Figure 1From: Nitrogen starvation-induced transcriptome alterations and influence of transcription regulator mutants in Mycobacterium smegmatisFunctional catagories of the M. smegmatis nitrogen starvation stimulon. DNA microarray analyses were carried out with RNA isolated from nitrogen-supplied and nitrogen-starved wild-type cells. Genes with decreased (A) and increased (B) transcript levels in response to nitrogen starvation were classified according to functional categories [13].Back to article page
