[…] ed using SYBR premix Ex TaqTM (TaKaRa) in an Eco Real-Time PCR System (Illumina). Levels of 16S rRNA were used as internal control. The primers used for qRT-PCR are shown in . The fold changes of the sspA-1 transcripts were quantified using a comparative threshold cycle (ΔΔCT) program in the Eco software package. The assays were performed in triplicate. […]


Genome Wide Analysis of Cell Type Specific Gene Transcription during Spore Formation in Clostridium difficile

PLoS Genet
PMCID: 3789822
PMID: 24098137
DOI: 10.1371/journal.pgen.1003756

[…] xpression will require further investigations.It is worth noting that the expression of many sigG-controlled genes (82% of σG regulon members) including those for key sporulation proteins like SpoVA, SspA, SspB and PdaA was strongly reduced in a sigF mutant in transcriptome (). The absence of detection of the complete σG regulon in the sigF mutant might be due to the timing of sampling (14 h) that […]
