By correlating the resistance or sensitivity to female-specific phages of strains carrying F plasmids with deletions for part of the region 32.6 to 42.9 F, cloned F fragments, and other plasmids, it was shown that the pif loci are located near and clockwise to a point on F with coordinate 38.3 F.
通过将携带F质粒且在F的32.6至42.9区域部分缺失的菌株对雌性特异性噬菌体的抗性或敏感性,与克隆的F片段及其他质粒进行关联分析,结果表明pif基因座位于F上坐标为38.3F的一点附近且按顺时针方向排列。
