FIG. 2.

Northern analyses of gene deletion and control transformants to investigate the various p-gvpF-M transcripts. RNA samples were derived from the exponential (e) and stationary (s) growth phases. A 10-μg sample of total RNA was applied to each slot. Transcripts starting at the pF promoter were visualized using the FG probe (top), whereas the LM probe was used to detect transcripts starting at the fdx promoter in pJSA35 (bottom). The construct responsible for mRNA hybridization is indicated at the bottom of each gel. For the FG probe, the expected mRNA is indicated by an asterisk. The values on the side of each gel are the sizes (in kilobases) of the RNA markers.
