1苏云金芽胞杆菌LM1212质粒缺失对细胞分化的影响显示文摘【目的】苏云金芽胞杆菌LM1212与传统Bt相比,芽胞和晶体形成产生了分化,研究目的是明确质粒缺失对LM1212菌株细胞分化的影响。【方法】采用高温法对含有cry35-like基因启动子与lac Z基因融合质粒的LM(p35'Z)菌株进行内源大质粒缺失。在含X-gal的HCO平板培养初步筛选缺失突变株,进一步提取野生型及突变株的质粒进行脉冲场凝胶电泳分析,并用cry基因引物进行鉴定、激光共聚焦扫描显微镜和光学显微镜观察、芽胞形成率分析及利用SDS-PAGE和LC-MS/MS(Q-TOF)质谱分析质粒缺失对LM1212细胞分化和Cry蛋白表达的影响。【结果】筛选得到两株质粒缺失突变株LM(p35'Z)-W菌株和LM(p35'Z)-DB菌株,在含X-gal的HCO平板上,LM(p35'Z)-W菌株菌落颜色为白色,LM(p35'Z)-DB菌株菌落颜色为深蓝色,说明cry35-like基因启动子活性在这两株菌中受到影响;细胞形态观察发现LM(p35'Z)-DB菌株形成更多晶体产生细胞,LM(p35'Z)-W菌株形成更少晶体产生细胞。SDS-PAGE结果表明LM(p35'Z)-DB菌株Cry蛋白表达量提高,LM(p35'Z)-W菌株Cry蛋白表达量减少。【结论】LM1212质粒缺失可以影响细胞分化和晶体蛋白产量,此发现为深入解析LM1212细胞分化的调控机制和Bt菌株的遗传改良奠定了基础。马丽霞 彭琦 Lereclus Didier 张杰 郭淑元 宋福平 2017微生物学通报2017,44,3:2
