Fig. 3From: How do bifidobacteria counteract environmental challenges? Mechanisms involved and physiological consequencesSchematic representation of the stress gene regulatory network proposed for B. breve UCC2003. Dotted lines indicate the predicted interaction, and closed lines indicate a proven interaction. A dash at the end of a line indicates repression, while a triangle at the end of a line indicates activation. Connections between the various regulons occur at different levels, which is indicative of complex interactions. [Reproduced with ASM press permission, Copyright 2009; from [105]Back to article page
