Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Regulation of Transpiration by Stomata

Regulation of Transpiration by Stomata

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.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

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.

C4 Pathway and CAM

C4 Pathway and CAM

Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The C4 pathway is used by plants such as...

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.

Summary

This summary is machine-generated.

Drought stress increases root-released carbon, including carbohydrates and organic acids. Further research on trees, shrubs, and field conditions is needed to understand plant carbon allocation under drought.

Area of Science:

Plant Biology
Soil Science
Ecology

Background:

Root exudation and rhizodeposition are key plant carbon allocation pathways to soil.
These processes influence soil organic carbon stability and ecosystem function.
Drought stress impacts on these belowground carbon fluxes are not well understood.

Purpose of the Study:

To assess how drought stress affects root-derived carbon fluxes (root exudates, rhizodeposition).
To identify knowledge gaps for future research directions.

Main Methods:

A meta-analysis was conducted.
Quantified effects of drought stress on total carbon and compound classes in root exudation and rhizodeposition.

Main Results:

Root-released total carbon significantly increased under drought stress.
Carbohydrates and organic acids also increased, potentially driving total carbon responses.
Ecosystem, flowering type, cotyledon type, functional type, and drought intensity were key variables.

Conclusions:

Knowledge gaps exist regarding trees, shrubs, field studies, and drought intensity ranges.
Future research should measure total carbon, compound classes, and specific compounds.
Understanding root carbon responses to drought is vital for predicting terrestrial carbon cycling under climate change.
