From: Gene expression of putative type VI secretion system (T6SS) genes in the emergent fish pathogen Francisella noatunensis subsp. orientalis in different physiochemical conditions

Fig. 4

Expression profile of Francisella noatunensis subsp. orientalis putative T6SS genes, iglA, iglB, pdpB, vgrG, and dotU when exposed to different concentrations of hydrogen peroxide for 1 h (a), 6 h (b) or 24 h (c). Gene expression was determined by qRT-PCR, using relative quantification. Gene expression was normalized by the housekeeping gene ftsZ. Zero hour of growth at 0 mM was used as calibrator (value =1). The error bars represent the standard deviation of nine replicate samples from three independent experiments. Statistically significant differences relative to the same period of time at 0 mM are marked (*, P < 0.05)
