RNA structure mediated thermoregulation: What can we learn from plants?

Frontiers in Plant Science, 2022
RNA molecules have the capacity to form a multitude of distinct secondary and tertiary structures, but only the most energetically favorable conformations are adopted at any given time. Formation of such structures strongly depends on the environment and

Thermostability of Two Cyanobacterial GrpE Thermosensors [PDF]

Plant and Cell Physiology, 2011
GrpE proteins act as co-chaperones for DnaK heat-shock proteins. The dimeric protein unfolds under heat stress conditions, which results in impaired interaction with a DnaK protein. Since interaction of GrpE with DnaK is crucial for the DnaK chaperone activity, GrpE proteins act as a thermosensor in bacteria.

Phytochromes function as thermosensors in Arabidopsis [PDF]

Science, 2016
Combining heat and light responses Plants integrate a variety of environmental signals to regulate growth patterns. Legris et al. and Jung et al. analyzed how the quality of light is interpreted through ambient temperature to regulate ...

Feeling cold is contagious [PDF]

, 2015
Seeing someone plunge into an ice-cold bath induces feelings of cold. However, it was recently demonstrated that viewing another's skin temperature change also induces a small congruent temperature change in the observer.

Paramagnetic Properties and Moderately RapidConformational Dynamics in the Cobalt(II) Calix[4]arene Complex by NMR

Molecules, 2022
1H NMR measurements are reported for the CD2Cl2/CDCl3 solutions of the Co(II) calix[4]arenetetraphosphineoxide complex (I). Temperature dependences of the 1H NMR spectra of I have been analyzed using the line shape analysis, taking into account the ...

Crystal structure of a thermophilic GrpE protein: insight into thermosensing function for the DnaK chaperone system. [PDF]

, 2010
A homodimeric GrpE protein functions as a nucleotide exchange factor of the eubacterium DnaK molecular chaperone system. The co-chaperone GrpE accelerates ADP dissociation from, and promotes ATP binding to, DnaK, which cooperatively facilitates the DnaK ...

Plant Thermosensors

Annual Review of Genetics
Plants are exposed to temperature conditions that fluctuate over different time scales, including those inherent to global warming. In the face of these variations, plants sense temperature to adjust their functions and minimize the negative consequences.

Monitoring the wear of the refractory lining in the blast-furnace hearth [PDF]

, 2013
The Razgar Gorna computer program is developed for calculating two-dimensional temperature fields in any vertical and horizontal cross section of the blast-furnace hearth. In the calculations, the heat-conduction equations are solved by means of readings
