技术领域
本发明属于生物高技术领域，公开了用于提高枯草芽孢杆菌自发突变率的质粒。
背景技术
枯草芽孢杆菌(Bacillus subtilis)在发酵工业、农业和环境保护等领域都发挥重要作用。比如枯草芽孢杆菌被用于重组蛋白表达、化合物生产、植物促生、生物防治和污染物降解等。在实际应用之前，通常要对菌株进行驯化和改造，即育种。物理或化学诱变是常用的育种方法，即通过物理或化学手段提高菌株的基因突变频率，然后筛选目标突变株。该方法的缺点是突变效率低和突变谱窄，且存在危险和污染问题。因此，科研人员尝试提高菌株的自发突变频率。具体策略包括敲除菌株的错配修复系统和表达易错型DNA聚合酶等等。然而，理想的方法应该是不改变宿主的基因型，实现可拔插式操作。迄今，枯草芽孢杆菌中尚无这种理想型的突变方法。鉴于此，本发明提供可以提高枯草芽孢杆菌自发突变频率的质粒，导入质粒即可提高宿主的基因突变频率，丢失质粒后宿主的基因突变频率则恢复正常。该质粒可以应用于枯草芽孢杆菌的育种。
发明内容
技术问题：枯草芽孢杆菌是一种重要的微生物，突变育种在该菌的应用中发挥重要作用。然而，物理和化学诱变育种存在突变效率低、突变谱窄以及危险性高等问题。虽然体内自发突变比体外诱变安全，但目前枯草芽孢杆菌中尚无提高自发突变频率的理想方法。本发明借助 CRISPRi(CRISPR interference)技术和过表达易错型DNA聚合酶的方法，提高宿主的自发突变频率。整个操作可通过质粒的转化和消除实现，无需对宿主进行基因敲除。
本发明的目的可通过以下技术方案实现：
本发明所述的质粒可用于提高枯草芽孢杆菌的自发突变频率，进而对枯草芽孢杆菌进行育种。
用于提高枯草芽孢杆菌自发突变频率的质粒，其特征在于，选自pUS20D9M,pUS20XP1以及pUS20XP2中的任意一个；其中，质粒pUS20D9M序列如SEQ ID NO.1所示，质粒pUS20XP1 序列如SEQ ID NO.2所示，质粒pUS20XP2序列如SEQ ID NO.3所示。
上述质粒均用于提高枯草芽孢杆菌自发突变率。该系列质粒主要功能元件是木糖诱导的 dCas9表达盒，木糖诱导的失去校对功能的polC
本发明的原理是抑制错配系统和正常的DNA聚合酶，并表达易错型DNA聚合酶，提高宿主的自发突变频率。根据对突变频率高低的需求，可以通过三种方式实现。第一，将质粒 pUS20D9M转化到枯草芽孢杆菌宿主中，该质粒携带受木糖诱导的dCas9表达盒，可以抑制错配修复基因mutSL(Ginetti et al..1996.Microbiology.226:467-472.doi:10.1099/13500872-142-8-2021)的表达。在添加木糖后，枯草芽孢杆菌中基因mutSL的转录被抑制，导致菌株错配修复系统被干扰，最终菌株的自发突变率增高。第二，将质粒pUS20XP1 转化到染色体整合了木糖诱导的dCas9表达盒的枯草芽孢杆菌宿主中，质粒pUS20XP1包括两个元件，一是抑制正常DNA聚合酶基因polC表达的sgRNA表达盒，另一个是受木糖诱导表达易错型DNA聚合酶PolC
一种提高枯草芽孢杆菌自发突变频率的方法，将本发明所述的任意一种质粒转染枯草芽孢杆菌在含有1％木糖的LB培养基中36℃-38℃培养12h。
质粒pUS20D9M的构建方法，通过同源重组的方式将含有木糖诱导的dCas9表达盒以及干扰mutSL的sgRNA表达盒构建在质粒pUS20上；其中，所述的含有木糖诱导的dCas9表达盒序列如SEQ ID NO.1中第4175bp-8281bp所示；所述的干扰mutSL的sgRNA表达盒序列如SEQ ID NO.1中第第8310bp-8480bp所示。
作为本发明的一种优选，所述的构建方法包括：以质粒pJMP1为模板，用引物P1/P2扩增含有木糖诱导的dCas9表达盒xylR-P
质粒pUS20XP1的构建方法，通过同源重组的方式将木糖诱导失去校对功能的DNA聚合酶 PolC
作为本发明的一种优选，所述的构建方法包括：首先，以枯草芽孢杆菌168基因组为模板，分别用引物P7/P8,P9/P10和P11/P12扩增DNA聚合酶polC
质粒pUS20XP2的构建方法，其特征在于，通过同源重组将片段P
作为本发明的一种优选，所述的构建方法包括：以质粒pUS20XP1为模板，用引物P17/P18 扩增质粒pUS20XP1全部序列；以质粒pUS20D9M为模板，用引物P19/P20扩增后得到片段 P
