FIG 4.
Transcription analysis of Tlys and Tind. (A) Schematic representation of the head-to-head-oriented transcripts Tind and Tlys. (B) SSV1-InF1 total RNAs isolated from mock- and UV-treated cells at different time points were analyzed by Northern hybridization to detect Tlys and Tind transcripts. The hybridization signals were normalized using the 16S housekeeping gene. The Tind transcript was expressed over a short time and only in UV-irradiated cells, whereas Tlys was detectable in both mock-treated and UV-irradiated cells. Degradation occurred around the 8th to 10th hour only for the Tlys transcript.
