defective mutant

基本解释

A white colony mutant, 1-40-271, was normal in sporulation and spore germination, but defective in appressorium development and totally lost in pathogenicity.
突变体1-40-271菌落呈白色，产孢与萌发均正常，但萌发后即便在人工疏水表面上也不能形成附着胞，且丧失了致病性；
The repressor gene and its allele-a temperature sensitive mutant have been cloned from the defective prophage PBSX of Bacillus subtilis by means of PCR technique.
本研究利用聚合酶链式反应技术，成功地克隆了枯草芽孢杆菌缺陷型原噬菌体PBSX阻遏基因及其温度敏感型等位基因。
The researchers analyzed the function of the mutant proteins, establishing that it was the "triggering" kinase segment of the protein that was central to the enzyme's defective function.
研究人员分析了突变蛋白的功能，发现它是该蛋白激发激酶作用的部分，是酶缺矢功能的核心环节。
