Expression plots of cis- (cspA) and trans -encoded (RNaseP) sRNAs from B. thailandensis based on microarray analysis. (A) CspA is a sRNA prediction from Rfam (red) and resides upstream of predicted gene BTH_I2936. CspA expression was downregulated at 37°C (yellow to red-labeled expression profiles) compared to 25°C (grey expression profile). Predicted genes and terminators are shown in green and black triangles, respectively. (B) RNaseP is a predicted sRNA from Rfam (red). RNaseP was expressed independently from flanking genes at high levels in response to practically all conditions tested.
