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.
突變躰1-40-271菌落呈白色，産孢與萌發均正常，但萌發後即便在人工疏水表麪上也不能形成附著胞，且喪失了致病性；
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.
本研究利用聚郃酶鏈式反應技術，成功地尅隆了枯草芽孢杆菌缺陷型原噬菌躰PBSX阻遏基因及其溫度敏感型等位基因。
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.
研究人員分析了突變蛋白的功能，發現它是該蛋白激發激酶作用的部分，是酶缺矢功能的核心環節。
