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.

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

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.

Other Stress Responses in Bacteria

Other Stress Responses in Bacteria

Bacteria have global regulatory systems that control several types of stress mechanisms. These include Pho regulon and the heat shock response, which are essential systems for environmental adaptation, such as nutrient limitation and proteotoxic stress. The Pho regulon and the heat shock response exemplify bacterial resilience, enabling rapid adaptation to fluctuating environmental conditions.Pho RegulonBacteria require phosphorus for essential cellular processes, including nucleic acid...

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.

Primary and Secondary Growth in Roots and Shoots

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Summary

Plants use belowground microbes to manage aboveground stress, integrating signals from both environments. This plant-microbe communication enhances stress tolerance and adaptation to changing conditions.

Area of Science:

Plant science
Microbiology
Ecology

Background:

The microbiota-gut-brain axis in animals highlights microbial influence on host physiology.
Emerging evidence suggests plants utilize belowground microbes for aboveground stress responses.
Plant stress tolerance may involve integrating microbial and environmental cues.

Purpose of the Study:

To explore how plants use belowground microbes to manage aboveground stress.
To discuss the cascade of stress perception from shoots to roots and its effect on root microbiota.
To propose a model of microbiota-root-shoot circuits in plant adaptation.

Main Methods:

Review of reductionist and community-level studies on plant-microbe interactions.
Analysis of stress signal perception and its impact on root microbiota assembly.
Examination of microbial modulation of plant stress tolerance.

Main Results:

Aboveground stresses can alter root microbiota composition and the growth of beneficial microbes.
Plants integrate belowground microbial signals with aboveground environmental cues for stress management.
Root commensals influenced by the plant can enhance aboveground stress tolerance.

Conclusions:

Plant-microbe interactions belowground are crucial for aboveground stress responses.
Host modulation of microbiota-root-shoot circuits promotes plant phenotypic plasticity.
These mechanisms are vital for plant adaptation to dynamic environments.
