Abstract
Mutations within P23, the first gene of the Bacillus subtilis sigma A operon, were not detrimental to vegetative growth or sporulation. One deletion of P23 resulted in a strain that sporulated earlier than the wild type. This aberrant phenotype may be due to the simultaneous deletion of a sigma H promoter from the sigma A operon.
摘要
枯草芽孢杆菌σA操纵子的第一个基因P23内的突变对营养生长或孢子形成没有不利影响。P23的一次缺失产生了一个比野生型更早形成孢子的菌株。这种异常表型可能是由于σA操纵子中一个σH启动子同时缺失所致。
