Summary of "Thermal imaging as a non-invasive technique for analyzing circadian rhythms in plants."

1.Endogenous (~24 circadian) rhythms control an enormously diverse range of processes in plants and are, increasingly, the target of studies aimed at understanding plant performance. Although in the previous few decades most plant circadian research has focused on Arabidopsis, there is a pressing need for more low-cost, high-throughput tools for analyzing rhythms in a wider variety of species. Here we investigate using circadian temperature oscillations as a novel marker for assaying plant circadian rhythms. 2.A thermal imaging platform was set up and to measure diel and circadian rhythms in different plant species, in wild-type and circadian mutant plants and in leaves and flowers. Results from the thermal imaging technique were compared with those from other established circadian assay techniques. 3.All the dicot and monocot species we examined showed robust circadian rhythms of leaf surface temperature; the effects of circadian mutations on thermocycles were similar to those reported using other techniques. In Petunia x atkinsiana plants circadian oscillations were observed in both leaves and flowers. 4.Thermal imaging is an extremely useful technique for analyzing circadian rhythms in plants. We predict the ability to make very high temporal resolution measurements may facilitate the discovery of novel aspects of circadian control. This article is protected by copyright.

The adaptation of drug administration to the known variations in biological RHYTHMICITY, such as CIRCADIAN RHYTHMS. The treatment is aimed at supporting normal rhythms, or modifying the timing of therapy to achieve maximal efficacy and minimal adverse effect.

The adaptation of therapeutic approaches such as pharmacological (DRUG CHRONOTHERAPY), surgical, radiological, or physical to the known variations in biological RHYTHMICITY, such as CIRCADIAN RHYTHMS. The treatment is aimed at supporting normal rhythms, or modifying the timing of therapy to achieve maximal efficacy and minimal adverse effect.

Imaging of a ventricle of the heart after the injection of a radioactive contrast medium. The technique is less invasive than cardiac catheterization and is used to assess ventricular function.

Biological mechanism that controls CIRCADIAN RHYTHM. Circadian clocks exist in the simplest form in cyanobacteria and as more complex systems in fungi, plants, and animals. In humans the system includes photoresponsive RETINAL GANGLION CELLS and the SUPRACHIASMATIC NUCLEUS that acts as the central oscillator.

Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
