Results
We added 10 cold-reprssible RNA-based thermosensors and 8 cold-inducible RNA-based thermosensors to the SynRT Toolkit. After that, we named the updated toolkit as SynRT Toolkit version 3.0.
Cold-repressible RNA-based thermosensors
Cold-repressible RNA-based thermosensors are designed based on the RNase III. We constructed their measurement devices and measured the activities at five temperatures: 15, 25, 29, 35 and 37℃. The measured temperature range is lower than the heat-inducible RNA-based thermosensors' temperature range. We also designed a new negtive control, which always has a cleavage site of RNase III, so it will be digest by the enzyme. After measurement, we chose 10 out of 50 thermosensors.
Figure 1 shows the change of activities of different thermosensors. We find that all of these thermosensors' activities decrease with temperature decreasing.
For most of the heat-inducible RNA-based thermosensors, the sensing temperature range is between 30 to 40. However, for the cold-repressible RNA-based thermosensors, the sensing temperature range decrease to 15~35℃.
Discussion: As these results show, cold-repressible RNA-based thermosensors work really well. Their activities decrease with the temperature decreasing. And the sensing temperature range is different from heat-inducible RNA-based thermosensors'. Cold repressible RNA-based thermosensor can sense lower temperature.
