FIG. 1.

Northern analyses of ech42, nag1, and gluc78 by T. atroviride after growth in EMM containing different levels of ammonium acetate (H = 100 mM; L = 10 mM) and glucose (H = 3%; L = 0.1%) in the presence or absence of colloidal chitin (1%). Expression levels at 24, 48, and 72 h after medium replacement are shown. All lanes were loaded with 7.5 μg of total RNA. Hybridizations were performed for 18 h at high stringency using PCR-generated DIG-labeled double-stranded-DNA-specific probes.
