thermosensors
Also known as: temperature-controlled gene expression modules
Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Thermosensors are stimuli-sensitive gene expression modules used in bacterial hosts for conditional expression of genes of interest. The supplied evidence describes them at a review level as systems in which temperature, and in some contexts light, regulates gene expression through structural changes in responsive biomolecules.
Usefulness & Problems
Why this is useful
These modules are useful for conditional control of gene expression in bacterial systems using external physical stimuli. The evidence supports their general value as components of genetic circuits that respond to temperature shifts, but it does not provide tool-specific performance data.
Problem solved
Thermosensors help address the need for externally controllable gene expression modules in bacterial hosts. Specifically, they provide a way to induce or repress genes of interest in response to thermal stimuli through stimulus-responsive structural switching.

The available evidence only states that these systems are used in bacterial hosts for conditional expression of genes of interest. No construct design, RNA sequence features, cofactors, delivery methods, or expression conditions are provided in the supplied material.
The supplied evidence is review-level and does not identify a specific thermosensor sequence, RNA architecture, host range, dynamic range, response time, or benchmarked expression output. It also conflates thermosensors with light-driven systems, so the role of light as an input for this RNA element is not resolved from the provided text.
