Figure 1From: Deciphering the response of Mycobacterium smegmatis to nitrogen stress using bipartite active modulesThe transcriptional response and growth of M. smegmatis under different nitrogen conditions. (A) Growth of M. smegmatis in 0Â mM (closed squares), 1Â mM (closed triangles) and 30Â mM (closed diamonds) ammonium sulphate (n = 3) (B) Average fold change in transcript levels for amt1, amtA, amtB, glnD, glnK, gltD and glnA1 during nitrogen limitation compared to nitrogen excess (n = 3). Expression data was normalised to sigA. Error bars represent SD. Significant induction of nitrogen stress response is observed at 12Â hours.Back to article page
