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.

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.

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.

Summary

Cultivated chickpea (Cicer arietinum) evolved reduced sensitivity to cold temperatures, unlike its wild progenitor. This adaptation facilitated its shift to spring sowing and wider geographic spread.

Background:

Understanding the domestication of chickpea (Cicer arietinum) is crucial for crop improvement.
Investigating the response to low temperatures during early growth reveals evolutionary adaptations.
Wild chickpea (Cicer reticulatum) serves as a key progenitor for studying domestication processes.

Purpose of the Study:

To investigate the response to low temperature during early growth in cultivated chickpea and its wild progenitor.
To clarify the evolutionary processes of chickpea under domestication, focusing on cold response.
To assess the genetic variation in low-temperature response within chickpea progeny.

Main Methods:

Exposure of parental lines and F2/F3 progeny of chickpea to cold treatment (4°C for 30 days) versus control conditions.
Comparison of flowering time and apical dominance between wild and cultivated chickpea under cold stress.
Analysis of genetic variation in flowering time response to low temperature in F3 progeny.

Main Results:

Cold treatment advanced flowering by 19 days in wild chickpea but only 3 days in cultivated chickpea.
Low temperature promoted apical dominance in wild chickpea, while it was constitutive in cultivated chickpea.
Significant genetic variation in flowering time response to low temperature was observed in F3 progeny.

Conclusions:

Selection against vernalization requirement alleles was a key step in chickpea evolution.
Reduced low-temperature response enabled chickpea's transition to a spring-sown crop and its spread to new regions.
Introgression with wild chickpea risks reintroducing cold-sensitive alleles, potentially impacting yield and stress resistance.
