Summary
Temperature signals influence the Arabidopsis circadian clock. Temperature-Dependent Alternative Splicing (TDAS) of clock genes offers a conserved mechanism for adapting circadian systems to varying temperatures across organisms.
Area of Science:
- Plant biology
- Molecular biology
- Genetics
Background:
- The circadian clock regulates daily biological rhythms.
- Temperature fluctuations can disrupt circadian clock function.
- Understanding temperature integration is crucial for plant adaptation.
Purpose of the Study:
- To review temperature signal integration in the Arabidopsis circadian clock.
- To propose Temperature-Dependent Alternative Splicing (TDAS) as a key adaptation mechanism.
- To highlight the conserved nature of TDAS across diverse organisms.
Main Methods:
- Literature review of circadian clock research.
- Analysis of gene splicing mechanisms in response to temperature.
- Comparative study of TDAS in different species.
Main Results:
- Temperature signals are integrated into the plant circadian clock.
- TDAS of core clock genes provides a mechanism for temperature adaptation.
- Evidence suggests TDAS is a conserved process in various organisms.
Conclusions:
- TDAS is a significant mechanism for circadian system adaptation to temperature.
- This conserved mechanism enhances organismal resilience to environmental changes.
- Further research into TDAS can reveal new avenues for crop improvement.

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

4.5K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

02:04Regulation of Transpiration by Stomata
30.9K
During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

4.3K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...
