A mutant probably harboring more plasmids can grow better on nitrobenzene selective medium than other strains. the plasmid harbored in this mutant is also a few kb smaller than others. so a probability is supposed that a certain plasmid dna fragment deletion made the number of plasmid copy change, which affected the mutant growth on the selective medium
一株質粒含量較高的突變株在硝基苯選擇培養基中的生長情況要好於其它菌株，其所含的質粒也略小一些，因此我們推測，某個質粒片段的缺失造成了質粒拷貝數的變化，從而影響了它的生長特性。
