近日,中国农业科学院生物技术研究所的科研人员成功培育出高抗低残留抗草甘膦除草剂棉花新品系。该所科研人员将从草甘膦严重污染土壤微生物中克隆到的两个关键的抗草甘膦基因GR79EPSPS和GAT进行植物偏爱性密码子改造,构建仅含GR79EPSPS或GAT单基因和同时含有双基因的植物表达载体,而
Recently, researchers from the Institute of Biotechnology, Chinese Academy of Agricultural Sciences successfully cultivated new cotton lines with high resistance to low residual glyphosate herbicide. The researchers reconstituted the plant-preferred codons for two key glyphosate resistant genes, GR79EPSPS and GAT, which were cloned from glyphosate-contaminated soil microbes to construct a plant-specific codon that contains only the GR79EPSPS or GAT single genes and contains both genes The plant expression vector, however
