·RNA-based thermosensors can achieve temperature sensing
We designed four different types of RNA-based thermosensors, including heat-inducible RNA-based thermosensor, heat-repressible RNA-based thermosensor, cold-inducible RNA-based thermosensor and cold-repressible RNA-based thermosensor. We designed more than 200 different thermosensors, and constructed their measurement device.
After the experiments, we got some inspired results. As figure 1 shows, heat-inducible RNA-based thermosensors' activities increase at elevated temperature. Heat-repressible RNA-based thermosensors' activity decrease with increasement of temperature. Besides, cold-inducibe RNA-based thermosensors show lower sensing temperature range than heat-repressible RNA thermosensor, their intensity decrease sharply from 15 to 20℃. And cold-repressible RNA-based thermosensors' activity decrease with decreasing temperature even below 29℃.

These values are normalized using the fluorescence/Abs600 of positive control. (A) includes 48 heat-inducible RNA-based thermosensors' activities at 29, 31, 35, 37, 39 and 42℃. (B) includes 23 heat-repressible RNA-based thermosensors' activities at 29, 37 and 42℃. (C) includes 10 cold-repressible RNA-based thermosensors' activities at 15, 25, 29, 35 and 37℃. (D) includes 8 cold-inducible RNA-based thermosensors' activities at 15, 20, 25℃. ·Features of RNA-based thermosensors can be computed using fitted curve
In order to make users select a thermosensor conveniently by getting the melting temperature, intensity and sensitivity of the thermosensors, we fitted a curve to reflect the relationship between the change of temperature and the expression intensity of thermosensors (Figure 2).
