FIG. 3.
Hybridization of D. vulgaris macroarrays with labeled cDNA synthesized in vitro. (A) RNA extracted from wild-type cells grown in WP-LS medium. The entire macroarray is shown (145 spots, 15 columns, 10 rows). (B) RNA extracted from wild-type cells grown in WP medium with ethanol as the sole electron donor. Only row 5 of the array is shown. (C) RNA extracted from hyd mutant cells grown in WP-LS medium. Only row 5 of the array is shown. (D) RNA extracted from adh mutant cells grown in WP-LS medium. Only row 5 of the array is shown. The location of ORF2977 adh is indicated by an arrow. The array positions of other highly expressed genes are indicated in Table 3.
