One of the 10 rRNA gene sets found in a wild-type strain of Bacillus subtilis 168 was deleted, apparently by recombination between two tandemly repeated rRNA gene sets. The deletion strain grew as well as the wild-type strain under a variety of growth conditions and also showed no change in the sporulation efficiency.
枯草芽孢杆菌168野生型菌株中发现的10个rRNA基因集之一被删除,显然是通过两个串联重复的rRNA基因集之间的重组实现的。缺失菌株在各种生长条件下的生长情况与野生型菌株一样,并且在孢子形成效率上也没有变化。
