FIG. 2.
Northern analysis of total RNA isolated from cells grown under denitrifying conditions with either toluene (T) or pyruvate (P) as the carbon source and visualized with gene-specific probes derived from tutE, tutF, tutD, tutG, or tutH. Samples of digoxigenin-labeled RNA were included to serve as size markers (M) and are labeled (in kilobases) on the sides.
