To study the functions of the uncharacterized open reading frames identified in the Bacillus subtilis genome, several vectors were constructed to perform insertional mutagenesis in the chromosome. All the pMUTIN plasmids carry a lacZ reporter gene and an inducible Pspac promoter, which is tightly regulated and can be induced about 1000-fold. 01/12/2016В В· Hence, there is uncertainty about whether the resulting insights can be extrapolated directly to other bacteria, such as the Gram-positive soil bacterium Bacillus subtilis. A recent study identified 1,583 putative regulatory RNAs in B. subtilis, whose expression was assessed across 104 conditions.
