Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

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.

pH Regulation in Cells

pH Regulation in Cells

pH plays a critical role in maintaining normal cellular activities. It helps maintain the structure and function of various proteins, dictates the charge on cellular membranes, and is crucial for metabolic reactions inside the cell. Moreover, cells use the energy from the proton motive force to generate ATP.
Cytosolic pH
Under physiological conditions, the cytosolic pH is slightly more acidic than the extracellular pH. However, cells must prevent further acidification of their cytosol to...

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

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.

Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Stomach pH Regulation

Stomach pH Regulation

The human body carefully regulates the internal pH of different organs to maintain homeostasis. For example, while the blood plasma maintains a neutral pH of 7, the stomach lumen has an acidic pH of 1.5 - 3.5. The low pH of stomach lumen helps kill pathogens in the food and break down complex food molecules.
The acid-secreting gastric mucosal epithelial cells (parietal cells) lining the stomach lumen maintain the low pH in the lumen. Numerous ion transporters and channels on these parietal...

Area of Science:

Plant Science
Environmental Science
Molecular Biology

Background:

The phylloplane is the initial plant-environment interface.
Understanding plant responses to external pH, like acid rain, is crucial but molecular mechanisms are unclear.

Purpose of the Study:

To investigate plant phylloplane pH modification capabilities.
To identify species-specific pH buffering and molecular responses to pH stress.

Main Methods:

Measured phylloplane pH across five species under varying pH treatments (6.5, 4, 2).
Conducted transcriptional analysis to identify differentially expressed genes.
Assessed impacts on photosynthesis and stress signaling.

Main Results:

Plants exhibit species-specific phylloplane pH buffering.
Gossypium demonstrated significant buffering, notably at pH 2, raising pH to 6 within minutes.
Transcriptional analysis revealed differential gene expression in calcium signaling and ion transport pathways.
pH stress affected photosynthesis and may activate other stress pathways.

Conclusions:

Plant phylloplane pH buffering is a species-specific defense mechanism.
Gossypium possesses a robust ability to neutralize acidic conditions on its leaf surface.
External pH changes trigger complex molecular responses involving ion transport and stress signaling, impacting photosynthesis.
