FIG. 3.

DDR48, RTA2, and orf19.675 transcript levels in wild-type and mutant strains. Equal amounts of total RNA from the wild-type and mutant strains were separated by electrophoresis, blotted onto nylon membranes, and probed with ³²P-labeled DNA probes specific for DDR48, RTA2, orf19.675, and ACT1 (actin). The transcript levels were quantified with a phosphorimager and normalized relative to the actin transcript levels. The numbers below each panel correspond to the fold expression relative to the wild type.