有益效果：
自发突变是生物体遗传变异和进化的最终来源，提高宿主的自发突变率可以更加有效的增加遗传学上的多样性。通过使用CRISPRi技术干扰与DNA错配修复的相关的基因mutSL和 polC的转录，并诱导表达点突变的polC*提高了枯草芽孢杆菌的自发突变率。在枯草芽孢杆菌中开发了一套有效的，可诱导的，广谱的和基于载体的自发诱变系统，该系统在建库后会随着质粒丢失而消失，有利于菌株性状稳定性的提高。

具体实施方式
实施例1质粒pUS20D9M用于提高枯草芽孢杆菌的自发突变率
大肠杆菌和枯草芽孢杆菌用LB培养基(蛋白胨1％，酵母粉0.5％，氯化钠1％，pH7.0) 在37℃培养。如图1a所示，通过同源重组的方式将含有木糖诱导的dCas9表达盒以及干扰 mutSL的sgRNA表达盒构建在质粒pUS20(Ye et al..2018.J Biotechnol.284:57-62.doi: 10.1016/j.jbiotec.2018.08.001)上。构建流程如下：首先，以质粒pJMP1(Peterset al..2016.Cell. 165:1493-506.doi:10.1016/j.cell.2016.05.003)为模板，用引物P1/P2扩增含有木糖诱导的 dCas9表达盒xylR-P
工作原理如图1b所示，添加木糖后会诱使用CRISPRi技术干扰与DNA错配修复的相关的基因mutSL的转录，由于抑制了mutSL的转录，从而提高了自发突变率。将该质粒转化菌株168中枯草芽孢杆菌168(pUS20D9M)，当在含有1％木糖的LB培养基(蛋白胨1％，酵母粉0.5％，氯化钠1％，pH 7.0)37℃培养12h，枯草芽孢杆菌168(pUS20D9M)比原始枯草芽孢杆菌168提高约428.4倍(使用利福平的突变情况来评估菌体的自发突变率)。在没有木糖诱导的情况下，自发突变率仍比原始菌株168高了约78.5倍(图2)。但质粒pUS20D9M 在建库后可丢失(含有质粒pUS20D9M的菌株在没有抗生素的LB培养基中37℃培养12h后，质粒丢失率为80％)，从而使菌体恢复正常状态。
实施例2质粒pUS20XP1用于提高枯草芽孢杆菌的自发突变率
将含有木糖诱导的dCas9表达盒的染色体整合质粒pJMP1(Peters etal..2016.Cell. 165:1493-506.doi:10.1016/j.cell.2016.05.003)转化到枯草芽孢杆菌168中，在基因lacA处通过双交换后将含有木糖诱导的dCas9表达盒的染色体上，由红霉素抗性筛选得到菌株168D。
如图3所示，通过同源重组的方式将木糖诱导失去校对功能的DNA聚合酶PolC
将质粒pUS20XP1转化菌株168D中得到菌株168D(pUS20XP1)，当在LB培养基中添加木糖后，polC基因的转录被抑制并诱导表达失去校对功能的DNA聚合酶polC*后，菌株的自发突变率明显提高。在含有1％木糖培养12h后，菌株168D(pUS20XP1)比原始菌株168 提高约629.5倍(使用利福平的突变情况来评估菌体的自发突变率)。在没有木糖诱导的情况下，自发突变率仍比原始菌株168高了约52.8倍(图4)。但质粒pUS20XP1在建库后可丢失 (丢失方法同质粒pUS20D9M一致)，从而使菌体恢复正常状态。
实施例3质粒pUS20XP2用于提高枯草芽孢杆菌的自发突变率
为了进一步提高质粒型枯草芽孢杆菌自发突变系统中的自发突变率，尝试将干扰mutSL 系统和表达polC*系统结合在一起，以此构建质粒pUS20XP2(图5)。构建流程如下：首先，以质粒pUS20XP1为模板，用引物P17/P18扩增质粒pUS20XP1全部序列；以质粒pUS20D9M为模板，用引物P19/P20扩增后得到片段P
如图5所示，该质粒含有木糖诱导表达的polC*和两条分别干扰mutSL和polC的sgRNA 表达盒，并将该质粒转化菌株168D中，得到可以通过木糖控制的一株自发突变率更高的菌株。如图6所示，在含有1％木糖培养12h后，菌株168D(pUS20XP2)比WT提高约5128.3倍。在没有木糖诱导的情况下，自发突变率仍比WT高了约437.5倍。综上，该系统有效提高了自发突变率，虽然在不添加诱导剂的情况下也有较高的突变率，但质粒pUS20XP在建库后可丢失(丢失方法同质粒pUS20D9M一致)，从而使菌体恢复正常状态。
