Abstract
We have found that sporulation in Bacillus subtilis crsA47 mutants does not require the sigma(H)-dependent promoter of the spo0A gene. This implies that the glucose-resistant sporulation phenotype of this strain is not related to the switch from the vegetative-stage sigma(A)-dependent promoter to the sigma(H)-dependent promoter at the spo0A gene.
摘要
我们发现，枯草芽孢杆菌crsA47突变体中的芽孢形成并不需要spo0A基因的σ（H）依赖性启动子。这意味着该菌株的抗葡萄糖芽孢形成表型与spo0A基因从营养阶段的σ（A）依赖性启动子向σ（H）依赖性启动子的转换无关。
