Temperature is among the most important of the parameters that free-living microbes monitor. Microbial physiology needs to be readjusted in response to sudden temperature changes. When the ambient temperature rises or drops to potentially harmful levels, cells mount protective stress responses--so-called heat or cold shock responses, respectively ...

Structural Probing of RNA Thermosensors
2009Chemical probing of RNA structure has become one of the most popular approaches to map the conformation of RNA molecules of various sizes under well-defined experimental conditions. The method monitors the sensitivity of each nucleotide to various chemicals, which reflects its hydrogen-bonding environment within the RNA molecule.

Emerging Plant Thermosensors: From RNA to Protein
Trends in Plant Science, 2020How plants sense temperature is an important question. Here, we highlight recent achievements in identifying plant thermosensors, including RNA switch and protein-DNA binding ability. Finally, we borrow an idea from one recent mammalian study and propose a putative temperature-sensitive kinase as a thermosensory mechanism.

Opposite thermosensor in fruitfly and mouse
Nature, 2003Several members of the TRP (for transient receptor potential) family of ion channels act as physiological temperature sensors in mammals1,2,3,4,5,6, but it is not known whether the invertebrate TRP subfamilies that are found in the fruitfly Drosophila and the roundworm Caenorhabditis elegans can be directly activated by temperature.

Generation of synthetic RNA-based thermosensors
bchm, 2008Abstract Structured RNAs with fundamental sensory and regulatory potential have been discovered in all kingdoms of life. Bacterial RNA thermometers are located in the 5′-untranslated region of certain heat shock and virulence genes. They regulate translation by masking the Shine-Dalgarno sequence in a temperature-dependent manner.

Feeling the Heat: Searching for Plant Thermosensors
Trends in Plant Science, 2019To draw the complete picture of plant thermal signaling, it is important to find the missing links between the temperature cue, the actual sensing, and the subsequent response. In this context, several plant thermosensors have been proposed. Here, we compare these with thermosensors in various other organisms, put them in the context of thermosensing ...

RNA Thermosensors in Bacterial Pathogens
2009During the course of an infection, a pathogenic bacterium has to sense the environment and adjust its gene expression appropriately. One such environmental cue is the difference in temperature inside and outside the host. RNA thermosensors are structures that can respond to differences in temperature by altering their conformation and thereby allowing ...

A Near‐Infrared Fluorescence‐Based Optical Thermosensor
Chemistry – A European Journal, 2009AbstractA polymeric thermosensor composed of the thermo‐responsive block copolymer Pluronic F127 (PF127) and the near‐infrared (NIR) dye Cy5.5 can simply monitor, image, and analyze temperature changes. The thermoprobe exhibited linear NIR fluorescent emission changes (see figure) over a broad temperature range (0–80 °C).magnified ...
