞核信号峰的一半左右,则该玉米植株被鉴定为单倍体植株(见图2)。
如果玉米植株采用田间表型鉴定和流式细胞鉴定的任一种方法鉴定为单倍体植株,则该玉米植株即为单倍体植株。
统计单倍体株数。统计结果见表2中第4列。
三、计算单倍体诱导率
按照如下公式计算单倍体诱导率。单倍体诱导率=(单倍体株数/正常籽粒数)×100%。
结果见表2中第6列。结果表明,基因型为ZmPLA1-ZmDMP的T1代转基因玉米与母本(郑单958或京科968)杂交后,杂交后代中均不可获得单倍体。基因型为ZmPLA1-zmdmp、zmpla1-ZmDMP或zmpla1-zmdmp的T1代转基因玉米与母本(郑单958或京科968)杂交后,杂交后代中均可获得单倍体;且基因型为zmpla1-zmdmp的单倍体诱导率明显高于ZmPLA1-zmdmp或zmpla1-ZmDMP。由此可见,通过对单倍体诱导基因ZmPLA1和ZmDMP的编辑能快速获得高频的单倍体诱导系。
